The buccal delivery is an attractive route to improve the clinical efficacy of ropinirole hydrochloride (RH) for the treatment of Parkinson and restless syndrome since this drug undergoes extensive first-pass effect, which has only 50% bioavailability after oral administration. The purpose of this study was to develop and optimize the formulation of fast disintegrating buccal effervescent tablets of RH using four types of superdisintegrants. The direct compression method was used to develop four different formulas containing RH using Kyron T-314, crospovidone, croscarmellose sodium, and sodium starch glycolate separately as a superdisintegrant. Sodium bicarbonate and citric acid were added to the formulations to produce effervescence, while sodium carbonate was used as a pH adjusting agent. All the prepared formulas were evaluated, in terms of weight variation, friability, content dose uniformity, hardness, disintegration, and dissolution test. The best formulation was selected for the subsequent study. The obtained results from pre-compression studies were in acceptable range according to British Pharmacopoeia. All formulas passed through the quality control test and significant difference (P < 0.05) was observed for the formula four compared to other formulas, due to the presence of Kyron T-314 as a superdisintegrant in formulation number 4. RH cloud be prepared as a buccal effervescent tablet and superdisintegrant provide fast disintegration of the tablet to exert rapid action.
