Class Name: androgen (Oral route, Parenteral route, Subcutaneous route, Topical application route, Transdermal route)
In the U.S.
In Canada
Available Dosage Forms:
Androgens are male hormones. Some androgens are naturally produced in the body and are necessary for the normal sexual development of males.
Androgens are used for several reasons, such as:
In addition, some of these medicines may be used for other conditions as determined by your doctor.
Androgens are available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, androgens are used in certain patients with the following medical conditions:
Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Androgens may cause children to stop growing. In addition, androgens may make male children develop too fast sexually and may cause male-like changes in female children
When older male patients are treated with androgens, they may have an increased risk of enlarged prostate (a male gland) or their existing prostate cancer may get worse. For these reasons, a prostate examination and a blood test to check for prostate cancer is often done before androgens are prescribed for men over 50 years of age. These examinations may be repeated during treatment.
Androgens are not recommended during pregnancy. When given to pregnant women, the medicine has caused male features to develop in female babies.
Use is not recommended in nursing mothers, since androgens may pass into the breast milk and may cause unwanted effects in the nursing baby, such as premature (too early) sexual development in males and development of male features in female babies.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking any of these medicines, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using medicines in this class with any of the following medicines is not recommended. Your doctor may decide not to treat you with a medication in this class or change some of the other medicines you take.
Using medicines in this class with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
The presence of other medical problems may affect the use of medicines in this class. Make sure you tell your doctor if you have any other medical problems, especially:
Take this medicine only as directed. Do not take more of it and do not take it more often than your doctor ordered . Doing so may increase the chance of side effects.
There are two types of testosterone skin patches. The matrix-type is applied to skin of the scrotum. The reservoir-type is never applied to the skin of the scrotum. It is applied to other parts of the body. Be sure you know which type you are using so that you will apply it properly. These skin patches come with patient directions. Read them carefully before using the patch.
For patients taking fluoxymesterone or methyltestosterone:
For patients using the matrix-type skin patch of testosterone (Testoderm or Testoderm with Adhesives):
For patients using the reservoir-type skin patch of testosterone (Androderm or Testoderm TTS):
The dose medicines in this class will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of these medicines. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
If you miss a dose of this medicine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
If you forget to wear or change a patch, put one on as soon as you can. If it is almost time to put on your next patch, wait until then to apply a new patch and skip the one you missed. Do not apply extra patches to make up for a missed dose.
For topical dosage forms (patches): If you miss a dose of this medicine or your patch falls off within 12 hours after applying it and cannot be reapplied, skip the rest of the dose and go back to your regular dosing schedule. Do not double doses.

Your doctor should check your progress at regular visits to make sure this medicine does not cause unwanted effects.
For patients with diabetes mellitus (sugar diabetes):
For patients using the brand name Androgel:
Discuss these possible effects with your doctor:
Tumors of the liver, liver cancer, or peliosis hepatis (a form of liver disease) have occurred during long-term, high-dose therapy with androgens. Although these effects are rare, they can be very serious and may cause death.
Androgens can stimulate existing prostate cancer in men who already have it but have not yet been diagnosed. Also, the prostate (a male gland) may become enlarged. Enlargement of the prostate does not mean that cancer will develop. If enlargement occurs and you have difficulty in urinating, it is a good idea to be checked by your doctor.
When androgens are used in women, especially in high doses, male-like changes may occur, such as hoarseness or deepening of the voice, unnatural hair growth, or unusual hair loss. Most of these changes will go away if the medicine is stopped as soon as the changes are noticed. However, some changes, such as voice changes or enlarged clitoris, may not go away.
When androgens are used in high doses in males, they interfere with the production of sperm. This effect is usually temporary and only happens during the time you are taking the medicine. However, discuss this possible effect with your doctor if you are planning on having children.
Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Check with your doctor immediately if any of the following side effects occur:
These symptoms may occur in females whose male sexual partner uses a scrotal patch.
Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:
Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.
Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

Topotecan hydrochloride should be administered only to patients with baseline neutrophil counts of at least 1500 cells/mm(3) and a platelet count of at least 100,000 cells/mm(3). In order to assess the occurrence of bone marrow suppression, blood cell counts should be monitored .
In the U.S.
