| titleOfInvention | Hydrophilic pressure sensitive adhesive for topical administration of hydrophobic drugs |
| abstract | New hydrogel formulations useful for forming adhesive reservoirs for topical or transdermal administration. These formulations comprise as polymer base a polymer or a crosslinked copolymer of 2-acrylamido-2-methylpropanesulfonic acid or a salt thereof. The gels are prepared from polymerizable compositions comprising: 20% - 50% of a monofunctional monomer component, at least 75% of said component comprising 2-acrylamido-2-methylpropane sulfonic acid or a salt thereof, the remainder being selected from the group consisting of acrylic acid, water-soluble acrylic functional monomers and vinyl pyrrolidone; 30% - 50% of a glycol selected from the group consisting of compounds of the formula: HO- (C2H4O) nH, HO- (C3H6O) mH and mixtures thereof, formula in which n is between 4 and about 16 and m is 1-4; between about 0.02% and about 0.20% of a crosslinking monomer; an amount of a free radical polymerization initiator for initiating polymerization of said monofunctional monomers and said crosslinking monomer; and a therapeutically effective amount of a drug which can be administered locally or transdermally, at least about 60% of said drug being dissolved in the composition. |
