| Targets |
Flecainide HCl targets cardiac sodium channels (Nav1.5), the rapid component of the delayed rectifier potassium channel (IKr), and the cardiac ryanodine receptor (RyR2). By blocking sodium channels, it reduces the rate of phase 0 depolarization and slows conduction in the heart. By inhibiting RyR2, it reduces spontaneous calcium release from the sarcoplasmic reticulum, which is relevant in CPVT. Its multiple mechanisms contribute to its antiarrhythmic effects.
|
|---|---|
| ln Vitro |
In vitro, Flecainide HCl blocks cardiac sodium and potassium currents and inhibits RyR2-mediated calcium release. Specific IC₅₀ values for these targets are not provided in the available sources. Its effects on action potential duration have been characterized in isolated cardiac preparations.
|
| ln Vivo |
In vivo, Flecainide HCl is used clinically as an antiarrhythmic agent. It is effective in suppressing various cardiac arrhythmias, including ventricular and supraventricular tachyarrhythmias. It has been studied in the context of CPVT, where it reduces arrhythmic events. Its efficacy has been established in clinical use.
|
| Enzyme Assay |
A cell-free assay for Flecainide HCl would involve measuring its inhibition of sodium or potassium channel activity using patch-clamp techniques on isolated channels expressed in heterologous systems. Its inhibition of RyR2-mediated calcium release can be assessed using single-channel recordings or calcium flux assays with microsomal preparations. Specific IC₅₀ values are not provided.
|
| Cell Assay |
Cellular assays for Flecainide HCl typically involve patch-clamp electrophysiology on cardiac myocytes or cell lines expressing cardiac sodium or potassium channels. The compound's ability to block these channels is measured by assessing changes in ionic currents. Its effects on calcium handling can be assessed in cells expressing RyR2. Specific protocols are not detailed in the available sources.
|
| Animal Protocol |
In vivo animal experiments for Flecainide HCl are not described in the available sources. As a clinically used drug, its efficacy and safety have been established in human studies. Preclinical studies in animal models of arrhythmias likely contributed to its development, but specific protocols and data are not provided.
|
| ADME/Pharmacokinetics |
Flecainide HCl is an orally active compound. It is well absorbed after oral administration. Its half-life is approximately 12-27 hours in humans, allowing for twice-daily dosing. It is metabolized in the liver, and its pharmacokinetics are influenced by CYP2D6 genotype. Specific PK parameters are not provided in the available sources.
|
| Toxicity/Toxicokinetics |
Toxicity data for Flecainide HCl are not detailed in the available sources. As a clinically used drug, its safety profile is well established. Common adverse effects include dizziness, visual disturbances, and proarrhythmic effects. It is contraindicated in patients with structural heart disease due to the risk of proarrhythmia.

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