Available Dosage Forms:
Therapeutic Class: Antineoplastic Agent
Pharmacologic Class: Topoisomerase I Inhibitor
Topotecan is used to treat small cell lung cancer that has relapsed or gotten worse. It belongs to the group of medicines known as antineoplastics or cancer medicines.
Topotecan interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal cells may also be affected by the medicine, other unwanted effects may occur. Some of these may be serious and must be reported to your doctor. Some effects, like hair loss, may not be serious but may cause concern. Some unwanted effects may occur after treatment with topotecan has stopped.
topotecan is available only with your doctor's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For topotecan, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to topotecan or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of topotecan in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of topotecan in the elderly. However, elderly patients are more likely to have diarrhea and age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving topotecan.
| Pregnancy Category | Explanation | |
|---|---|---|
| All Trimesters | D | Studies in pregnant women have demonstrated a risk to the fetus. However, the benefits of therapy in a life threatening situation or a serious disease, may outweigh the potential risk. |
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur.

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
The presence of other medical problems may affect the use of topotecan. Make sure you tell your doctor if you have any other medical problems, especially:
Medicines used to treat cancer are very strong and can have many side effects. Before receiving topotecan, make sure you understand all of the risks and benefits. It is important for you to work closely with your doctor during your treatment.
Take topotecan only as directed by your doctor to benefit your condition as much as possible. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.
Swallow the capsule whole with water. Do not open, crush, break, or chew it.
You may take topotecan with or without food.
Be careful not to handle broken or leaking capsules. If you get the contents from the capsule on your skin, wash the area with soap and water and call your doctor right away. If the medicine gets in your eyes, rinse them immediately with gently flowing water for at least 15 minutes and call your doctor right away.
Topotecan often causes nausea and vomiting. It is very important that you continue to receive the medicine even if it makes you feel ill. Ask your doctor for ways to lessen these effects.
The dose of topotecan will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of topotecan. If your dose is different, do not change it unless your doctor tells you to do so.

It is very important that your doctor check your progress at regular visits to make sure topotecan is working properly. Blood tests are needed to check for unwanted effects.
Using topotecan while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using the medicine, tell your doctor right away.
Topotecan can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
Topotecan may cause diarrhea, and in some cases it can be severe. Do not take any medicine to treat diarrhea without first checking with your doctor. Diarrhea medicines may make the diarrhea worse or make it last longer. If you have any questions about this or if mild diarrhea continues or gets worse, check with your doctor.
topotecan may cause some people to become more tired or weaker than they are normally. If either of these side effects occurs, do not drive, use machines, or do anything else that could be dangerous if you are not alert.
Stop using topotecan and check with your doctor right away if you have breathing problems, a cough, a fever, a fast heartbeat, or shortness of breath. These could be symptoms of a serious lung problem.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

Generic Name: measles, mumps, rubella and varicella virus vaccine (MEE zels, MUMPS, roo BEL a, var i SEL a)
Brand Names: ProQuad
Measles, mumps, rubella, and varicella are serious diseases caused by viruses. They are spread from person to person through the air.
Measles virus can cause minor symptoms such as skin rash, cough, runny nose, eye irritation, or mild fever. It can also cause more serious symptoms such as ear infection, pneumonia, seizures, permanent brain damage, or death.
Mumps virus causes fever, headache, and swollen glands, but more serious symptoms include hearing loss, and painful swelling of the testicles or ovaries. Mumps can cause breathing problems or meningitis, and these infections can be fatal.
Rubella virus (also called German Measles) causes skin rash, mild fever, and joint pain. Becoming infected with rubella during pregnancy can result in a miscarriage or serious birth defects.
Varicella (commonly known as chickenpox) is a common childhood disease that causes fever, skin rash, and a breakout of fluid-filled blisters on the skin. Most people who receive this vaccine will not get chickenpox, or will get only a mild case and will recover faster. Chickenpox is usually mild, but it can be serious or even fatal in young infants and in adults. It can lead to severe skin infection, breathing problems, brain damage, or death. A person who has had chickenpox can develop herpes zoster (also called shingles) later in life, which causes severe nerve pain, and hearing or vision problems, which may last for months or years.
Measles, mumps, rubella, and varicella are spread from person to person.
The measles, mumps, rubella, and varicella vaccine is used to help prevent these diseases in children. This vaccine works by exposing your child to a small dose of the virus or a protein from the virus, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.
