| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| Description | Dronedarone hydrochloride is a non-iodinated amiodarone derivative that inhibits Na+, K+ and Ca2+ currents.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 .05), and expression ofplasminogen activator inhibitor-1 (PAI1), an inhibitor of the fibrinolytic system, is reduced in the arterial wall[4].

Dronedarone HCL is an amiodarone analogue which has been shown an effective and promising treatment for Atrial fibrillation (AF) [1].
In vitro, dronedarone has been demonstrated to inhibit muscarinic acetylcholine receptor-operated K+ current IK(ACh) induced by carbachol or GTP-gamma-S with IC50 values of 10nm and <100nm, respectively, in cells isolated from guinea pig atria. Notably, dronedarone was 100-fold potent and selective over amiodarone in inhibiting IK(ACh) [1].
In vivo, dronedarone has shown to block arterial thrombus formation, decrease platelet aggregation and reduce plasminogen activator inhibitor-1 (PAI1) expression in C57Bl/6 mice [2].

Identification and characterization of stress degradation products of dronedarone hydrochloride employing LC-UV/PDA, LC-MS/TOF and MS(n) studies.[Pubmed:26547261]
J Pharm Biomed Anal. 2016 Jan 25;118:139-148.
Dronedarone HCl was subjected to forced decomposition conditions of hydrolysis (neutral, acidic and alkaline), oxidation, photolysis and thermal stress, as suggested in the ICH guideline Q1A(R2). The drug showed significant degradation under alkaline hydrolytic and alkaline photolytic conditions while it remained stable in neutral, acidic, thermal and oxidative conditions. In total, six degradation products (I-VI) were formed, which could be separated by chromatography on C18 (250 mm x 4.6 mm; 5 mu, Xterra) column using isocratic elution method. Detection wavelength was selected as 288 nm. Multi-stage (MS(n)) and MS/TOF accurate mass studies were carried out to establish the complete fragmentation pathway of the drug which in turn was utilized in characterization of the products. The degradation pathway of the drug leading to generation of products I-VI was postulated and this has not been reported so far.
