The aim of this work is to develop and validate a dissolution test for ropinirole tablets based on in vivo data. The best dissolution conditions were USP apparatus 1, 500 ml of medium containing pH 4.0 deaerated citrate buffer at a speed of 50 rpm and detection was carried at 250 nm. The in vitro dissolution samples were analyzed and validated using HPLC method according to USP protocol. The method showed accuracy, precision, linearity and specificity within the acceptable range. The kinetics of dissolution was determined using model-dependent methods. The dissolution profiles were best described by Hixson–Crowell model.