Measles, mumps, rubella, and varicella vaccine is for use in children between the ages of 12 months and 12 years old.
Like any vaccine, the measles, mumps, rubella, and varicella vaccine may not provide protection from disease in every person.
The measles, mumps, rubella, and varicella vaccine is usually given only once when the child is between 12 months and 12 years old. If a booster dose is needed, At least 3 months should pass between the first and second doses of this vaccine.
Becoming infected with measles, mumps, rubella, or varicella is much more dangerous to your child's health than receiving this vaccine. However, like any medicine, this vaccine can cause side effects but the risk of serious side effects is extremely low.
Do not give your child salicylates such as aspirin, Disalcid, Doan's Pills, Dolobid, Salflex, Tricosal, and others for at least 6 weeks after receiving this vaccine. A serious condition called Reye's Syndrome has been reported in patients with chickenpox who take aspirin or salicylates.
Your child should also not receive this vaccine if he or she has:
active tuberculosis infection;
a cancer such as leukemia or lymphoma;
a history of Guillain-Barré syndrome;
a chronic disease such as asthma or other breathing disorder, diabetes, kidney disease, or a blood cell disorder such as anemia;
severe immune suppression caused by disease (such as cancer, HIV, or AIDS), or by receiving certain medicines such as steroids, chemotherapy or radiation;
if the child has recently taken aspirin or other similar medicines such as Disalcid, Doan's Pills, Dolobid, Salflex, Tricosal, and others;
if the child has recently received a stem cell transplant;
if someone in the child's household has a weak immune system; or
if the child is pregnant.
If your child has any of these other conditions, this vaccine may need to be postponed or not given at all:
thrombocytopenia purpura (easy bruising or bleeding);
a history of seizures;
a neurologic disorder or disease affecting the brain (or if this was a reaction to a previous vaccine);
a weak immune system caused by disease, bone marrow transplant, or by using certain medicines or receiving cancer treatments;
if the child has received an immune globulin or other blood product within the past year; or
if the child has received a measles, mumps, and rubella (MMR) vaccine within the past 28 days (4 weeks).
Your child can still receive a vaccine if he or she has a minor cold. In the case of a more severe illness with a fever or any type of infection, wait until the child gets better before receiving this vaccine.
This vaccine is given as an injection under the skin. You will receive this injection in a doctor's office or clinic setting.
The measles, mumps, rubella, and varicella vaccine is usually given only once when the child is between 12 months and 12 years old. If a booster dose is needed, At least 3 months should pass between the first and second doses of this vaccine.
Your child's booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by your local health department.
Your doctor may recommend treating fever and pain with an aspirin free pain reliever such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil, and others) when the shot is given and for the next 24 hours. Follow the label directions or your doctor's instructions about how much of this medicine to give your child.
It is especially important to prevent fever from occurring in a child who has a seizure disorder such as epilepsy.
This vaccine can cause false results on a skin test for tuberculosis for up to 6 weeks. Tell any doctor who treats you if you have received this vaccine within the past 4 to 6 weeks.
Since this vaccine is usually given only once, you are not likely to miss a dose. Contact your doctor if you do not receive all recommended doses.
An overdose of this vaccine is unlikely to occur.

Losartan potassium 25 mg film-coated tablets
Each film-coated tablet contains 25 mg losartan potassium, equivalent to 22.9 mg losartan
Excipient:
Losartan 25 mg film-coated tablets: lactose
For a full list of excipients, see section 6.1.
Film-coated tablets
White, oval-shaped, film-coated tablet with score line on both sides. The film-coated tablet can be divided into equal halves.
• Treatment of essential hypertension in adults and in children and adolescents 6-18 years of age.
• Treatment of chronic heart failure (in patients especially cough, or contraindication. Patients with heart failure who have been stabilised with an ACE inhibitor should not be switched to losartan. The patients should have a left ventricular ejection fraction
Losartan tablets should be swallowed with a glass of water
Losartan tablets may be administered with or without food.
Hypertension
The usual starting and maintenance dose is 50 mg once daily for most patients. The maximal antihypertensive effect is attained 3-6 weeks after initiation of therapy. Some patients may receive an additional benefit by increasing the dose to 100 mg once daily (in the morning). Losartan may be administered with other antihypertensive agents, especially with diuretics (e.g. hydrochlorothiazide).
