A Sustainable UPLC-UV Method for Quantification of Donepezil Hydrochloride in Biorelevant Media Applied to Dissolution Profile Comparison.

A Sustainable UPLC-UV Method for Quantification of Donepezil Hydrochloride in Biorelevant Media Applied to Dissolution Profile Comparison. Drug Dev Ind Pharm. 2020 Aug 18;:1-40 Authors: Campos DP, Silva-Barcellos NM, Marinho FDM, Barbosa GX, Lana VLVV, de Souza J Abstract Donepezil hydrochloride is one of the most prescribed anti-Alzheimer's drugs, despite being available for more than two decades, chromatographic methods for the quantification of the drug in biorelevant media that mimics pH physiological conditions in vivo (pH 1.2, 4.5, 6.8) are not available in the literature. These media are used in the dissolution test, an important tool, for registration and quality control of medicines. Considering the need for methods with this purpose, this work aimed to develop and validate a sustainable UPLC-UV method for quantification of donepezil hydrochloride in tablets, specifically on assay and dissolution profile, with reduced environmental impacts. The proposed method has a run time of 2 min and requires for each run, only 0.8 mL of solvents, providing excellent green analysis. The method proved to be selective, linear, precise, accurate, robust in the range of 2-14 µg/mL. Three products (reference, similar and generic) were analyzed and showed very rapid dissolution. The average content varied from 100.2 ± 0.6% to 109.5 ± 2.1%. Using Dissolution Efficiency (DE), the drug release profiles were compared in different bi...
