ABSTRACT:
Erodible devices are disclosed for delivering a drug to an environment of use. The devices comprise a body sized and adapted for delivering the drug to the environment of use, which body comprises (1) a poly(orthoester) or a poly(orthocarbonate) having a repeating unit consisting of a hydrocarbon radical and a symmetrical dioxycarbon unit of the general formula: ##STR1## wherein R.sub.1 is a multivalent hydrocarbon radical, R.sub.2 and R.sub.3 are hydrocarbon radicals with at least one of the R.sub.2 or R.sub.3 bonded to the dioxycarbon through an oxygen covalent bond, (2) a beneficial drug, and (3) an erosion rate modifier. The devices are useful for delivering both locally and systemically acting drugs over a prolonged period of time. A composition of matter is also disclosed comprising the poly(orthoesters) or the poly(orthocarbonates) and an erosion rate modifier.
