Single-Site Study of Naltrexone/Acetaminophen for the Acute Treatment of Migraine: A Phase 2 Randomized Trial

Description

* This two-stage clinical trial will assess a novel combination therapy for acute migraine. In Stage 1 (factorial), participants will receive the combination, each individual component, or placebo. In Stage 2 (dose-finding), they will test three doses of the combination. Before both stages, participants will complete a run-in period, documenting a migraine attack without study medication. They will then treat one migraine attack in each stage. * 4 visits * Requirements: Migraine Diagnosis. BMI below 34. Read, write, and speak English. No opioids, marijuana, benzodiazepines, or excessive alcohol.
