Abstract

The present invention provides an injectable composition for controlled release drug delivery and the process of making the same, where the composition comprises: a lactate based polymer selected from poly(lactide-co-glycolide) or poly(lactide) having a weight average molecular weight between 5,000 and 50,000 dalton, an acid number of less than 3 mgKOH/g and the content of residual lactide monomers in the lactate-based polymer of less than about 0.3% by weight; a pharmaceutically acceptable organic solvent; and a bioactive substance or a salt thereof selected from leuprolide, goserelin, triptorelin, and combinations thereof in the molecular structure that is capable of reacting with lactide monomer to form a conjugate; and where the composition reduces the formation of the conjugate.

Claims (7)

What is claimed:
1. A process for making an injectable composition for lled release drug delivery comprising: combining poly(lactide-co-glycolide) or poly(lactide) having a weight average molecular weight between 5,000 and 50,000 dalton, an acid number of less than 3 mgKOH/g and the content of residual lactide monomers in the poly(lactide-co-glycolide) or actide) of less than 0.3% by weight; with a pharmaceutically acceptable organic t; and a bioactive substance or a salt thereof that contains an amino acid serine in the molecular structure that is capable of reacting with lactide monomer to form a conjugate, wherein the bioactive substance is ed from the group consisting of leuprolide, lin, triptorelin, and combinations thereof; with the proviso that no acid additive is added in making the composition.
2. The process of claim 1 where the lactide in the poly(lactide-co-glycolide) or poly(lactide) is D-lactide, D,L-lactide, L,D-lactide, L-lactide, (R,R)-Lactide, lactide and meso-lactide or any combination thereof.
3. The process of claim 1 wherein the poly(lactide-co-glycolide) or poly(lactide) has the content of residual e monomers of less than 0.2% by weight.
4. The process of claim 1 wherein the poly(lactide-co-glycolide) or actide) has the content of residual lactide monomers of less than 0.1% by weight.
5. The process of claim 1 wherein the poly(lactide-co-glycolide) or poly(lactide) has an acid number of less than 2 mgKOH/g.
6. The process of claim 1, wherein the poly(lactide-co-glycolide) or poly(lactide) is ctide.
7. The process of claim 1, wherein the poly(lactide-co-glycolide) or poly(lactide) is poly(lactide-co-glycolide) having the ratio of lactide/glycolide from
