  • Patent number: 10813900
    Abstract: Methods for preparing sterilized baclofen solutions include adjusting the pH to below a desired pH, and steam sterilizing the solution with adjusted pH, which results in the solution having the desired pH. Such solutions may also have low concentrations of 4-CPP. Injectable baclofen solutions having greater than 2 mg/mL baclofen include between 5 mM and 25 mM of a phosphate or sulfate species. The solution has an ionic strength equivalent of about 1.5 M NaCl. The present application also provides baclofen formulations for use in treating spasticity, brain injury, cerebral palsy, spinal cord injury, cervical injury, multiple sclerosis, thoracic injury, or withdrawal symptoms.

  • Patent number: 9707338
    Abstract: An ambulatory infusion device includes a common module having a pump mechanism and a fluid flow path in communication with the pump mechanism. The device also includes a custom module operably coupleable to the common module. The custom module includes a reservoir for housing a liquid composition comprising a medicament and control electronics. The reservoir is configured to fluidly couple with the fluid flow path, and the control electronics are configured to electrically couple to the pump mechanism when the common module and the custom module are operably coupled. When the common module and the custom module are operably coupled, the pump mechanism is configured to drive the liquid composition from the reservoir to a patient via the fluid flow path, and the control electronics are configured to control the rate at which the pump mechanism drives the liquid composition.

  • Patent number: 9463889
    Abstract: Prefilled reservoir apparatuses for use in ambulatory infusion devices include a rigid top and a flexible bag that forms at least a portion of a reservoir containing a liquid medicament composition. The reservoir apparatuses include a septum assembly that includes a fluid flow path in communication with the reservoir and a self-sealing septum disposed in or over the fluid flow path. The septum is positioned and configured to be pierced by a cannula of a base of an infusion device when the reservoir apparatus is received by the base.
