Products
Lisinopril is commercially available in tablet form as a monopreparation (Zestril, generic) and as a fixed combination with hydrochlorothiazide (Zestoretic, generic). It has been approved in many countries since 1989.
Structure and properties
Lisinopril (C21H31N3O5, Mr = 405.49 g/mol) is present in drugs as lisinopril dihydrate, a white crystalline powder that is soluble in water. It is not a prodrug and is a peptidomimetic and has approximately the structure of the tripeptide phenylalanine-lysine-proline.
Effects
Lisinopril (ATC C09AA03) has antihypertensive properties and unloads the heart (preload and afterload). The effects are due to inhibition of the formation of angiotensin II from angiotensin I by inhibition of angiotensin converting enzyme (ACE). Lisinopril thus abolishes the effects of antiogensin II.
