A method of coating a microneedle array by applying a coating fluid using a flexible film in a brush-like manner. A method of coating a microneedle array comprising: providing a microneedle array having a substrate and a plurality of microneedles; providing a flexible film; providing a coating solution comprising a carrier fluid and a coating material; applying the coating solution onto a first major surface of the flexible film; performing a transfer step of bringing the first major surface of the flexible film into contact with the microneedles and removing the flexible film from contact with the microneedles; and allowing the carrier fluid to evaporate. Also, a method of coating a microneedle array by applying a coating solution onto a first major surface of a coating substrate to form a layer of applied coating solution having a thickness equal to or less than the height of at least one of the microneedles and performing a transfer step of bringing the first major surface of the coating substrate into contact with the microneedles and removing the coating substrate from contact with the microneedles, thereby transferring at least a portion of the coating solution to the microneedle array.

Method of contact coating a microneedle array

A method of coating a microneedle array comprising: providing a microneedle array having a substrate and at least one needle; providing a removable masking layer on the microneedle array such that the substrate is at least partially covered by the masking layer and the at least one needle remains at least partially exposed; and applying a coating material to at least a portion of the exposed portion of the microneedle array.

Masking method for coating a microneedle array

A transdermal delivery device including at least one pressure sensitive adhesive layer having a first major surface and a second major surface, wherein at least one of the first and second major surfaces is a structured surface; a cap layer in contact with the structured surface of an adhesive layer; and, at least one medicinal ingredient between the adhesive layer and the cap layer.

Transdermal delivery devices

A preformed object for delivering an active agent for a subject, the preformed object including crosslinked protein, and methods of making and using.

Delivery systems using preformed biodegradable polymer compositions and methods

Transdermal drug delivery compositions comprising pressure sensitive adhesive microspheres that contain a softening agent and/or a drug. Typically the microspheres contain at least 10 wt-% of a softening agent. The drug and/or softening agent can be incorporated into the microspheres during or after their formation.
