Description

Stugeron CAS NO 298-57-7 is a high-purity pharmaceutical active ingredient, chemically known as cinnarizine. This compound is a selective calcium channel blocker with antihistaminic properties, making it a critical intermediate for the production of specialized medications. It is primarily utilized by pharmaceutical manufacturers and research institutions developing treatments for vestibular disorders, motion sickness, and peripheral vascular diseases.

Application

• Pharmaceutical Active Ingredient (API): Primary use in the formulation of anti-vertigo and anti-emetic medications.
• Vestibular Disorder Treatment: Key component in drugs for Ménière's disease and other balance-related conditions.
• Motion Sickness Prevention: Used in prophylactic treatments for travel sickness.
• Peripheral Vasodilator: Employed in formulations aimed at improving blood circulation.
• Research & Development: Serves as a reference standard and building block in neurological and cardiovascular pharmacological research.
• Generic Drug Manufacturing: Essential for producing cost-effective generic versions of branded cinnarizine-based therapeutics.

Quality Control

Our Stugeron (Cinnarizine) is manufactured under strict quality management systems. It is typically supplied to meet BP (British Pharmacopoeia) and USP (United States Pharmacopeia) monograph standards, ensuring identity, purity, strength, and composition. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing all critical quality attributes. We ensure full traceability and compliance with cGMP guidelines for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
