Background: Some angiotensin converting enzyme (ACE) inhibitors have previously been shown to be effective in migraine prophylaxis. The aim of this study was to evaluate whether Enalapril is effective in migraine prophylaxis.
Methods: In this randomized, double-blind, placebo-controlled clinical trial, the effects of 10 mg Enalapril given daily were compared with those of matched placebo in 40 migraineurs for 2 months.
