By blocking the formation of angiotensin II, fosinopril relaxes the arteries and veins and lowers blood pressure. ACE inhibitors inhibit ACE and block the formation of angiotensin II. ACE is an enzyme in blood which controls the formation of angiotensin II, a chemical that circulates in blood and causes constriction of arteries and veins. Fosinopril is used for treating high blood pressure. Constriction of arteries and veins elevates blood pressure.

ACE inhibitors are used for treating high blood pressure, heart failure and for preventing kidney failure due to high blood pressure and diabetes. Its blood pressure lowering effect can. This improves the output of blood from the heart. By reducing blood pressure, fosinopril also reduces the work that the heart must do to pump blood through the arteries and veins. The FDA approved fosinopril in May 1991. Tablets should be stored between 15 and 30 C (59- 86 F). Monopril Fosinopril is in a class of drugs called angiotensin converting enzyme (ACE) inhibitors.

Other ACE inhibitors include enalapril (Vasotec), quinapril (Accupril), captopril (Capoten), ramipril (Altace), benazepril (Lotensin), lisinopril (Zestril, Prinivil), moexipril (Univasc) and trandolapril (Mavik).