Heart Failure
The usual initial dose of Losartan in patients with heart failure is 12.5 mg once daily. The dose should generally be titrated at weekly intervals (i.e. 12.5 mg daily, 25 mg daily, 50 mg daily) to the usual maintenance dose of 50 mg once daily, as tolerated by the patient.
Special populations:
Use in patients with intravascular volume depletion:
For patients with intravascular volume-depletion (e.g. those treated with high-dose diuretics), a starting dose of 25 mg once daily should be considered (see section 4.4).
Use in patients with renal impairment and haemodialysis patients:
No initial dosage adjustment is necessary in patients with renal impairment and in haemodialysis patients.
Use in patients with hepatic impairment
A lower dose should be considered for patients with a history of hepatic impairment. There is no therapeutic experience in patients with severe hepatic impairment. Therefore, losartan is contraindicated in patients with severe hepatic impairment (see sections 4.3 and 4.4).
Use in paediatric patients
There are limited data on the efficacy and safety of losartan in children and adolescents aged 6-18 years old for the treatment of hypertension (see section 5.1). Limited pharmacokinetic data are available in hypertensive children above one month of age (see section 5.2).
For patients who can swallow tablets, the recommended dose is 25 mg once daily in patients>20 to <50 kg. In exceptional cases the dose can be increased to a maximum of 50 mg once daily. Dosage should be adjusted according to blood pressure response.
In patients>50 kg, the usual dose is 50 mg once daily. In exceptional cases the dose can be adjusted to a maximum of 100 mg once daily. Doses above 1.4 mg/kg (or in excess of 100 mg) daily have not been studied in paediatric patients.
Losartan is not recommended for use in children under 6 years old, as limited data are available in these patient groups.
It is not recommended in children with glomerular filtration rate < 30 ml/min / 1.73 m², as no data are available (see also section 4.4).
Losartan is also not recommended in children with hepatic impairment (see also section 4.4).
Use in the elderly
Although consideration should be given to initiating therapy with 25 mg in patients over 75 years of age, dosage adjustment is not usually necessary for the elderly.
Hypersensitivity to the active substance or to any of the excipients (see section 4.4 and 6.1)
Second and third trimesters of pregnancy (see section 4.4 and 4.6)
Severe hepatic impairment
Hypersensitivity
Angiooedema. Patients with a history of angiooedema (swelling of the face, lips, throat, and/or tongue) should be closely monitored (see section 4.8).
Hypotension and Electrolyte/Fluid Imbalance
Symptomatic hypotension, especially after the first dose and after increasing of the dose, may occur in patients who are volume- and/or sodium-depleted by vigorous diuretic therapy, dietary salt restriction, diarrhoea or vomiting. These conditions should be corrected prior to administration of Losartan; or a lower starting dose should be used (see section 4. 2). This also applies to children.
Electrolyte imbalances
Electrolyte imbalances are common in patients with renal impairment, with or without diabetes, and should be addressed. In a clinical study conducted in type 2 diabetic patients with nephropathy, the incidence of hyperkalemia was higher in the group treated with Losartan as compared to the placebo group (see section 4.8) Therefore, the plasma concentrations of potassium as well as creatinine clearance values should be closely monitored, in particular, patients with heart failure and a creatinine Clearance between 30-50 ml/min should be closely monitored.
The concomitant use of potassium sparing diuretics, potassium supplements and potassium containing salt substitutes with losartan is not recommended (sec section 4.5).
Liver HepaticImpairment
Based on pharmacokinetic data which demonstrate significantly increased plasma concentrations of losartan in cirrhotic patients, a lower dose should be considered for patients with a history of hepatic impairment. There is no therapeutic experience with losartan in patients with severe hepatic impairment. Therefore losartan must not be administered in patients with severe hepatic impairment (see sections 4.2, 4.3 and 5.2).
Losartan is also not recommended in children with hepatic impairment (see section 4.2).
Renal Impairment
As a consequence of inhibiting the renin-angiotensin system, changes in renal function including renal failure have been reported (in particular, in patients whose renal function is dependent on the renin angiotensin aldosterone system such as those with severe cardiac insufficiency or pre-existing renal dysfunction). As with other drugs that affect the renin-angiotensin-aldosterone system, increases in blood urea and serum creatinine have also been reported in patients with bilateral renal artery stenosis or stenosis of the artery to a solitary kidney; these changes in renal function may be reversible upon discontinuation of therapy. Losartan should be used with caution in patients with bilateral renal artery stenosis or stenosis of the artery to a solitary kidney.
