Abstract: Polymer and drug containing compositions and method of preparing such compositions are disclosed. The dispersed phase formulation has a polymer, a pharmaceutically or biologically active agent and a small fraction of low pKa acid additive. Stable, filter sterilizable, non-gelling solutions containing GnRH analogues at least at levels typically used in sustained release formulations and a method of increasing solubility of a high level of a GnRH analogue or a freeze-dried antgonist of GnRH in a polymer containing solution are also disclosed. The amount of the acid additive in the polymer solution is such that it is sufficient to increase the solubility of the high level of the GnRH analogue in the polymer solution without affecting the release characteristics of the microspheres prepared therefrom.

Abstract: Various embodiments of a method of preparing sustained release microparticles are described. In one embodiment, the method includes the steps of forming a dispersed phase of an active agent in a polymer and combining the dispersed phase with a continuous phase to form a microparticle dispersion. The method further includes the step of adding a measured amount of a dilution composition to the microparticle dispersion. It has been found herein that the various embodiments for preparing sustained release microparticles using various amounts of the dilution composition alters the release rate of the sustained microparticle for the specific active agent.

Abstract: Microspheres for releasing an octreotide compound without an initial time lag include a poly(D,L-lactide-co-glycolide) polymer (PLGA polymer) matrix having a ratio of lactide to glycolide ranging from 80:20 to 90:10 mol %. The polymer has a molecular weight ranging from about 6000 to 16000. The octreotide compound is dispersed in the polymer matrix. The microspheres can be made by forming a dispersed phase by combining the above polymer, dichloromethane, the octreotide compound, methanol and acetic acid. A target loading of the octreotide compound in the dispersed phase ranges from 7 to 12% by weight. Polyvinyl alcohol is dissolved in water to form a continuous phase. The dispersed phase is mixed in the continuous phase to form a microsphere suspension. The dichloromethane, acetic acid, methanol and polyvinyl alcohol are removed from the microsphere suspension. Residual dichloromethane and methanol are removed from the microspheres by washing.
