Fixed combination verapamil SR/trandolapril

Verapamil sustained-release (SR)/trandolapril is a combination of a phenylalkylamine calcium antagonist and an angiotensin converting enzyme inhibitor for the management of essential hypertension. Verapamil SR/trandolapril does not adversely influence glucose, insulin or lipid parameters in patients with mild to moderate essential hypertension and type 2 (non-insulin-dependent) diabetes mellitus with or without elevated cholesterol and/or triglyceride levels. Verapamil SR/trandolapril reduces proteinuria to a greater extent than the individual components in patients with diabetic or non-diabetic proteinuria. The antihypertensive efficacy of once daily verapamil SR/trandolapril (180/1 or 180/2mg) for 8 weeks or 6 months is similar to that of atenolol/chlorthalidone (100/25 mg) and lisinopril/hydrochlorothiazide (20/12.5mg), and was at least as good as that of metoprolol/hydrochlorothiazide (100/12.5mg), in a small trial. The reduction ill sitting or supine diastolic and systolic blood pressure is greater after-verapamil SR/trandolapril (180/2 to 240/4mg) than after monotherapy with verapamil SR (180 and 240 mg/day) or trandolapril (2 to 8 mg/day), Fewer cardiac events occurred after verapamil SR/trandolapril (240/1 to 360/2 mg/day) than after trandolapril (1 to 2 mg/day) in postmyocardial infarction patients with congestive heart failure. The incidence of adverse events after verapamil SR/trandolapril is similar to that of comparator drugs and the individual components of the combination.
