Three matrix excipients namely: Hydroxypropylmethylcellulose (HPMC), sodium carboxymethyl cellulose (NaCMC) and egg albumin (EA) were utilized for the preparation of controlled release matrix tablets containing 200 mg of aminophylline. The prepared tablets were evaluated with respect to physical parameters and dissolution rate. All formulations showed acceptable physical parameters. The release rate was variable depending on the composition of the matrix tablet. There was no significant difference between the dissolution rates of the matrix tablets prepared with HPMC or EA. The lowest release rate was observed in case of the matrix tablets prepared using NaCMC either alone or in combination with either HPMC or EA. The dissolution data of the drug from most matrix tablets formulation were fitted to Higuchi diffusion model.
