    摘要: A method is provided for making an oral dosage form of a pharmaceutical agent which includes the steps of (a) providing particles which include a pharmaceutical agent; (b) blending the particles with particles of a pre-processed excipient to form a primary blend, wherein the pre-processed excipient is prepared by (i) dissolving a bulking agent (e.g., a sugar) and at least one non-friable excipient (e.g., a waxy or liquid surfactant) in a solvent to form an excipient solution, and (ii) removing the solvent from the excipient solution to form the pre-processed excipient in dry powder form; (c) milling the primary blend to form a milled pharmaceutical formulation blend that includes microparticles or nanoparticles of the pharmaceutical agent; and (d) processing the milled pharmaceutical formulation blend into a solid oral dosage form or liquid suspension for oral administration. The process yields formulations having improved wettability or dispersibility.

    摘要: A medical device having a coating of cell adhesion polypeptides to enhance endothelial cell adhesion onto the medical device. The cell adhesion polypeptides may be any of the proteins of the extracellular matrix which are known to play a role in cell adhesion or derivative peptides such as RGD or YIGSR. The polypeptides may be incorporated into the backbone of a polymer such as polyurethane, or grafted onto a polymer such polybisphosphonate. The polypeptides may also be carried on antibodies or displayed on bacteriophages. The polypeptides may also be modified to have adhesive amino acid sequences. In certain embodiments, the medical device further comprises a temporary barrier that protects the polypeptides from biofouling. The temporary barrier may be formed of a biodegradable polymer and be constructed as a coating over the polypeptides or as a plurality of micelles encapsulating the polypeptides. In certain embodiments, the polypeptides may be coated onto the medical device in such a manner as to form a monolayer of the polypeptides.
