Angitan

Losartan potassium 25 - 50mg Tab
  • Mode of action

    It is an angiotensin II receptor type 1 (AT₁) antagonist. It competitively inhibits the binding of angiotensin II to AT1 in many tissues including vascular smooth muscle and the adrenal glands. Thus inhibits the AT1-mediated vasoconstrictive and aldosterone-secreting effects and results in decreased vascular resistance and blood pressure.
