Patent ID: 8470359

Claim:
A flowable composition for a controlled release formulation comprising an organic solvent, a medicament and a polymer of Formula HO—(P)—C(═O)O—R a —O(O═)C—(P)—OH wherein: R a is an alkane diradical comprising about 4 to about 8 carbons and is a residue of an alkane diol, P is a polymeric segment of repeating units of lactide, lactic, co(lactide-glycolide) or co(lactic-glycolic) moieties, the polymer is substantially insoluble in water and body fluid, the polymer has substantially no titratable carboxylic acid groups, and the polymer has a weight average molecular weight from about 10 kD to about 50 kD, and the polymer in neat form is a solid at ambient temperature, the organic solvent is a polar, aprotic organic solvent having at least some water solubility.