Use in paediatric patients with renal function impairment
Losartan is not recommended in children with glomerular filtration rate < 30ml/min/1.73 m2 as no data are available (see section 4.2).
Renal function should be regularly monitored during treatment with losartan as it may deteriorate. This applies particularly when losartan is given in the presence of other conditions (fever, dehydration) likely to impair renal function.
Concomitant use of losartan and ACE-inhibitors has shown to impair renal function. Therefore, concomitant use is not recommended.
Renal transplantation
There is no experience in patients with recent kidney transplantation.
Primary hyperaldosteronism
Patients with primary aldosteronism generally will not respond to antihypertensive medicinal productsacting through inhibition of the renin-angiotensin system. Therefore, the use of Losartan tablets is not recommended.
Coronary heart disease and cerebrovascular disease
As with any antihypertensive agents, excessive blood pressure decrease in patients with ischaemic cardiovascular and cerebrovascular disease could result in a myocardial infarction or stroke.
Heart failure
In patients with heart failure, with or without renal impairment, there is - as with other medicinal products acting on the renin-angiotensin system - a risk of severe arterial hypotension, and (often acute) renal impairment.
There is no sufficient therapeutic experience with losartan in patients with heart failure and concomitant severe renal impairment, in patients with severe heart failure (NYHA class IV) as well as in patients with heart failure and symptomatic life threatening cardiac arrhythmias. Therefore, losartan should be used with caution in these patient groups. The combination of losartan with a beta-blocker should be used with caution (see section 5.1).
Aortic and mitral valve stenosis, obstructive hypertrophic cardiomyopathy
As with other vasodilators, special caution is indicated in patients suffering from aortic or mitral stenosis, or obstructive hypertrophic cardiomyopathy.
Excipients
Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
Pregnancy
AIIRAs should not be initiated during pregnancy. Unless continued AIIRA therapy is considered essential, patients planning pregnancy should be changed to alternative anti-hypertensive treatments which have an established safety profile for use in pregnancy. When pregnancy is diagnosed, treatment with AIIRAs should be stopped immediately, and, if appropriate, alternative therapy should be started (see sections 4.3 and 4.6).
Other warnings and precautions:
As observed for antiotensin converting enzyme inhibitors, losartan and the other angiotensin antagonists are apparently less effective in lowering blood pressure in black people than in non-blacks, possibly because of higher prevalence of low-renin states in the black hypertensive population.
Other antihypertensive agents may increase the hypotensive effects of losartan. Concomitant use withother substances inducing hypotension (like tricyclic antidepressants, antipsychotics, baclofen, and amifostine), may increase the risk of hypotension.
Losartan is predominantly metabolised by cytochrome P450 (CYP) 2C9 to the active carboxy-acid metabolite. In a clinical trial it was found that fluconazole (inhibitor of CYP2C9) decreases the exposure to the active metabolite by approximately 50%. It was found that concomitant treatment of losartan with rifampicine (inducer of metabolism enzymes) gave a 40% reduction in plasma concentration of the active metabolite. The clinical relevance of this effects is unknown. No difference in exposure was found with concomitantly treatment with fluvastatin (weak inhibitor of CYP2C9).
As with other drugs that block angiotensin II or its effects, concomitant use of other drugs which retain potassium (e.g. potassium-sparing diuretics: amiloride, triamteren, spironolactone) or may increase potassium levels (e.g. heparin), potassium supplements or salt substitutes containing potassium may lead to increases in serum potassium. Co-medication is not advisable.
Reversible increases in serum lithium concentrations and toxicity have been reported during concomitant administration of lithium with ACE inhibitors. Very rare cases have also been reported with angiotensin II receptor antagonists. Co-administration of lithium and losartan should be undertaken with caution. If this combination proves essential, serum lithium level monitoring is recommended during concomitant use.
