摘要:
Composition of matter for application to a body surface or membrane to administer fluoxetine by permeation through the body surface or membrane, the composition comprising fluoxetine to be administered, at a therapeutically effective rate, alone or in combination with a permeation enhancer or mixture. A preferred embodiment is directed to the transdermal administration of fluoxetine at reduced skin irritation levels wherein fluoxetine, preferably provided as fluoxetine acetate, is coadministered with a corticosteroid such as hydrocortisone. Also disclosed are drug delivery devices containing the fluoxetine or fluoxetine and enhancer composition and methods for the transdermal administration of the fluoxetine and fluoxetine/enhancer composition.
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.
摘要:
An apparatus for transdermally delivering a nicotine-based agent to a tobacco or nicotine user comprising a microprojection member having a plurality of microprojections that are adapted to pierce the stratum corneum of the tobacco user, the microprojection member having a biocompatible coating disposed thereon that includes a nicotine-based agent.
摘要:
A transdermal nicotine salt delivery system to an individual. The system has a high nicotine salt loading to effect therapeutic flux rate. Acrylate polymeric drug reservoir with the high nicotine salt dissolved therein provides desirable adhesive characteristics and effective transdermal therapeutic properties.
摘要:
A transdermal electrotransport drug delivery device having an anode, a cathode and a source of electrical power electrically connected to the anode and the cathode. At least one of the anode and the cathode includes an electrode and a reservoir comprised of a housing composed of a polymeric material and an aqueous medium in contact with the housing. The aqueous medium includes (i) a drug or an electrolyte salt or a mixture thereof, (ii) propylene glycol, and (iii) an antimicrobial agent in an amount sufficient to inhibit microbial growth in the aqueous medium. The propylene glycol prevents the antimicrobial agent from being adsorbed by other materials used in the construction of the delivery device. A process for preparing a transdermal electrotransport drug delivery device is also provided.
摘要:
Buffered drug formulations for transdermal electrotransport delivery are disclosed. The formulations utilize a dipeptide as a buffer and allow for more efficient electrotransport delivery of drugs, e.g., polypeptide drugs, via the transdermal route.
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:
The present invention provides methods and compositions for stabilizing dried nucleic acids with carbohydrates such as non-reducing sugars, polysaccharides, and reducing sugars. Preferably, the stabilized nucleic acids are coated on a microprojection member for transdermal delivery. The invention further provides compositions and methods that involve the use of DNase inhibitors to stabilize dried nucleic acids delivered directly into bodily tissues.
摘要:
An electrotransport drug-containing composition is provided. The composition includes a drug to be delivered through a body surface (eg, skin) of a patient, and a permeation enhancer which is solid or semisolid at temperatures typically encountered during storage of pharmaceuticals (eg, temperatures up to at least about 25.degree. C.). The composition of the invention may be applied from a device 10 suitable for electrotransport delivery. A method for increasing electrotransport agent delivery rate and reducing body surface resistance relies on applying the composition of the invention to the body surface, and applying an electric current through the composition and the body surface.
摘要:
The present invention is directed to the transdermal administration of methyl nicotinate and an irritating or sensitizing drug. The invention includes a transdermal drug delivery device comprising a matrix adapted to be placed in irritating/sensitizing drug- and methyl nicotinate-transmitting relation with the skin site. The matrix contains sufficient amounts of irritating/sensitizing drug and of methyl nicotinate, in combination, to continuously administer to the skin for a predetermined period of time the drug to provide an effective therapeutic result. The invention is also directed to a method for either 1) preventing or reducing the irritation caused by an irritating drug or 2) preventing or reducing sensitization from occurring, as well as reducing or eliminating pain and discomfort occurring during the elicitation phase after sensitization has already been induced.
