Filed:

Aug 3, 1999

Appl. No.:

9/368014

Inventors:

Ronald LaPrade - Miami FL
John J. Wick - Miami FL

Assignee:

Noven Pharmaceuticals, Inc. - Miami FL

International Classification:

A61F 1302

US Classification:

424448

Abstract:

A patch applicator for easy application of a transdermal patch is disclosed, wherein the applicator is especially suitable for a small transdermal patch of size 20 cm. sup. 2 or less. The patch applicator includes a rigid release liner and a flexible transdermal patch releasably attached to the release liner. The release liner has a first and second poritons separated by a slit, and pulltabs affixed to the portions. The pulltabs can extend beyond an end margin of the transdermal patch, and preferably extend outwardly at an acute angle for use, so that a patch user may easily grasp the pulltabs and remove a first portion of the release liner from the patch. The patch is then applied to the skin or mucosa, followed by removal of the second portion and final application of the patch. The patch applicator reduces loss in manufacturing yield, and especially benefits the elderly population.

US Classification:

424448

Abstract:

A patch applicator for easy application of a transdermal patch, especially a small transdermal patch of size 20 cm. sup. 2 or less. The patch applicator includes a bottom release liner, a transdermal patch releaseably attached to the bottom release liner, and a top release liner releasably attached to the transdermal patch. The top release liner has a first tab which extends beyond an end margin of the transdermal patch, so that a patch user may easily grasp the tab and remove the top release liner and patch from the lower release liner. The patch is then applied to the skin or mucosa A second tab of the top release liner preferably also extends beyond an end margin of the patch so that the top release liner may be easily removed from the patch after the patch has been applied to the skin or mucosa. Alternatively, the first and second tabs are removed from the patch by peeling back the tabs from a slit between the tabs. The first and second tabs are differently and distinctly marked to aid the patch user in applying the patch.

International Classification:

A61F 1302

US Classification:

424448

Abstract:

Devices for the controlled release of an active agent to the skin or mucosa of a host are disclosed, which devices are laminates of a backing layer and a monolithic carrier layer formed from a melt blend of an active ingredient with a thermoplastic matrix polymer without first dissolving or suspending the polymer or active ingredient in a solvent therefor, so that the carrier layer is substantially free of residual solvent, wherein the thermoplastic matrix polymer has a melt temperature between about 170. degree. C. and about 200. degree. C. and is selected from polyether block amides, ethylene methacrylic acid copolymers, ethylene acrylic acid copolymers, copolymers of polyether prepolymers with polybutylene terephthalate, copolymers of polyether prepolymers with polyisobutylene terephthalate and polyether polyurethanes, the active ingredient is heat stable at the melt temperature of the matrix polymer and is selected from active agents, active agent enhancers and mixtures thereof, and the laminate is provided with means for affixing the laminate to the skin or mucosa of the host so that the active ingredient is continuously released from the carrier layer thereto. Methods for assembling the device are also disclosed.
