Mexiletine hydrochloride

Catalog No. T1046Cas No. 5370-01-4
Alias Mexiletine HCl, KOE-1173 (hydrochloride), KO1173

Mexiletine hydrochloride (KOE-1173 hydrochloride) is a voltage-gated sodium channel blocker and a Class IB antiarrhythmic drug. Mexiletine hydrochloride exerts antiarrhythmic effects by inhibiting sodium current in myocardial cells, thereby reducing the rise rate of cardiac action potential (phase 0) and reducing the automaticity of Purkinje fibers.

Product Introduction

Bioactivity
Description
Mexiletine hydrochloride (KOE-1173 hydrochloride) is a voltage-gated sodium channel blocker and a Class IB antiarrhythmic drug. Mexiletine hydrochloride exerts antiarrhythmic effects by inhibiting sodium current in myocardial cells, thereby reducing the rise rate of cardiac action potential (phase 0) and reducing the automaticity of Purkinje fibers.
In vitro
Mexiletine shortened the cardiac Purkinje fiber effective response period (ERP) less than the action potential duration (APD), resulting in higher ERP/APD ratios.Mexiletine had no significant effect on atrioventricular conduction velocity, resting membrane potential, sinus node autoregulation, systolic arterial pressure, left ventricular function, or QRS or QT intervals. Mexiletine inhibits the inward flow of sodium ions through inhibition of sodium channels (requiring pulse initiation and conduction), which in turn reduces the rate of action potential elevation.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
