Description: Poly(DL-lactic acid) is a glassy material, occurring as white to golden-yellow pellets or granules.

Chemical Name: Poly[oxy(1-methyl-2-oxo-1,2-ethanediyl)]

Biodegradable material; coating agent; controlled-release agent.

• Poly(DL-lactic acid) is used in drug delivery systems in implants, injections, and oral solid dispersions. It is also used as a coating agent.

Incompatible with strong acids or alkaline materials.

Poly(DL-lactic acid) degrades to produce lactic acid, which is considered a well-tolerated nontoxic material. Several in vitro and in vivo studies demonstrated that poly(lactic acid) in general (including poly(DL-lactic acid)) is well tolerated and does not induce a significant immune response.(6–10) However, some studies have illustrated signs of a mild immune response.

Observe normal precautions appropriate to the circumstances and quantity of the material handled. Eye and skin protection are recommended. Handle under dry, inert conditions.

Aliphatic polyesters; lactic acid.