When angiotensin II antagonists are administered simultaniously with NSAIDs (i.e. selective COX-2 inhibitors, acetylsalicylic acid at anti-inflammatory dosesand non-selective NSAIDs), attenuation of the antihypertensive effect may occur. Concomitant use of angiotensin II antagonists or diuretics and NSAIDs may lead to an increased risk of worsening of renal function, including possible acute renal failure, and an increase in serum potassium, especially in patients with poor pre-existing renal function. The combination should be administered with caution, especially in the elderly. Patients should be adequately hydrated and consideration should be given to monitoring renal function after initiation of concomitant therapy, and periodically thereafter.
Pregnancy
|
Epidemiological evidence regarding the risk of teratogenicity following exposure to ACE inhibitors during the first trimester of pregnancy has not been conclusive; however a small increase in risk cannot be excluded. Whilst there is no controlled epidemiological data on the risk with Angiotensin II Receptor Inhibitors ( AIIRAs), similar risks may exist for this class of drugs. Unless continued AIIRA-therapy is considered essential, patients planning pregnancy should be changed to alternative anti-hypertensive treatments which have an established safety profile for use in pregnancy. When pregnancy is diagnosed, treatment with AIIRAs should be stopped immediately, and, if appropriate, alternative therapy should be started.
Exposure to AIIRA therapy during the second and third trimesters is known to induce human fetotoxicity (decreased renal function, oligohydramnios, skull ossification retardation) and neonatal toxicity (renal failure, hypotension, hyperkalaemia) (see section 5.3).
Should exposure to AIIRAs have occurred from the second trimester of pregnancy, ultrasound check of renal function and skull is recommended.
Infants whose mothers have taken AIIRAs should be closely observed for hypotension (see section 4.3 and 4.4).
Lactation
Because no information is availabel regarding the use of Losartan during breastfeeding, Losartan is not recommended and alternative treatments with better established safety profiles during breast-feeding are preferable, especially while nursing a newborn or preterm infant.
No studies on the effects on the ability to drive and use machines have been performed.
However, when driving vehicles or operating machinery it must be borne in mind that dizziness or drowsiness may occasionally occur when taking antihypertensive therapy, in particular during initiation of treatment or when the dose is increased.
Losartan has been evaluated in clinical studies as follows:
• In controlled clinical trials in approximately 3300 adult patients 18 years of age and older for essential hypertension
• In a controlled clinical trial in 9193 hypertensive patients 55 to 80 years of age with left ventricular hypertrophy

Paediatric population
The adverse experience profile for paediatric patients appears to be similar to that seen in adult patients. Data in the paediatric population are limited.
Symptoms of intoxication
Limited data are available with regard to overdose in humans. The most likely symptoms, depending on the extent of overdose, are hypotension, tachycardia, possibly bradycardia.
Treatment of intoxications
If symptomatic hypotension should occur, supportive treatment should be instituted. Measures are depending on the time of drug intake and kind and severity of symptoms. Stabilisation of the circulatory system should be given priority. After oral intake the administration of a sufficient dose of activated charcoal is indicated. Afterwards, close monitoring of the vital parameters should be performed. Vital parameters should be corrected if necessary.
Neither losartan nor the active metabolite can by removed by haemodialysis.
Pharmacotherapeutic group: Angiotensin II Receptor Antagonists, ATC code: C09CA01
Pharmacotherapeutic group: Angiotensin II antagonists, plain, ATC code: C09CA01
Losartan is a synthetic oral angiotensin-II receptor (type AT1) antagonist. Angiotensin II, a potent vasoconstrictor, is the primary active hormone of the renin-angiotensin system and an important determinant of the pathophysiology of hypertension. Angiotensin II binds to the AT1 receptor found in many tissues (e.g. vascular smooth muscle, adrenal gland, kidneys, and the heart) and elicits several important biological actions, including vasoconstriction and the release of aldosterone. Angiotensin II also stimulates smooth-muscle cell proliferation.
Losartan selectively blocks the AT1 receptor. In vitro and in vivo, both losartan and its pharmacologically active carboxylic acid metabolite E-3174 block all physiologically relevant actions of angiotensin II, regardless of its source or route of synthesis.
Losartan does not have an agonist effect, nor does it block other hormone receptors or ion channels important in cardiovascular regulation. Furthermore, losartan does not inhibit ACE (kininase II), the enzyme that degrades bradykinin. Consequently, there is no potentiation of undesirable bradykinin-mediated effects.
