Absorbable polymers derived from alkylene oxalates are formulated with drugs and introduced into the body to provide a slow, sustained release of the drug over an extended period of time in accordance with the rate of absorption of the polymer. Polymers of alkylene oxalates, particularly wherein the alkylene moiety is C3 to C16, are biodegradable in animal tissue and absorb with minimal adverse tissue reaction. |
