摘要:
A transdermal delivery system for the administering of ethinyl estradiol and levonorgestrel, in combination, utilizing a polymer matrix having the drug formulation along with a permeation enhancer dispersed throughout.
摘要:
A method for preventing the formation of crystalline hydrates in a dispersion of a hydratable liquid in a nonaqueous matrix is disclosed. The method is particularly useful in the manufacture of laminated items formed from such dispersions and comprises forming individual subunits from such dispersions, heating the subunits, preferably after they have been packed in sealed containers, to a temperature high enough to melt the crystalline hydrate, maintaining said subunits at such temperature for a time sufficient to melt all the crystalline hydrate present and to prevent the occurrence of crystals for an extended period of time after cooling and cooling subunits to ambient conditions. The use of the method in the manufacture of transdermal delivery devices for the delivery of scopolamine base is described.
摘要:
A transdermal therapeutic system is provided which is adapted for delivery of a biologically active agent over an extended time period said system comprising a matrix containing an agent disposed therein, the intended body distal surface of said matric having fibrous reinforcing means embedded therein, said matrix being capable of firm adhesion to the skin but with a peel strength sufficiently low for removal without discomfort. The reinforcing means comprises a stretchable fabric formed of either randomly or orientated bonded fibres to form an isotrophic web substantially equally deformable in all directions, or anisotrophic web formed of a multiplicity of continuous generally parallel fibres having randomly orientated second fibres bonded transversly thereto so as to be deformable primarily in a direction perpendicular to the continuous fibres.
摘要:
A device for the transdermal administration of fluoxetine (10) at a therapeutically effective rate comprises: (a) a reservoir (12) containing a composition comprising an amount of a pharmaceutically acceptable salt of fluoxetine; (b) a backing (14) behind the body contacting-distal surface of the reservoir; and (c) means (16) for maintaining the reservoir in fluoxetine transmitting relation with a body surface or membrane.

摘要:
Composition of matter for application to a body surface or membrane to administer pergolide by permeation through the body surface or membrane, the composition comprising pergolide to be administered, at a therapeutically effective rate, alone or in combination with a permeation enhancer or mixture. Also disclosed are drug delivery devices containing the pergolide or pergolide and enhancer composition and methods for the transdermal administration of the pergolide and pergolide/enhancer composition.
