Drug Name: Cozaar (Losartan)
Drug Uses: Losartan is indicated for the treatment of hypertension. It may be used alone or in combination with other agents. It has less of an effect in black patients, similar to ACE inhibitors, such as captopril (Capoten), enalapril (Vasotec), and lisinopril (Zestril).
How Taken: Losartan may be given with or without food. Losartan is metabolized in the liver by cytochrome P450 enzymes to an active metabolite that is responsible for most of the drug activity. Reduction in dose by 50% is suggested in patients with impaired liver function.
Drug Class and Mechanism Losartan and its primary metabolite block the angiotensin receptor found in many tissues, primarily in vascular smooth muscle. Angiotensin, formed by the action of angiotensin converting enzyme (ACE), is a powerful chemical that causes blood vessel narrowing (vasoconstriction) which can lead to elevated blood pressure (hypertension).
Missed Dose Take the missed dose as soon as you remember. However, if it is almost time for the next dose, skip the missed dose and take only the next regularly scheduled dose. Do not take a double dose of this medication.
Storage Tablets should be stored at room temperature in a tightly closed, light resistant container.
