Cozaar Tablets

• to treat patients with high blood pressure (hypertension) including adults and children and adolescents 6- 18 years of age.
• to protect the kidney in hypertensive type 2 diabetic patients.
• to treat patients with chronic heart failure when therapy with specific medicines called angiotensin-converting-enzyme inhibitors (ACE inhibitors, medicine used to lower high blood pressure) is not considered suitable by your doctor. If your heart failure has been stabilised with an ACE inhibitor you should not be switched to losartan.
• in patients with high blood pressure and a thickening of the left ventricle.

How does it work?

• Cozaar belongs to a class of medicines known as angiotensin II receptor antagonists. Angiotensin II is a substance produced in your body which causes your blood vessels to narrow, thus increasing your blood pressure. Cozaar blocks the effect of angiotensin II so that the blood vessels relax, and your blood pressure is lowered.

When and how do I take it?

Cozaar can be taken with or without food. Swallow the tablets with a little water. If possible, take your daily dose at the same time each day, for example at breakfast time.

What’s the dose?

Adult Patients with High Blood Pressure:

• Treatment usually starts with 50 mg losartan (one tablet Cozaar 50 mg) once a day. The maximal blood pressure lowering effect should be reached 3-6 weeks after beginning treatment. In some patients the dose may later be increased to 100 mg losartan (two tablets Cozaar 50 mg) once daily.

Use in children and adolescents (6 to 18 years old):

• The recommended starting dose in patients who weigh between 20 and 50 kg is 0.7 mg of losartan per kg of body weight administered once a day (up to 25 mg of COZAAR). The doctor may increase the dose if blood pressure is not controlled.

Adult Patients with high blood pressure and type 2 diabetes:

• Treatment usually starts with 50 mg losartan (one tablet Cozaar 50 mg) once a day. The dose may later be increased to 100 mg losartan (two tablets Cozaar 50 mg) once daily depending on your blood pressure response.

Adult Patients with Heart Failure:

• Treatment usually starts with 12.5 mg losartan (one tablet Cozaar 12.5 mg) once a day.
• Generally, the dose should be increased weekly step-by-step (i.e., 12.5 mg daily during the first week, 25 mg daily during the second week, 50 mg daily during the third week) up to the usual maintenance dose of 50 mg losartan (one tablet Cozaar 50 mg) once daily, according to your condition.

Could it interact with other tablets?

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription or herbal medicines and natural products.

Take particular care if you are taking the following medicines while under treatment with Cozaar:

• other blood pressure lowering medicines as they may additionally reduce your blood pressure. Blood pressure may also be lowered by one of the following drugs/ class of drugs: tricyclic antidepressants, antipsychotics, baclofene, amifostine,
• medicines which retain potassium or may increase potassium levels (e.g. potassium supplements, potassium-containing salt substitutes or potassium-sparing medicines such as certain diuretics [amiloride, triamteren, spironolactone] or heparine),
• non-steroidal anti-inflammatory drugs such as indomethacin, including cox-2-inhibitors (medicines that reduce inflammation, and can be used to help relieve pain) as they may reduce the blood lowering effect of losartan.

If your kidney function is impaired, the concomitant use of these medicines may lead to a worsening of the kidney function.
Lithium containing medicines should not be taken in combination with losartan without close supervision by your doctor. Special precautionary measures (e.g. blood tests) may be appropriate.

What are the possible risks or side-effects?
