  • Unit-dose combination composition for the simultaneous delivery of a short-acting and a long-acting oral hypoglycemic agent
    Publication number: 20030224046
    Abstract: A stable unit-dose combination composition for the simultaneous delivery of a short-acting oral hypoglycemic biologically active agent (such as, for example, repaglinide or nateglinide), and a long-acting oral hypoglycemic biologically active agent (such as, for example, metformin). Such a composition can be used for the treatment of non-insulin dependent diabetes mellitus (NIDDM) and the improvement of glycemic control.

  • Novel in-situ forming controlled release microcarrier delivery system
    Publication number: 20030049320
    Abstract: A ready-to use, stable, gelled polymer droplet-in-oil dispersion is described which helps in in-situ formation of a multitude of small solid, semisolid, or gelled microcarriers. The dispersion is placed into a body in a semisolid form and cures to form the delivery system in-situ. The process for making such a dispersion comprises the steps of (i) dissolving a polymer in a biocompatible solvent at an elevated temperature to form a polymer solution, (ii) preparing a second oil phase solution of a biocompatible oil and a biocompatible emulsifier at an elevated temperature, (iii) mixing the polymer solution with the oil phase solution at an elevated temperature and subsequently cooling to refrigeration temperature. Placing the gelled dispersion within a body produces the microcarrier delivery system in-situ.
