Rational Combination Therapy in Refractory Migraine

HEADACHE, Issue 6 2008
B. Lee Peterlin DO
Refractory migraine (RM) headaches pose important treatment challenges to the patients who live with them and the clinicians who try to treat them. Defined based on the lack of response to acute, preventive, and nonpharmacologic treatment, RM is often treated with a combination of treatments. Although combination therapy for RM has not been systematically studied in randomized trials, clinical experience suggests that a rational approach to RM treatment, utilizing a combination of treatments, may be effective where monotherapy has failed. In this article we briefly identify patient populations appropriate for more aggressive migraine prevention with combination therapy. We then discuss modifiable risk factors and comorbidities in migraine and then focus on the use of rational combination therapy, as well as the duration migraine preventatives should be considered for use. Future research is needed to evaluate the full potential of rational combination treatment as a strategy for treating and ultimately preventing RM. [source]

Olanzapine in the Treatment of Refractory Migraine and Chronic Daily Headache

HEADACHE, Issue 6 2002
Stephen D. Silberstein MD
Background.,Olanzapine, a thienobenzodiazepine, is a new "atypical" antipsychotic drug. Olanzapine's pharmacologic properties suggest it would be effective for headaches, and its propensity for inducing acute extrapyramidal reactions or tardive dyskinesia is relatively low. We thus decided to assess the value of olanzapine in the treatment of chronic refractory headache. Methods.,We reviewed the records of 50 patients with refractory headache who were treated with olanzapine for at least 3 months. All previously had failed treatment with at least four preventative medications. The daily dose of olanzapine varied from 2.5 to 35 mg; most patients (n = 19) received 5 mg or 10 mg (n = 17) a day. Results.,Treatment resulted in a statistically significant decrease in headache days relative to baseline, from 27.5 ± 4.9 before treatment to 21.1±10.7 after treatment (P < .001, Student t test). The difference in headache severity (0 to 10 scale) before treatment (8.7±1.6) and after treatment (2.2 ± 2.1) was also statistically significant (P < .001). Conclusion.,Olanzapine may be effective for patients with refractory headache, including those who have failed a number of other prophylactic agents. Olanzapine should receive particular consideration for patients with refractory headache who have mania, bipolar disorder, or psychotic depression or whose headaches previously responded to other neuroleptic medications.

An Open Pilot Study Assessing the Benefits of Quetiapine for the Prevention of Migraine Refractory to the Combination of Atenolol, Nortriptyline, and Flunarizine

PAIN MEDICINE, Issue 1 2010
Abouch V. Krymchantowski MD, FAHS
ABSTRACT Background., Migraine is a prevalent neurological disorder. Although prevention is the core of treatment for most, some patients are refractory to standard therapies. Accordingly, the aim of this study was to evaluate the use of Quetiapine (QTP) in the preventive treatment of refractory migraine, defined as previous unresponsiveness to the combination of atenolol, nortriptyline, and flunarizine. Methods., Thirty-four consecutive patients (30 women and 4 men) with migraine (ICHD-II), fewer than 15 days of headache per month, and not overusing symptomatic medications were studied. All participants had failed to the combination of atenolol (60 mg/day), nortriptyline (25 mg/day), and flunarizine (3 mg/day). Failure was defined as <50% reduction in attack frequency after 10 weeks of treatment. After other medications were discontinued, QTP was initiated at a single daily dose of 25 mg, and then titrated to 75 mg. After 10 weeks, headache frequency, consumption of rescue medications, and adverse events were analyzed. Results., Twenty-nine patients completed the study. Three patients withdrew and two were lost to follow-up. Among those who completed, 22 (75.9%; 64.7% of the intention-to-treat population) had greater than 50% headache reduction. The mean frequency of migraine days decreased from 10.2 to 6.2 per month. Use of rescue medications decreased from 2.3 to 1.2 days/week. Adverse events were reported by nine (31%) patients. Conclusions., Although limited by the open design, this study provides pilot data to support the use of QTP in the preventive treatment of refractory migraine. Controlled studies are necessary to confirm these observations. [source]

Management of patients with refractory migraine and PFO: Is MIST I Relevant?

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 1 2008
Jonathan Tobis MD
Abstract The results of the randomized clinical trial entitled: Migraine Intervention with Starflex Technology (MIST), produced surprising and disappointing results on the effect of PFO closure to decrease migraine headaches. There have been allegations of misrepresentation of the effectiveness of this device. These issues have significant implications in how randomized clinical trials are performed that will impact current and future planned trials of PFO closure to treat migraine headaches. © 2008 Wiley-Liss, Inc.
