More information

  • Usage

    Losartan (Cozaar) is an oral medication used to treat high blood pressure. Losartan, like irbesartan, telmisartan and valsartan, belongs to a class of medications known as an angiotensin II receptor blockers (ARBs). Losartan (Cozaar) works by blocking the binding of angiotensin II to AT1 receptor in tissues, thereby impairing the aldosterone-secreting and vasoconstrictor effects of angiotensin II. Cozaar (losartan potassium) can be used alone or in combination with other antihypertensive agents such as diuretics to treat hypertension. Losartan may also help reduce the risk of stroke and left ventricular hypertrophy in specific classes of patients and help with the management of diabetic nephropathy.

  • Losartan – Side Effects

    Losartan, like similar medications, can cause side effects in some people. Side effects from losartan or Cozaar use include, but are not limited to, nausea, diarrhea, angioedema, fatigue, edema, abdominal pain, insomnia and cough. All questions regarding side effects associated with losartan or Cozaar use should be discussed with one’s pharmacist and medical provider before use.

  • Cost Information

    Generic losartan and the branded version, Cozaar, are affordable medications, costing under thirty cents per pill at most pharmacies. In addition, many insurance plans may cover the cost of the medication completely. At this time, however, losartan and Cozaar require a prescription and are not available over-the-counter (OTC) in the United States. Losartan coupons may also be available to reduce the cost for people paying out of pocket. Farmington Drugs & Medical Supplies takes pride in offering the most cost efficient services and prescriptions to our patients.

  • Dosage

    Losartan potassium, used in Cozaar, is a white to off-white crystalline powder. For dosing, available forms of Cozaar are orally administered Cozaar 25 mg tablets, Cozaar 50 mg tablets and Cozaar 100 mg tablets. After oral administration, losartan is partially converted into an active carboxylic acid metabolite and other inactive metabolites. The terminal half-life of losartan after oral administration is about two hours. After oral administration, less than 20% of the dose is converted to the active metabolite and losartan is excreted via the urine and the bile. Losartan and its metabolite bind extensively to proteins like albumin in the plasma. Cozaar may be administered with food or other hypertensive agents. Cozaar (losartan) tablets should be stored at 25° C.
