| Popis: | What is known and objective Migraine is a common and costly neurological disorder that affects approximately 1 of every 7 people annually. Pharmacological therapy for prevention of migraine is warranted when patients experience at least 6 headache days, 4 headache days with at least some impairment or 3 headache days with severe impairment or requiring bed rest in a month. Levetiracetam is an antiepileptic drug that has the potential to be beneficial for migraine prophylaxis. The objective of this review was to assess the safety and efficacy of levetiracetam for migraine prophylaxis. Methods A systematic search was conducted in MEDLINE (1946-August 2017), EMBASE (1947-August 2017) and CENTRAL using the terms: migraine disorders, migraine, or headache and etiracetam or levetiracetam. Animal studies, case reports, abstracts, letters to the editor and those not written in English were excluded. Results and discussion Eleven articles were identified for inclusion. Of the studies included, 2 were retrospective chart reviews, 4 were randomized placebo- or active comparator-controlled trials, and the remaining 5 were prospective, open-label studies. All studies found a statistically significant decrease in headache frequency per month compared to baseline or placebo when used for treatment of episodic migraine (2.96-10.9 headache/mo decrease), and 57.9%-100% of patients had at least a 50% decrease in headache frequency from baseline. Significance was not consistently demonstrated in the prophylactic treatment of chronic migraine. The most common adverse effects noted included somnolence, dizziness and behavioural effects but generally did not require discontinuation. What is new and conclusion The studies included in this review indicate that levetiracetam is well-tolerated and may be an alternative treatment option for episodic migraine prophylaxis. Additional clinical evidence is necessary to establish the efficacy of levetiracetam for the prophylactic treatment of chronic migraine. |
