Chlorpromazine HCl and Promethazine HCl are potent anti-emetic. The central antimuscarinic actions of antihistamines are probably responsible for their anti-emetic effects. Fast dissolving tablets of Chlorpromazine HCl and Promethazine HCl were prepared using five superdisintegrants viz; sodium starch glycolate, crospovidone, croscarmellose, L-HPC and pregelatinised starch. The tablets were evaluated for weight variation, hardness, friability, disintegration time (1 min), dissolution rate, content uniformity, and were found to be within standard limit. It was concluded that the fast...
