Assignee:

PowderJect Research Limited - Oxford

International Classification:

C12Q 154

US Classification:

435 14, 435 4, 4352831, 435 25

Abstract:

An apparatus for sensing an analyte is described, wherein the apparatus includes an interface contact element that is used to establish an interface with a quantity of body fluid. The interface contact element is adapted to facilitate diffusion of a target analyte across the interface essentially free of net mass fluid transport. The quantity of body fluid is exposed to the interface contact element through micro-pathways. The apparatus can also include a sensing material adapted to sense the target analyte with at least one analytical method. Methods for using the apparatus in a non- or minimally invasive monitoring technique are also described.

International Classification:

A61K 31/4535
A61K 31/485

US Classification:

514282, 514326

Abstract:

The invention pertains to methods that include administering to a subject a transoral dosage form comprising a pharmaceutical carrier and sufentanil, and maintaining a mean pH ranging from about 3.5 to about 5.5 during a dosing period after administration of the transoral dosage form as determined using an in vitro donor media test. Related dosage forms are also disclosed. Also disclosed are transoral dosage forms and related methods, wherein a transoral dosage form may comprise: (1) about 5 to about 1000 micrograms of sufentanil; (2) about 50 micrograms to about 100 milligrams of naloxone; and (3) acidifying material in an amount sufficient to provide a mean pH ranging from about 3.5 to about 5.5 during a dosing period after administration of the transoral dosage form as determined using an in vitro donor media test; wherein the dosing period begins no earlier than about 1 minute after administration of the transoral dosage form, and ends no later than about 120 minutes after administration of the transoral dosage form.
