Migraine treatments for complex patients are available. Gepants and OnabotulinumtoxinA are generally safe for those with cardiovascular, liver, or kidney disease, but more research is needed.
Area of Science:
- Neurology
- Pharmacology
- Internal Medicine
Background:
- Migraine management in patients with comorbidities presents unique challenges.
- Medically complex patients often have contraindications for standard migraine therapies.
Purpose of the Study:
- To review migraine treatment strategies for patients with renal, liver, and cardiovascular disease.
- To identify safe and effective acute and preventive therapies for complex migraine populations.
Main Methods:
- Literature review of current migraine treatment guidelines and studies.
- Analysis of drug safety profiles in patients with specific organ impairments.
Main Results:
- Gepants are recommended for acute therapy in cardiovascular disease; NSAIDs, ergotamines, and triptans are contraindicated.
- Frovatriptan, TCAs, valproic acid, and OnabotulinumtoxinA have favorable safety profiles in renal and/or hepatic disease.
- CGRP monoclonal antibodies show promise but require further investigation in complex populations.
Conclusions:
- Effective migraine treatment options exist for patients with cardiovascular, renal, and hepatic comorbidities.
- Further research is essential to establish definitive safety and dosing for newer migraine therapies in complex patient groups.
