Trip-Tox, Effectiveness of Triptans Before and After Onabotulinumtoxin A Treatment in Chronic Migraine
Trip-tox Study. Analysis of the Efficacy and Satisfaction of Symptomatic Treatment With Triptans in Patients With Chronic Migraine Undergoing onabotulinumtoxinA Treatment
研究概览
详细说明
Hypothesis In patients with chronic migraine the efficacy of triptans, previously taken by the patient for the migraine attack, is better and more satisfactory after starting treatment with onabotulinumtoxinA.
Objectives To analyze the efficacy and satisfaction of the triptan usually taken by the patient with chronic migraine before starting preventive treatment with onabotulinumtoxinA, at 4 months, after two sessions of Botox, and at 7 months of treatment, after three sessions of Botox.
Sample size n=100 patients with chronic migraine in whom treatment with onabotulinumtoxinA is indicated. The indication for Botox treatment will be performed as usual and the patient will take his usual triptan if he has a migraine attack, so there is no therapeutic modification in this study that could involve any bioethical issue.
All patients signed the informed consent and the study was approved by the Comitè d'Ètica de la Investigació amb Medicaments (CEIm) de l'Hospital de la Santa Creu i Sant Pau.
