Qsartan Tab 25mg containing losartan potassium offers a valuable solution for individuals seeking to regulate their blood pressure or manage related cardiovascular conditions. The active ingredient, losartan potassium, plays a vital role in Qsartan Tab 25mg. It belongs to a class of medications called angiotensin II receptor blockers (ARBs). Losartan potassium functions by selectively blocking the action of angiotensin II, a substance in the body that causes blood vessels to narrow and promotes the release of aldosterone, a hormone that increases salt and water retention. By inhibiting angiotensin II, losartan potassium helps relax and widen blood vessels, reducing blood pressure and improving blood flow.
