Abstract Objective: To prepare sustained release tablets of pseudoephedrine hydrochloride and determine its dissolution profile. Methods: HPMC was used to prepare the sustainedrelease tablets and investigate impact of viscosities of HPMC or the percentages of HPMC (K4M) in formulations on drug release. HPMC incorporated with Na3PO4 carbomer, NaCMC and eudragit L100-55 on drug release was also investigated. Results and Conclusions: The sustained release tablet can continuously release for 8h.
