Effectiveness and Safety of Pharmacologic Therapies for Migraine in the Emergency Department: A Systematic Review and Bayesian Network Meta-analysis
Abstract
STUDY OBJECTIVE
We performed a systematic review and Bayesian network meta-analysis to determine which pharmacologic therapies are relatively more effective and safer for migraine in adult patients who present to the emergency department (ED).
METHODS
We searched MEDLINE, Embase, and Web of Science from inception to February 9, 2024. Eligible studies were randomized controlled trials that enrolled adult participants presenting to ED with migraine and compared one pharmacologic therapy to another or placebo. Outcomes were as follows: 1) adequate pain relief at 2 hours, 2) change in pain intensity at 1 hour, 3) need for rescue drug at 2 hours, and 4) significant adverse reaction. We extracted data according to PRISMA-network meta-analysis and appraised trials using Cochrane RoB 2. For dichotomous outcomes, we performed Bayesian network meta-analysis to calculate odds ratios with 95% credible intervals; for continuous outcomes, we performed frequentist network meta-analysis to calculate mean differences with 95% confidence intervals. We assessed confidence using Confidence in Network Meta-analysis. We used Surface under the cumulative ranking curve (SUCRA) to rank agents.
RESULTS
Chlorpromazine intravenous (IV)/intramuscular (IM) (SUCRA=87.3%) was most likely to be superior for "adequate pain relief at 2 hours" (24 trials; n=2,361); metoclopramide IV-ibuprofen IV (SUCRA=94.6%) was most likely to be superior for "need for rescue drug" (not needing rescue drug) at 2 hours (27…