During administration of losartan, removal of angiotensin II negative feedback on renin secretion leads to increased plasma-renin activity (PRA). Increases in PRA lead to increases in angiotensin II in plasma. Despite these increases, antihypertensive activity and suppression of plasma aldosterone concentration are maintained, indicating effective angiotensin II receptor blockade. After discontinuation of losartan, PRA and angiotensin II values fell within three days to baseline values.
Both losartan and its principal active metabolite have a far greater affinity for the AT1 receptor than for the AT2 receptor. The active metabolite is 10 to 40 times more effective than losartan on a weight for weight basis.
Hypertension studies
In controlled clinical studies, once-daily administration of losartan to patients with mild to moderate essential hypertension produced statistically significant reductions in systolic and diastolic blood pressure. Measurement of blood pressure 24 hours post-dose relative to 5-6 hours post-dose demonstrated blood pressure reduction over 24 hours; the natural diurnal rhythm was retained. Blood-pressure reduction at the end of the dosing interval was approximately 70-80% of the effect seen 5-6 hours post-dose.
Discontinuation of losartan in hypertensive patients did not result in an abrupt rise in blood pressure (rebound). Despite the marked decrease in blood pressure, losartan had no clinically significant effect on heart rate.
Losartan is equally effective in males and females, and in younger (below the age of 65 years) and older hypertensive patients.
ELITE I and ELITE II Study
In the ELITE Study carried out over 48 weeks in 722 patients with heart failure (NYHA Class II-IV, no difference was observed between the patients treated with Losartan and those treated with captopril was observed with regard to the primary endpoint of a long-term change in renal function. The observation of the ELITE I Study was that, compared with captopril, Losartan reduced the mortality risk, was not confirmed in the subsequent ELITE II Study.
In the ELITE II Study Losartan 50 mg once daily (starting dose 12.5 mg, increased to 25 mg, then 50 mg once daily) was compared with captopril 50 mg three times daily (starting dose 12.5 mg, increased to 25 mg and then to 50 mg three times daily). The primary endpoint of this prospective study was the all-cause mortality.
In this study 3152 patients with heart failure (NYHA Class Il-IV) were followed for almost two years (median: 1.5 years) in order to determine whether Losartan is superior to captopril in reducing all cause mortality. The primary endpoint did not show any statistically significant difference between Losartan and captopril in reducing all-cause mortality.
In both comparator-controlled (not placebo-controlled) clinical studies on patients with heart failure the tolerability of Losartan was superior to that of captopril, measured on the basis of a significantly lower rate of discontinuations of therapy on account of adverse events and a significantly lower frequency of cough.
An increased mortality was observed in ELITE II in the small subgroup (22% of all HF patients) taking beta-blockers at baseline.
Paediatric Population
The antihypertensive effect of Losartan was established in a clinical study involving 177 hypertensive paediatric patients 6 to 16 years of age with a body weight> 20 kg and a glomerular filtration rate> 30 ml/min/1.73 m². Patients who weighed>20kg to < 50 kg received either 2.5, 25 or 50 mg of losartan daily and patients who weighed> 50 kg received either 5, 50 or 100 mg of losartan daily. At the end of three weeks, losartan administration once daily lowered trough blood pressure in a dose-dependent manner.
Overall, there was a dose-response. The dose-response relationship became very obvious in the low dose group compared to the middle dose group (period I: -6.2 mmHg vs. -11.65 mmHg), but was attenuated when comparing the middle dose group with the high dose group (period I: -11.65 mmHg vs. -12.21 mmHg). The lowest doses studied, 2.5 mg and 5 mg, corresponding to an average daily dose of 0.07 mg/kg, did not appear to offer consistent antihypertensive efficacy.
These results were confirmed during period II of the study where patients were randomized to continue losartan or placebo, after three weeks of treatment. The difference in blood pressure increase as compared to placebo was largest in the middle dose group (6.70 mm Hg middle dose vs. 5.38 mmHg high dose). The rise in trough diastolic blood pressure was the same in patients receiving placebo and in those continuing losartan at the lowest dose in each group, again suggesting that the lowest dose in each group did not have significant antihypertensive effect.
Long-term effects of losartan on growth, puberty and general development have not been studied. The long-term efficacy of antihypertensive therapy with losartan in childhood to reduce cardiovascular morbidity and mortality has also not been established.
