20100209348 | METHODS FOR DETERMINING LIPOSOME BIOEQUIVALENCE - This invention provides methods for determining liposome bioequivalence between a generic drug product and a reference brand-name product. Specific methods for determining bioequivalence between doxorubicin hydrochloric acid (HCl) liposome injection product (Doxil®) and a generic pegylated liposome doxorubicin product are disclosed herein. | 08-19-2010 |
20110106006 | IMPLANTABLE DEVICE FOR LONG-TERM DELIVERY OF DRUGS - A device for sustained delivery of a poorly water soluble drug is described. A drug reservoir within the device, when in operation, contains an aqueous suspension of the drug mixed with a suspension of an excipient that, in one embodiment, generates acidic groups for a sustained period of time to maintain a desired pH in the aqueous suspension that in turn provides a constant concentration of a soluble form of the drug. | 05-05-2011 |
20110223233 | MICROFABRICATED NANOPORE DEVICE FOR SUSTAINED RELEASE OF THERAPEUTIC AGENT - A drug delivery device that includes a capsule for implantation into the body; the capsule further includes a reservoir for containing a substance such as a therapeutic agent, at least one port for allowing the substance to diffuse from or otherwise exit the reservoir, and a nanopore membrane in communication with the capsule at or near the exit port for controlling the rate of diffusion of the substance from the exit port. The device also includes an optional screen for providing structural stability to the nanopore membrane and for keeping the pores of the nanopore membrane clear. One embodiment of the drug delivery device includes an osmotic engine internal to the device for creating fluid flow through the device. | 09-15-2011 |
