摘要:
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, 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:
This invention relates to a method for inhibiting a decrease in the transdermal flux of an agent that is being transdermally delivered or sampled over a prolonged period of time wherein the delivery or sampling involves disrupting at least the stratum corneum layer of the skin to form pathways through which the agent passes. The desired result is achieved by co-delivering or co-sampling the agent with an amount of at least one anti-healing agent wherein the amount of the anti-healing agent is effective in inhibiting a decrease in the agent transdermal flux compared to when the delivery or sampling of the agent is done under substantially identical conditions except in the absence of the anti-healing agent(s).
摘要:
A transdermal drug delivery system with microprojections for disrupting a body surface to an individual. At least some of the microprojections form groups in a microprojection array. There are repeated units of such groups in the microprojection array.

A transdermal drug delivery system with microprojections for disrupting a body surface to an individual. At least some of the microprojections have a depression for increasing drug loading by a drug coating.
摘要:
A transdermal delivery system having a microprojection array with one or more voids configured to allow an adhesive backing to attach to a user's skin and, hence, improve retention of the system thereto. Radial voids can be configured to enhance compliance of the array to conform more readily to non-flat areas of the skin.
摘要:
An apparatus and method for transdermally delivering a natriuretic peptide comprising a delivery system having a microprojection member 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 natriuretic peptide is contained in a biocompatible coating that is applied to the microprojection member. In a further embodiment, the delivery system includes a natriuretic peptide-containing hydrogel formulation. In an alternative embodiment, the natriuretic peptide is contained in both the coating and the hydrogel formulation. In yet another embodiment, the natriuretic peptide is contained in a solid state formulation.
摘要:
An apparatus and method for transdermally delivering an immunologically active agent comprising a delivery system having a microprojection array that includes a plurality of microprojections that are adapted to pierce through the stratum corneum into the underlying epidermis layer, or epidermis and dermis layers, the microprojection array having a plurality of array regions, each of the array regions having a different biocompatible coating disposed thereon, wherein at least one of the array region coatings includes an immunologically active agent. In one embodiment, each coating on the array regions includes a different immunologically active agent. In another embodiment, the biocompatible coating on a first array region includes an immunologically active agent and the biocompatible coating on a second array region includes an immune response augmenting adjuvant.
摘要:
A device (12) and method are provided for percutaneous transdermal delivery of a potent pharmacologically active agent. The agent is dissolved in water to form an aqueous coating solution having an appropriate viscosity for coating extremely tiny skin piercing elements (10). The coating solution is applied to the skin piercing elements (10) using known coating techniques and then dried. The device (12) is applied to the skin of a living animal (e.g., a human), causing the microprotrusions (10) to pierce the stratum corneum and deliver a therapeutically effect dose of the agent to the animal.
摘要:
An apparatus and method for transdermally delivering desmopressin 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 desmopressin is contained in a biocompatible coating that is applied to the microprojection member.
