[In Vitro]

Dronedarone (SR-33589) is a multichannel blocker for atrial fibrillation . It is a potent inhibitor of the acetylcholine-activated K+ current from atrial and sinoatrial nodal tissue, and inhibits the rapid delayed rectifier more potently than slow and inward rectifier K+ currents and inhibits L-type calcium current. Under whole-cell patch clamp, it blocks IKr (IC50=3 μM) and ICa-L (IC50=0.18 μM). The effects on ICa-L are use- and frequency-dependent. Dronedarone inhibits current carried by human ether-a-go-go gene (HERG)-expressing oocytes (analagous to IKr) with an IC50 of 9 μM[1]. In guinea pig ventricular myocytes, dronedarone exhibits a state dependent inhibition of the fast Na+ channel current with an IC50 of 0.7±0.1 μM, when the holding potential is −80 mV[2].

[In Vivo]

Dronedarone (Hydrochloride) reduces significantly the incidence of ventricular fibrillation (VF) from 80 to 30% (p < 0.05) at 3 mg/kg i.v. and eliminated VF and mortality at 10 mg/kg i.v. [3]. Dronedarone inhibited carotid artery thrombus formation in vivo. Thrombin- and collagen-induced platelet aggregation is impaired indronedarone-treated mice (P\0.05), and expression ofplasminogen activator inhibitor-1 (PAI1), an inhibitor of the fibrinolytic system, is reduced in the arterial wall[4].

[Animal admin]

Rats: Rats are anesthetized, artificially ventilated, and the thorax opened by a left thoracotomy. Ischemia is induced by left coronary artery ligation, and reperfusion is achieved (after a 5-min period of ischemia) in a separate group of rats by removing the ligature. Agents are given intravenously 5 min before occlusion or orally 4 h before study[3]. Mice: Twelve-week-old C57Bl/6 mice are divided into two groups: dronedarone (200 mg/kg body weight with a once daily oral gavage for 14 days) or control (1.4 % methylcellulose). Twenty-four hours after the last application, mice are anesthetized by intraperitoneal injection of 87 mg/kg sodium pentobarbital. Rose bengal is diluted to 12 mg/mL in phosphate-buffered saline and then injected into the tail vein at a concentration of 63 mg/kg[4].
