Racecadotril is an anti-diarrheal drug. Waters Alliance e2695 with PDA detector (2998) Zorbax SB C18 column (150 x 4.6 mm, 3.5 μm) (Isocratic mode) was used for the quantification of Racecadotril. A mixture of water and Acetonitrile (50:50) was used as diluent and the injection volume was 20 μl. The flow rate was 1.0mL/min (Detection wave length 230 nm). Linearity was evaluated in the concentration range 1–360 μg/ml with regression equation y = 14710 x+9958.9(Correlation coefficient R2 = 0.9996). The LOD and LOQ were found to be 0.2942 μg/mL and 0.9694 μg/mL respectively. Forced degradation studies were conducted for Racecadotril capsules and method validation was performed as per ICH guidelines.
