New migraine prevention drugs are emerging, with divalproex sodium recommended and topiramate showing promise. Further research is needed for other agents like riboflavin and gabapentin.
Area of Science:
- Neurology
- Pharmacology
Background:
- Established migraine prophylaxis drugs have unknown mechanisms of action.
- Migraine pathophysiology may involve cortical hyperexcitability and neurotransmitter imbalances.
- Research is identifying new agents for migraine prevention.
Purpose of the Study:
- To review recent literature on new agents for migraine prophylaxis.
- To identify potentially effective treatments for frequent, severe, and long-lasting migraine attacks.
Main Methods:
- Literature search of MEDLINE (1998-2001) and headache textbooks (2000-2001).
- Inclusion of controlled and uncontrolled clinical studies and abstracts.
- Search terms included: migraine, preventive, prophylactic, and treatment.
Main Results:
- Divalproex sodium is recommended for migraine prevention.
- Lamotrigine may help prevent migraine aura; topiramate is promising pending further trials.
- Riboflavin shows promise, but needs comparison with established drugs.
- Gabapentin, magnesium, lisinopril, and botulinum toxin A lack sufficient data.
- Tiagabine, levetiracetam, zonisamide, and petasites require controlled data for efficacy confirmation.
- Montelukast was effective in an open trial but not in a controlled trial.
Conclusions:
- Divalproex sodium is a recommended option for migraine prophylaxis.
- Several new agents show potential but require further rigorous clinical validation.
- Advances in neuroscience are expected to yield more effective and better-tolerated migraine treatments.
