Core Tip

Core Tip: Metoclopramide may be used to treat people suffering from acute migraine. However, no comprehensive investigation on this issue has been recorded. We conducted an up-to-date systematic review and meta-analysis of the clinical efficacy of metoclopramide during an acute migraine attack. This study comprised 14 studies and found that metoclopramide was more effective than placebo in treating migraine at the emergency department. When compared to other medications, however, no substantial advantage was detected. More study is needed to enhance migraine therapy in acute care settings effectively.
