Perindopril 2mg/indapamide 0.625mg. Fixed low-dose combination.
Low-dose drug combinations have been proposed in International Guidelines for use in patients with hypertension. The fixed low-dose combination of perindopril 2mg with indapamide 0.625mg combines an angiotensin converting enzyme (ACE) inhibitor with a non-thiazide diuretic. Coadministration of perindopril and indapamide did not have any clinically significant effects on the pharmacokinetic profile of either agent in healthy volunteers. In experimental models of hypertension, perindopril/indapamide restored endothelial function, improved microvascular density, reduced left ventricular and aortic hypertrophy, and reversed renal end-organ damage. Once daily oral perindopril 2mg/indapamide 0.625mg normalised blood pressure (BP) in 83.6% of elderly patients with essential hypertension (diastolic BP was reduced to < or =90mm Hg) and 81.7% of those with isolated systolic hypertension (systolic BP was reduced to <160mm Hg) after approximately 1 year of treatment. BP normalisation was sustained in 79.8% of patients throughout the study. Fixed low-dose perindopril/indapamide had a tolerability profile similar to that of placebo in clinical trials; most adverse events were of mild to moderate severity. Coadministration of the 2 agents reduced the incidence of hypokalaemia seen with indapamide alone.
