Mefenidil has been reported to be a selective cerebral vasodilator. It significantly increased cerebral blood flow (without stimulation of O2 uptake) and lowered cerebral vascular resistance without having significant effects in other circulatory regions. Increase in cerebral blood flow is not mediated via the beta-adrenergic receptor as the effect was not blocked by propranolol. However, the clinical usefulness of mefenidil as a cerebral vasodilator may be limited by the accompanying arterial hypotension due to systemic vasodilation, which was most prominent in heart and gut.
