Several oral "vasoactive" drugs claim to increase walking capacity in patients with intermittent claudication (IC). Naftidrofuryl, cilostazol, buflomedil, and pentoxifylline are the most studied molecules. Although spanning several decades, several studies underlying these claims were not properly designed, underpowered or showed clinically doubtful outcomes. The evidence for these "vasoactive" drugs has always been received with scepticism, creating the need for systematic reviews and metaanalyses. This brief review discusses the benefit-risk assessment of vasoactive drugs, by applying a systematic review to evaluate randomized, placebo-controlled trials.
