Abstract

Objectives: To evaluate the stability of Verapamil hydrochloride (VER.HCl) 120 mg sustained release capsules using real-time stability testing and accelerated aging stability testing according to FDA and Asean guidelines. Methods: Quantification of VER.HCl by ultraviolet absorption spectroscopy and HPLC; evaluate the solubility of VER.HCl 120mg sustained-release capsules according to the method in USP 41; evaluate the stability of VER.HCl 120mg sustained-release capsules under real condition and accelerated aging condition (temperature 40±1oC, humidity 75%); The evaluation parameters included: pellet appearance, VER.HCl content and solubility. Results: During 18 months of storage in real condition and 6 months of storage in accelerated aging condition, the quality parameters (appearance, solubility, content) of the VER.HCl 120mg sustained-release capsules were almost constant. Conclusion: After 18 months of storage in real condition and 6 months under accelerated aging condition, the quality parameters of extended-release VER.HCl 120mg capsules were stable and passed in-house specification of product.
