This drug Lozartan Plus Teva tablets belongs to the group of combined drugs – type II angiotensin receptor antagonists, based on losartan potassium and hydrochlorothiazide. The components mutually complement and enhance the effectiveness of each of them, to a greater extent than taken separately.
Losartan potassium is a vasoconstrictor, an active hormone related to the renin-angiotensive system. Angiotensin II is able to bind to the AT1 receptor found in various tissues of the body. Particularly in the smooth muscle of the blood vessels, which are part of the adrenal glands, kidneys and heart muscle. Promotes the proliferation of smooth muscle cells.
This hormone also has the property of detecting various biological reactions, including the reaction of vasoconstriction and the release of the hormone aldosterone, which is the main mineralocorticosteroid hormone of the adrenal cortex.
Losartan is able to selectively bond with the AT1 receptor, at the same time not bind or block other hormone receptors and ion channels. Also, this hormone does not have the ability to inhibit the ACE enzyme that promotes the breakdown of bradykinin.
Hydrochlorothiazide is a thiazide diuretic that increases the level of uric acid in the blood. Taking these drugs in combination causes a decrease in the hyperuricemia reaction caused by a diuretic.
This drug Lozartan Plus Teva tablets is used to treat hypertension in patients in whom effective blood pressure control is not ensured with losartan alone or hydrochlorothiazide alone.
