The present invention is directed to a sensor system for use with a blood characteristic measurement device such as a pulse oximeter, on areas of the body having low normal cutaneous blood flow and for monitoring a blood characteristic such as oxygen saturation and pulse rate of patients, preferably over an extended period of time. The sensor system includes (a) a transdermal device containing a blood perfusion-enhancing agent that is administered in a controlled amount to the skin of a human patient and (b) a skin surface sensor.

A removable cartridge that is used in combination with a liquid drug infusion apparatus that comprises a housing that defines an inlet and outlet and has a recess for receiving the cartridge, a confined flow passageway extending between the inlet and outlet, and a conduit extending from the outlet to the infusion site. The removable cartridge includes: a hollow shell that fits within the recess, is adapted to contain the liquid drug, and has an outlet that is adapted to communicate with the inlet of the housing and the drug contained within the shell; pressure means within the shell that maintains a constant, positive pressure on the drug; and lock means on the shell that engages the housing to reversibly lock the cartridge within the recess.

An improvement in liquid dispensers, especially those used to infuse liquid drugs into patients from an expansible elastomeric bladder of specific geometry and elastomeric properties, is disclosed. The improvement is in making the bladder from an elastomeric composition whose stress relaxation does not exceed 10%, and whose low frequency hysteresis does not exceed 10%.

Novel compositions, formulations and dosage forms comprising stabilized micronized opioid particles are disclosed. Exemplary opioids include oxycodone, oxymorphone, hydrocodone, and hydromorphone, including as free bases or as salts. Stabilized micronized opioid particles having a DV90 particle size distribution of less and or equal to 10μ or less than or equal to 20μ are disclosed. Methods for micronizing an opioid to provide stabilized micronized opioid particles are also disclosed.

Transdermal delivery systems for administering sufentanil through the skin are provided. The systems contain a sufficient amount of sufentanil to induce and maintain a constant state of analgesia when applied to a subject. The systems are characterized as having one or more features including a high degree of dosage form rate control over flux of sufentanil from the system, a high net flux of sufentanil from the system through the skin, lack of a permeation enhancer, an adhesive member demonstrating superior shear time, a low coefficient of variation in the net flux of sufentanil from the system, a high delivery efficiency, and a substantially constant steady state net flux of sufentanil from the system. Methods of using the transdermal delivery systems to administer a sufficient amount of sufentanil to induce and maintain analgesia for extended periods when applied to a subject are also provided.

Disclosed solid water permeable implants that include a water permeable polymer and an osmotically active drug formulation that comprises a drug; wherein the solid water permeable implant has a ratio R of bulk density of the solid water permeable implant to osmotic pressure of the drug formulation wherein R is greater than about 0.244 grams/milliliter-atm. Also disclosed are methods of making and using such solid water permeable implants.

The invention features a plug for use with a drug delivery device, wherein the plug defines an expansion control channel, which accommodates thermal expansion of a formulation in a reservoir of a drug delivery device, and an exit channel. In one embodiment, the plug comprises an inner plug member and an outer plug member, which members define an expansion control channel to facilitate release of entrapped air and to accommodate thermal expansion of formulation from the sealed drug reservoir. The plug further defines an exit channel, and may optionally further comprise a frit positioned within the flow pathway just prior to the delivery outlet, or both.
