The effectiveness of combined oral lysine acetylsalicylate and metoclopramide (Migpriv) in the treatment of migraine attacks. Comparison with placebo and oral sumatriptan

Abstract

In two, double-blind, randomised, clinical, trials (RCTs), oral lysine acetylsalicylate (1620 mg, equivalent to 900 mg aspirin) combined with metoclopramide (10 mg) (LAS + MTC) was compared with placebo, and with oral sumatriptan (100 mg) in one of these RCTs. In both RCTs the LAS + MTC combination was superior to placebo with therapeutic gains (percentage relief after active treatment minus percentage relief after placebo) of 30% and 31% for the first treated attack. These therapeutic gains are in the same range as those found for 100 mg oral sumatriptan, and in the comparative RCT the LAS + MTC combination was quite comparable to 100 mg sumatriptan, with success rates for the first attack of 57% and 53%, respectively.
