Dược Lực Học :
Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 blocking activity.
Cơ Chế Tác Dụng :
Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 blocking activity. It is effective in the prophylaxis of migraine, occlusive peripheral vascular disease, vertigo of central and peripheral origin, and as an adjuvant in the therapy of epilepsy.
Flunarizine 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.
Dược Động Học :
▧ Absorption :
85% following oral administration.
▧ Protein binding :
99% bound to plasma proteins
▧ Metabolism :
Hepatic, to two metabolites via N-dealylation and hydroxylation.
▧ Half Life :
18 days
Độc Tính :
-Flunarizine 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.
Chỉ Định :
Used in the prophylaxis of migraine, occlusive peripheral vascular disease, vertigo of central and peripheral origin, and as an adjuvant in the therapy of epilepsy.
Tương Tác Thuốc :
-
Triprolidine
The CNS depressants, Triprolidine and Flunarizine, may increase adverse/toxic effects due to additivity. Monitor for increased CNS depressant effects during concomitant therapy.
