Description
Generic Name
Flunarizine
Precaution
Flunarizine may lead to drowsiness which is aggravated by the simultaneous intake of alcohol or other central nervous system depressants. Patients should avoid driving motor vehicles or performing other potentially hazardous tasks where a loss of mental alertness may lead to accidents. Flunarizine should therefore be used with caution in such patients.
Hypersensitivity to Flunarizine. Flunarizine is contra-indicated in patients with a history of depressive illness, or with pre-existing symptoms of Parkinson's disease or other extrapyramidal disorders.
FDA has not yet classified the drug into a specified pregnancy category.
Mode of Action
Flunarizine has H1-receptor blocking action and calcium-channel blocking effect. It has also been used as an adjunct epileptic therapy for patients refractory to standard treatment regimens.
Interaction
Galactorrhea has been reported in few women on oral contraceptives within the first two months of Flunarizine treatment. Hepatic enzyme inducers such as carbamazepine and phenytoin increase the metabolism of Flunarizine. So an increase in dose of the drug may be required. Concomitant use of a calcium channel blocker and amiodarone has been reported to result in sinus arrest and atrioventricular block.
Pregnancy Category Note
The safety of Flunarizine for use in pregnancy and lactation has not been established.
