TRANSDERMAL THERAPEUTIC SYSTEM (TTS) WITH FENTANYL AS ACTIVE SUBSTANCE Russian patent published in 2007 - IPC A61K31/4468 A61K9/70 A61L15/22

Abstract RU 2311908 C2

FIELD: medicine.

SUBSTANCE: the present innovation deals with applying transdermal therapeutic system (TTS) with fentanyl of fentanyl-similar derivatives as an active substance. For avoiding random (incorrect) overdosing due to uncontrolled release of active substance being the result of a lesion, the active substance is in microreservoirs full of liquid. If necessary, the layer with active substance can be supplied with a membrane. The system in question favors steady release of active substance.

EFFECT: higher efficiency.
