High Blood Pressure Medication

What is losartan

Losartan is from a class of medications known as Angiotensin II (AII) Receptor Blockers.  Stimulation of AII receptors cause blood vessels to contract and the body to retain sodium. Blocking this receptor allows the vessels to relax and the body to excrete excess sodium, than in turn decreases blood pressure.
