Prinzide

1 What is Prinzide?

Brand: Prinzide, Zestoretic

Generic: Lisinopril and hydrochlorothiazide

Prinzide is used to treat hypertension. Lisinopril is an ACE (angiotensin-converting enzyme) inhibitor. By inhibiting ACE it causes relaxation of vessels and also decreases absorption of water by the kidney, both helps in reducing pressure on vessels and thus increasing the supply of blood and oxygen to the heart.

Hydrochlorothiazide is a thiazide diuretic (water pill). It prevents absorption of salt in kidney and increases excretion of water in urine and so decreasing amount of water (fluids) in the body. It is available in a tablet form and only with your doctor’s prescription.
