ABSTRACT:
Absorbable copolyoxalate polymers having isomorphic sequences 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. The copolyoxalate polymers are derived from mixtures of cyclic and linear diols, each having the same number of carbon atoms. The polymers are biodegradable in animal tissue and absorb with minimal adverse tissue reaction.
