Comparison of Propranolol, Flunarizine and Their Combination in Preventing Migraine in Adults in a Tertiary Care Hospital in Bangladesh

Migraine is a common and disabling neurological condition that affects quality of life, work productivity, and daily functioning. In Bangladesh, migraine is a major health problem, yet access to effective and affordable preventive treatments remains limited. Preventive (prophylactic) treatment is recommended for people who experience frequent migraine attacks in order to reduce the number, severity, and duration of headaches. Propranolol and flunarizine are two commonly used and relatively inexpensive medications for migraine prevention. Both drugs have been shown to reduce migraine frequency when used alone. However, some patients do not respond adequately to a single medication. Using a combination of drugs that work through different mechanisms may improve treatment effectiveness without significantly increasing side effects. There is limited local evidence comparing propranolol, flunarizine, and their combination in migraine prevention, particularly in the Bangladeshi population. This study is designed to compare the effectiveness and safety of propranolol alone, flunarizine alone, and a combination of propranolol and flunarizine in preventing episodic migraine in adults. The main hypothesis is that at least one of these treatment strategies, particularly combination therapy, may be more effective than the others in reducing migraine burden. This is an open-label, parallel-arm, randomized controlled trial conducted at Chittagong Medical College Hospital, Bangladesh. A total of 177 adult patients aged 18 to 55 years who are diagnosed with episodic migraine and experience four or more migraine attacks per month will be enrolled. Participants will be randomly assigned to one of three treatment groups: propranolol, flunarizine, or a combination of both medications. Treatment will be given for 12 weeks, with dose adjustments during the first week and follow-up visits at 6 and 12 weeks. The primary outcome of the study is the reduction in the number of monthly migraine days. Secondary outcomes include the proportion of patients achieving at least a 50% reduction in migraine days, changes in headache severity and duration, improvement in migraine-related disability (measured by the Migraine Disability Assessment Score), patient-reported treatment satisfaction, and the frequency of side effects. The results of this study are expected to provide important local evidence to guide clinicians in selecting effective and affordable migraine preventive treatments and to clarify whether combination therapy offers additional benefits over single-drug therapy in routine clinical practice.

Long-term Extension Study to Assess Adverse Events of Oral Atogepant Tablets in Pediatric Participants (6 to 17 Years of Age) With Migraine

A migraine is a moderate to severe headache on one side of the head. A migraine attack is a headache that may be accompanied by throbbing, nausea, vomiting, sensitivity to light and sound, or other symptoms. A number of treatments are available for adults with migraine but there are limited approved treatments available for participants less than 18 years of age. The main goal of the study is to evaluate the long-term safety and tolerability of atogepant in pediatric participants between the ages of 6 and 17 with migraine. Atogepant is a medicine currently approved to treat adults with migraine (0 to 14 migraine days per month) and is being studied in pediatric participants between the ages of 6 and 17 with a history of migraine. This is a Phase 3, open-label study of atogepant in participants with a history of migraine. Participants must have completed participation in another study of atogepant (lead-in study). Participants must have 4 to 14 migraine days and less than 15 headache days for episodic migraine, and \>= 15 headache days and \>= 8 migraine days for chronic migraine in the 4-week screening electronic diary (eDiary; similar to a smart phone). Around 650 participants will be enrolled in the study at approximately 100 sites worldwide. Atogepant is a tablet taken once a day by mouth. Participants between the ages of 12 and 17 will receive high dose atogepant for 52 Weeks. Participants between the ages of 6 and 11 will receive an atogepant dose determined in the lead-in study for 52 Weeks. There may be a bigger responsibility for participants in this study. Participants will attend regular visits during the study at a hospital or clinic. The effects of treatment will be checked by medical assessments, blood tests, checking for side effects, and completing questionnaires.

The Real-world Study of Rimegepant Treatment in Female Migraine Patients of China

The goal of this observational study is to learn about the effects and safety of Rimegepant in women, especially young and middle-aged women, who take Rimegepant to treat their migraine in the real world. Participants already taking Rimegepant (75mg QOD) as their regular preventive treatment of migraine for 12 weeks will be evaluated as the followings : 1. To evaluate the change from baseline in the mean number of migraine days per month during weeks 1-12 2. To evaluate the number of participants that have least a 50% reduction from baseline in the mean number of migraine days per month during weeks 1-12
