摘要:
Multi-dose formulations for bortezomib are presented in which bortezomib has significantly improved stability. Especially preferred formulations include those in which bortezomib is in a liquid form suitable for injection, wherein the solvent system predominantly comprises propylene glycol. In other preferred aspects, bortezomib is present as a Lewis donor-acceptor complex with a hetero-bifunctional Lewis base.

The present invention provides a composition and prodrug for targeted drug delivery to the central nervous system of a patient. The inventive composition and prodrug include a pharmaceutically acceptable active agent and at least one protein selected from the group consisting of a fimbrial adhesin protein, a membrane protein, and combinations thereof. The inventive compositions and prodrugs of the present invention selectively target the blood-brain barrier and deliver hydrophilic and lipophilic active agents of varying sizes to the central nervous system.
摘要:
The present invention provides compositions comprising biologically-active somatotropin formulated for extended release and methods of preparing and methods of using the same. These compositions comprise somatotropin, at least a first bioavailability-enhancing constituent (BEC), and a substantially non-aqueous, hydrophobic excipient, and optionally a second BEC. The first BEC is typically a surfactant (preferably a non-ionic surfactant) or a cyclodextrin compound. The optional second BEC may comprise (i) amino acids or amino acid derivatives; (ii) hydroxamate derivatives; (iii) non-reducing carbohydrates; (iv) oxo-acid salts; or (v) a mixture of two or more compounds from within the foregoing classes (i)–(iv).

The present invention provides methods and compositions for delivery of taxanes in stable oil-in-water emulsion. The inventive emulsion formulation includes an oil phase, aqueous and emulsifier phases. The oil portion includes all or substantial amount of taxane, vegetable oil and medium chain triglycerides; aqueous phase includes an emulsion stabilizer; emulsifier phase reduces the surface tension between oil and aqueous phases to produce a stable oil-in-water emulsion. The inventive compositions produce minimal side effects upon administration.
摘要:
The present invention provides compositions which allow for the extended release and enhanced bioavailability of biologically-active polypeptides following parenteral delivery to an animal. More particularly, it concerns compositions comprising biologically-active somatotropin formulated for extended release, methods of preparing these compositions, and methods of using the same. These compositions comprise somatotropin, a bioavailability-enhancing constituent (BEC), and a substantially non-aqueous, hydrophobic excipient. The BEC may comprise (i) amino acids or amino acid derivatives, such as histidine-HCl; (ii) hydroxamate derivatives, such as histidine hydroxamate or suberohydroxamic acid; (iii) non-reducing carbohydrates, such as trehalose or trehalose octaacetate; (iv) oxo-acid salts, such as a mixture of monobasic and dibasic sodium phosphate; or (v) a mixture of two or more compounds from within the foregoing classes (i)–(iv).

摘要:
Solid dosage forms of bioactive materials for parenteral administration such as porcine or bovine somatotropin pellets intended for subcutaneous implantation to improve food production of farm animals are coated with polyvinyl alcohol to extend the release characteristics of the material. The polyvinyl alcohol preferably has a molecular weight of from about 20,000 to 100,000, a degree of hydrolysis of at least about 98%, and is applied from an aqueous solution by spray coating to form a continuous uniform covering 3 to 25 .mu.m PVA/mm.sup.2.
