1. A device for transdermally delivering a PTH-based agent to a patient, comprising:
- a microprojection member having a plurality of microprojections that are adapted for pulsatile delivery of a PTH based agent and to pierce the stratum corneum of the patient; and
a biocompatible coating disposed on said microprojection member, said coating being formed from a coating formulation comprising at least one PTH-based agent, wherein said PTH based agent is hPTH(1-34) or salts thereof and is at a dose of 10-1000 μ
g that results in a plasma Cmax of at least 50 pg/ml after a single application, wherein said coating formulation includes a biocompatible carrier selected from the group consisting of bioengineered human albumin, polyglutamic acid, polyaspartic acid, polyhistidine, pentosan polysulfate, polyamino acids, sucrose, trehalose, melezitose, raffinose, stachyose and mannitol, and wherein said biocompatible carrier is in the range of 2-70 wt. % of said coating formulation.

Abstract
An apparatus and method for transdermally delivering a biologically active agent 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.
