摘要:
An apparatus and method for transdermally delivering a biologically active agent to prevent or treat osteopenia, comprising a delivery system having a microprojection member (or system) that includes a plurality of microprojections (or array thereof) that are adapted to pierce through the stratum corneum into the underlying epidermis layer, or epidermis and dermis layers. In one embodiment, the PTH-based agent is contained in a biocompatible coating that is applied to the microprojection member.

In one embodiment, an Epoetin-based agent is contained in a biocompatible coating that is applied to the microprojection member. In a further embodiment, the delivery system includes a gel pack having an Epoetin-based agent-containing hydrogel formulation that is disposed on the microprojection member after application to the skin of a patient. In an alternative embodiment, the Epoetin-based agent is contained in both the coating and the hydrogel formulation.

摘要:
Compositions of and methods for formulating and delivering biologically active agent formulations having enhanced physical stability, and wherein deterioration from the presence of oxygen and/or water is minimized and/or controlled, to yield a stable formulation. The compositions of and methods for formulating and delivering biologically active agents of the present invention further facilitate their incorporation into a biocompatible coating which can be employed to coat a stratum-corneum piercing microprojection, or a plurality of stratum-corneum piercing microprojections of a delivery device, for delivery of the biocompatible coating through the skin of a subject, thus providing an effective means of delivering the biologically active agents.
摘要:
A formulation for coating a transdermal delivery device having a plurality of stratum corneum-piercing microprojections, the formulation including a biologically active agent and at least one viscosity-enhancing counterion. Preferably, the formulation has a viscosity in the range of about 20-200 cp.
摘要:
The invention provides for a formulation for coating one or more microprojections using a non-volatile counterion to improve solubility of a biologically active agent. The invention also includes formulations having a volatile counterion to reduce the solubility of a portion of the biologically active agent.
