Development and validation of UV Spectrophotometric method for simultaneous equation of Aspirin and Omeprazole in tablet dosage form

Sandip S. Chaudhari and Swapnil D. Phalak

YOSPRALA is newly designed tablet which effective in cardiovascular as well as gastrointestinal protection due to its immediate release of Omeprazole (40 mg) and delayed release of Aspirin (81 mg) or (325 mg) dose strength. Yosprala was approved by USFDA in Sept 2016 for cardiovascular and cerebrovascular diseases.

Aspirin is an antiplatelet agent & Omeprazole is proton pump inhibitor therefore it is made to develop a new analytical method for Simultaneous estimation of Aspirin and Omeprazole using Mehtanol as a solvent on the basis of solubility. The maximum Absorption (λ max) of Aspirin and Omeprazole was found at 276 and 301 respectively. Linearity range for aspirin was given at 10-50 μg/ml with %RSD value 0.997 and Omeprazole was 2-10 μg/ml with %RSD value 0.997. The method was validated for precision and % RSD was found less than 2.0 for both aspirin and omeprazole. The proposed method was statistically validated for standard deviation, relative standard deviation, coefficient of variance and the results were within the range. Hence the above method was simple, cheap, cost effective, economical, and robust.