In hypertensive (N=60) and normotensive (N=246) children with proteinuria, the effect of losartan on proteinuria was evaluated in a 12-week placebo- and active-controlled (amlodipine) clinical study. Proteinuria was defined as urinary protein/creatinine ratio of
Overall, after 12 weeks of treatment, patients receiving losartan experienced a statistically significant reduction from baseline in proteinuria of 36% versus 1% increase in placebo/amlodipine group (p
Absorption
Following oral administration, losartan is well absorbed and undergoes first-pass metabolism, forming an active carboxylic acid metabolite and other inactive metabolites.
The systemic bioavailability of Losartan tablets is approx. 33%. Mean peak concentrations of losartan and its active metabolite are reached in 1 hour and in 3-4 hours, respectively.
Distribution
Both losartan and its active metabolite are
Biotransformation
About 14% of an intravenously or orally administered dose of losartan is converted to its active metabolite. Following oral and intravenous administration of 14C-labelled losartan potassium, circulating plasma radioactivity primarily is attributed to losartan and its active metabolite. Minimal conversion of losartan to its active metabolite was seen in about one percent of individuals studied.
In addition to the active metabolite, inactive metabolites are formed.
Elimination
Plasma clearance of losartan and its active metabolite is about 600 ml/minute and 50 ml/minute, respectively. Renal clearance of losartan and its active metabolite is about 74 ml/minute and 26 ml/minute, respectively. When losartan is administered orally, about 4% of the dose is excreted unchanged in the urine, and about 6% of the dose is excreted in the urine as active metabolite. The pharmacokinetics of losartan and its active metabolite are linear with oral losartan potassium doses up to 200 mg.
Following oral administration, plasma concentrations of losartan and its active metabolite decline polyexponentially with a terminal half-life of about 2 hours and 6-9 hours, respectively. During once-daily dosing with 100 mg, neither losartan nor its active metabolite accumulates significantly in plasma.
Both biliary and urinary excretion contribute to the elimination of losartan and its metabolites. Following an oral dose/intravenous administration of 14C-labeled losartan in man, about 35% / 43% of radioactivity is recovered in the urine and 58%/50% in the faeces.
Characteristics in patients
In elderly hypertensive patients the plasma concentrations of losartan and its active metabolite do not differ essentially from those found in young hypertensive patients.
In female hypertensive patients the plasma levels of losartan were up to twice as high as in male hypertensive patients, while the plasma levels of the active metabolite did not differ between men and women.
In patients with mild to moderate alcohol-induced hepatic cirrhosis, the plasma levels of losartan and its active metabolite after oral administration were respectively 5 and 1.7 times higher than in young male volunteers (see section 4.2 and 4.4).
Plasma concentrations of losartan are not altered in patients with creatinine clearance above 10 ml/minute. Compared to patients with normal renal function, the AUC for losartan is about two times higher in haemodialysis patients.
The plasma concentrations of the active metabolite are not altered in patients with renal impairment or in haemodialysis patients.
Neither losartan nor the active metabolite can be removed by haemodialysis.
Pharmacokinetics in paediatric patients
The pharmacokinetics of losartan have been investigated in 50 hypertensive paediatric patients> 1 month to < 16 years of age following once daily oral administration of approximately 0.54 to 0.77 mg/ kg of losartan (mean doses).
The results showed that the active metabolite is formed from losartan in all age groups. The results showed roughly similar pharmacokinetic parameters of losartan following oral administration in infants and toddlers, preschool children, school age children and adolescents. The pharmacokinetic parameters for the metabolite differed to a greater extent between the age groups. When comparing preschool children with adolescents these differences became statistically significant. Exposure in infants/toddlers was comparatively high.
Preclinical data reveal no special hazard for humans based on conventional studies of general pharmacology, genotoxicity and carcinogenic potential. In repeated dose toxicity studies, the administration of losartan induced a decrease in red blood cell parameters (erythrocytes, haemoglobin, haematocrit), a rise in urea-N in the serum and occasional rises in serum creatinine, a decrease in heart weight (without a histological correlate) and gastrointestinal changes (mucous membrane lesions, ulcers, erosions, haemorrhages). Like other substances that directly affect the renin-angiotensin system, losartan has been shown to induce adverse effects on late fetal development, resulting in fetal death and malformations.
