Abstract

A solid drug solution perforator containing drug particles and/or drug-adsorbed or loaded particles with an associated drug reservoir (SSPP system) are provided for delivering therapeutic, prophylactic and/or cosmetic compounds, diagnostics, and for nutrient delivery and drug targeting. For drug delivery, the SSPP system includes an active drug ingredient in particulate form or drug adsorbed on the particle surface in a matrix material that dissolves upon contact with a patient's body. In a preferred method of transdermal drug delivery, an SSPP system containing a drug-adsorbed microparticle penetrates into the epidermis or dermis, and the drug is released from the (dissolving) SSPP system perforator and desorbed from the particles. An additional drug is optionally delivered from a patch reservoir through skin pores created by insertion of the perforator Formulation and fabrication procedures for the SSPP and associated reservoir are also provided. An SSPP system can be fabricated with variety of shapes and dimensions.
