Ethacizine

General Information

Ethacizine Impurities and Ethacizine 

Daicel Pharma offers high-quality impurities for Ethacizine, an active pharmaceutical ingredient. The impurity, Mono-Desethyl Ethacizine, plays a vital role in assessing the purity, reliability, and safety of Ethacizine. Daicel Pharma also offers a customized synthesis of Ethacizine impurities to cater to client requirements, with worldwide delivery options available.

Ethacizine [CAS: 33414-33-4], a related compound to moracizine, belongs to the class Ic antiarrhythmic agents. Its primary use is in Russia and other Commonwealth of Independent States (CIS) countries. It manages ventricular and supraventricular arrhythmias that are severe or refractory, particularly when accompanied by underlying heart disease. Additionally, it treats refractory tachycardia associated with Wolff-Parkinson-White syndrome.

Ethacizine: Use and Commercial Availability  

Ethacizine, a Class Ic antiarrhythmic drug, treats recurrent sustained ventricular tachycardia (VT). Ethacizine is effective for treating VT in coronary artery disease patients and is vital in programmed electrical stimulation in VT management. However, more research is needed to determine Ethacizine’s effectiveness in other heart diseases.

Ethacizine Structure and Mechanism of Action

The chemical name of Ethacizine is Ethyl N-[10-[3-(diethylamino)-1-oxopropyl]-10H-phenothiazin-2-yl] carbamate. Its chemical formula is C₂₂H₂₇N₃O₃S, and its molecular weight is approximately 413.5 g/mol.

Ethacizine suppresses retrograde stimulus conduction along the atrioventricular node and helps prevent paroxysmal atrioventricular nodal tachycardia.

Ethacizine Impurities and Synthesis

Ethacizine impurities refer to the presence of unwanted substances or byproducts found in Ethacizine drugs. They arise during the synthesis¹ or manufacturing process of Ethacizine. The common Ethacizine impurities may include related compounds, residual solvents, degradation products, and those introduced during synthesis or formulation. They can affect the purity, stability, and overall quality of Ethacizine. Therefore, it is vital to closely monitor and control the levels of impurities to ensure the safety and efficacy of Ethacizine medications.

Daicel Pharma offers a comprehensive Certificate of Analysis (CoA) for the Ethacizine impurity standard, Mono-Desethyl Ethacizine. They generate from an analytical facility that complies with cGMP standards. The CoA provides a detailed characterization report with data obtained through techniques such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity analysis. We give additional data like 13C-DEPT upon request. Daicel Pharma synthesizes unknown Ethacizine impurities or degradation products, and labeled compounds, to evaluate the efficacy of generic Ethacizine. Ethacizine-D5, a deuterium-labeled Ethacizine standard, is available for bio-analytical research, including BA/BE studies. Every delivery has a complete characterization report.
