Abstract
The invention discloses a composition having a mixture of a pharmaceutically, medically or veterinarily acceptable polymer, preferable a poly (lactic-co-glycolic acid) copolymer (PLGA) containing between about 10 and 100 wt. % lactic acid (LA) units, preferably between about 50 and 90 wt. % LA units, and .alpha.-(tetrahydrofuranyl)-.omega.-hydroxypoly(oxy-1,2-ethandiyl) (glycofurol). Methods of forming solid implants in situ in an animal body, said implants optionally comprising a drug or other biologically active agent, as well as the use of the compositions of the invention in the treatment of animal bodies, are also disclosed.
