  • METHOD OF TREATING SCHIZOPHRENIA WITH AN IMPLANTABLE DEVICE FOR LONG-TERM DELIVERY OF DRUGS
    Publication number: 20210205593
    Abstract: 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.
    Type: Application

  • Polyoxaester suspending vehicles for use with implantable delivery systems
    Patent number: 8114430
    Abstract: Liquid polyoxaester polymer materials are provided as suspending vehicles suitable for dispensing of pharmaceutically active agents, such as proteins, from delivery devices, for example, pump-driven dosage forms. Polyoxaesters are made from at least one diacid and at least one diol. Through the use of polyoxaesters virtually solvent-free pharmaceutical suspensions can be created.
