Migrend Uses, Dosage, Side Effects, Food Interaction and all others data.
Migrend is the difluorinated derivative of cinnarizine. It is a seletive calcium channel antagonist and has H1-receptor blocking action. By reducing excessive transmembrane influx of calcium Migrend prevents cellular calcium overlod. It does not interfere with normal cellular calcium homeostasis. Migrend also has some antihistaminic and sedative properties.
Migrend is a selective calcium entry blocker with calmodulin binding properties and histamine H1 blocking activity.

Uses
Migrend is used for
- Prophylaxis of classic (with aura) or common (without aura) migraine
- Symptomatic treatment of vestibular vertigo (due to a diagnosed functional disorder of the vestibular system).
- Peripheral Vascular Disease (PVD)
- Motion sickness
- Refractory epilepsy resistant to conventional antiepileptic therapy.
Migrend is also used to associated treatment for these conditions: Severe Migraine
How Migrend works
Migrend inhibits the influx of extracellular calcium through myocardial and vascular membrane pores by physically plugging the channel. The decrease in intracellular calcium inhibits the contractile processes of smooth muscle cells, causing dilation of the coronary and systemic arteries, increased oxygen delivery to the myocardial tissue, decreased total peripheral resistance, decreased systemic blood pressure, and decreased afterload.
Dosage
Migrend dosage
Migraine Prophylaxis:
- Starting Dose: 10 mg at night in patients less than 65 years of age and 5 mg daily in patients older than 65 years. If, during this treatment depressive, extrapyramidal or other unacceptable symptoms occur, administration should be discontinued. If, after 2 months of this initial treatment, no significant improvement is observed, the patient should be considered a non-responder and administration should be discontinued.
- Maintenance Treatment: If a patient is responding satisfactorily and if a maintenance treatment is needed, the dose should be decreased to 5 days treatment at the same daily dose with two successive medicine free days every week. Even if the prophylactic maintenance treatment is successful and well tolerated, it should be interrupted after 6 months and it should be re-initiated only if the patient relapses.
Peripheral Vascular disease: 10 mg twice daily, up to 30 mg per day if required.
Vertigo & motion sickness: 10-20 mg daily for adults and 5 mg daily for children (> 40 kg).
Epileptic seizure: 15-20 mg daily in adults and 5 to 10 mg daily for children as an add-on therapy
Side Effects
Migrend is well tolerated and seldom causes serious side effects. The main adverse effects experienced by the patients are as follows:
Central nervous system: Depression, drowsiness, sedation, and anxiety.
Gastrointestinal: Heart burn, nausea, emesis, dry mouth, gastralgia.
Miscellaneous: Weight gain, and/or increased appetite, asthenia, muscle aches, skin rash, and galactorrhea in female patients on oral contraceptives.
Toxicity
-Migrend should be used with care in patients with depression or those being prescribed other agents, such as phenothiazines, concurrently, which may cause extrapyramidal side-effects. -Acute overdosage has been reported and the observed symptoms were sedation, agitation and tachycardia. -Treatment of acute overdosage consists of charcoal administration, induction of emesis or gastric lavage, and supportive measures. No specific antidote is known.
Precaution
Since sedation or drowsiness occur in some patients during treatment with flunarizine hydrochloride, patients should be cautioned against activities which require alertness or rapid, precise responses (e.g. operating machinery or a motor vehicle) until the response to the drug has been determined.
Interaction
Galactorrhoea has been reported in few women on oral contraceptives within the first two months of Migrend treatment. Hepatic enzyme inducers such as Carbamazepine and Phenytoin may interact with flunarizine by increasing its metabolism. So an increase in dosage of flunarizine may be required.
Food Interaction
- Avoid alcohol.
- Take with or without food. The absorption is unaffected by food.
Elimination Route
85% following oral administration.
