These are Losartan potassium and Hydrochlorothiazide. Losartan belongs
to a group of medicines known as angiotensin-ll receptor antagonists.
Angiotensin II is a chemical occurring in the body, which tightens your blood
vessels making it harder for the blood to pass through them and causing
your blood pressure to increase.
