    摘要: Pharmaceutical compositions that include a poorly water-soluble therapeutic compound, an aqueous solvent, an chelator/antioxidant, a buffer or buffer component, and a bulking agent. The pharmaceutical compositions can be orally ingested or administered parenterally. The pharmaceutical compositions can further be lyophilized to form a pharmaceutically acceptable cake that can be administered orally, e.g., as a solid oral dosage form; or reconstituted and administered parenterally, e.g. as a single i.v. bolus or iv infusion, or administered orally, e.g. as a drink solution.

    摘要: A method of liposome-based therapy for a mammalian subject is disclosed. The method uses liposomes and/or liposomes with outer surfaces that contain an affinity moiety effective to bind specifically to a biological surface at which the therapy is aimed, and a hydrophilic polymer coating. The hydrophilic polymer coating is made up of polymer chains covalently linked to surface lipid components. After a desired liposome biodistribution is achieved, the affinity agent binds to the target surface and helps internalize the liposomes.

    摘要: Methods for reducing or inhibiting the irreversible inactivation of water-soluble biologically active agents in biodegradable polymeric delivery systems which are designed to release such agents over a prolonged period of time, such as PLGA delivery systems are provided. The method comprises preparing PLGA delivery systems whose microclimate, i.e. the pores where the active agent resides, uniformly or homogenously maintain a pH of between 3 and 9, preferably between 4 and 8, more preferably between 5 and 7.5 during biodegradation. Depending on the size of the delivery system, and the initial bulk permeability of the polymer, this result is achieved by (a) incorporating a water-soluble carrier into the delivery system, (b) incorporating a select basic additive (or antacid) into the delivery system, (c) incorporating both a water soluble carrier and a select basic additive into the delivery system, (d) adding a pore forming molecule for increasing the rate of release of low molecular weight monomers and oligomers into the delivery system, (e) using a PLGA polymer with reduced glycolide content, i.e. PLGA with from 100% to 75% lactide and 0 to 25% glycolide) (f) using a microencapsulation method that yields a more extensive pore-network, e.g. oil-in-oil emulsion-solvent extraction as opposed to water-in-oil-in water-solvent evaporation method, and (g) combinations thereof.
