Abstract
A sustained release pharmaceutical composition in table-t form comprises an effective amount of an orallyactive therapeutic agent, 0.8 to 1. 6% by weight of a release controlling agent and 1.0 to 7.5% by weight of an erosion promoting agent, the relative amounts of the components being such that a criticality factor calculated according to equation I lies in the range 20 to 450. Equation 1 is <IMG> I wherein CF is the criticality factor, CA is the. amount of therapeutic agent per tablet in milligrams divided by the amount of release controlling agent per tablet in milligrams and CS is the amount of erosion promoting agent per tablet in milligrams divided by the amount of release controlling agent per-tablet in milligrams, Suitable therapeutic agents include acetylsalicylic acid, ibuprofen and flurbiprofen. A preferred release controlling agent is cellulose acetate phthalate and a preferred erosion promoting agent is corn starch.
