Evaluation of the Efficacy of Diclofenac Potassium and Rimegepant for the Acute Treatment of Migraine

ClinConnect Summary

This clinical trial is looking at how effective two medications, diclofenac potassium and rimegepant, are for treating migraines. The main goal is to see if a lower dose of diclofenac (50 mg) can provide pain relief that is just as good as a higher dose of rimegepant (75 mg) within two hours of taking the medication. This study is open to adults aged 18 to 65 who have a history of migraines, either with or without aura (the warning signs that can occur before a migraine), and have had migraines for at least a year.

If you qualify and decide to participate, you will take one of the two medications when you have a migraine and then report your pain level after two hours. It’s important to note that there are specific health conditions and recent treatments that may prevent you from joining the study, such as having had migraines for less than a year, experiencing more than 12 headaches per month, or currently taking certain migraine medications. The trial is currently recruiting participants, so if you’re interested, it’s a good idea to talk to your doctor to see if you meet the eligibility criteria.
