Abstract: Synthetic pulmonary surfactant compositions comprising dipalmitoyl phosphatidylcholine, phosphatidylglycerol, and essentially neutral lipid, and having essentially no 1-palmitoyl 2-oleoyl phosphatidylglycerol and essentially no palmitic acid are provided. Methods for treating respiratory disease are also provided comprising administering a therapeutically effective amount of a synthetic pulmonary surfactant comprising dipalmitoyl phosphatidylcholine, phosphatidylglycerol, and essentially neutral lipid, and having essentially no 1-palmitoyl 2-oleoyl phosphatidylglycerol and essentially no palmitic acid.

Abstract: A liquid composition in an osmotic drug delivery system and a dosage form in an osmotic drug delivery system is disclosed comprising an amphiphilic molecule, a non-aqueous liquid solvent, and a pharmaceutically active agent.

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 &agr;-(tetrahydrofuranyl)-&ohgr;-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.

Abstract: A controlled release pharmaceutical composition includes a biocompatible polymeric material, preferably polyethylene-vinyl acetate or poly(lactic-glucolic acid), having incorporated therein a soluble receptor capable of binding to its ligand and thus affecting the ligand's function. The soluble receptor is preferably the soluble form of TNF.alpha. receptor. Such compositions are for use in the treatment of disorders in which neutralization of the deleterious effects of TNF.alpha. is required.
