摘要:
A method of making a pressure sensitive matrix patch for transdermal delivery of a drug is disclosed. The method includes the steps of dissolving a hydrophilic salt form of the drug in the water phase of an aqueous dispersion of a hydrophobic pressure sensitive adhesive, casting the resulting mixture as a thin film, and evaporating the water. The physical stability of the drug in the film is excellent, and crystallization of the drug is inhibited. A method of increasing the transdermal flux of an acidic drug is also disclosed.
摘要:
A method of transdermally or transmucosally delivering a hydrophilic salt form of a drug with a water-based pressure sensitive hydrophobic adhesive matrix patch optionally containing a permeation enhancer is disclosed. A matrix patch comprising a water-based pressure sensitive hydrophobic adhesive, a hydrophilic salt form of a drug, and optionally a permeation enhancer for transdermal or transmucosal delivery of the hydrophilic salt form of the drug is also disclosed.
摘要:
Pharmaceutical compositions with synchronized solubilizer release as well as various methods associated therewith, are disclosed and described. More specifically, the aqueous solubility of a drug is enhanced by synchronized release of a solubilizer.
摘要:
A transdermal drug delivery system which enhances the delivery of the drug comprises a composition containing, as an enhancer, one or more C.sub.6 to C.sub.22 fatty acid esters of glycolic acid and its salts. These compositions are made up of a safe and effective amount of an active pharmaceutical permeant contained in a penetration-enhancing vehicle comprising, 0.25 to 50% w. of the fatty acid glycolic acid ester enhancer in a suitable carrier vehicle. These fatty acid glycolic acid ester enhancers may be used in various carrier vehicles to enhance the transdermal delivery of active permeants in either free form or used in an occlusive device, particularly in a transdermal patch in matrix or reservoir form. When used in matrix patch form, the fatty acid glycolic acid ester enhancers and permeants are incorporated into a biocompatible adhesive. When used in a reservoir type patch, the permeant and fatty acid glycolic acid ester enhancers are incorporated into a carrier fluid of controlled viscosity such as a gel or ointment preferably containing a lower alkanol and water. In free form, the enhancer and permeant may be incorporated into an ointment, lotion, cream, or similar formulation.
摘要:
Methods and compositions for delivering a meloxicam compound are disclosed and described. In one aspect, a method may include perorally administering to a subject a therapeutically effective amount of a meloxicam compound that provides a meloxicam plasma concentration within 1 hour which is at least about 40% of the maximum plasma concentration attained by the formulation. In another aspect, a composition may include a therapeutically effective amount of a meloxicam compound in a pharmaceutically acceptable carrier including at least one of an alkalizer or a solubilizer, with the meloxicam compound having a solubility in the carrier that is greater than about 1.0 mg/gm.

摘要:
A transdermal drug delivery system which enhances the delivery of the drug comprises a composition containing, as an enhancer, one or more C.sub.6 to C.sub.22 fatty acid esters of a lactic acid salt. These compositions are made up of a safe and effective amount of an active pharmaceutical permeant contained in a penetration-enhancing vehicle comprising, 0.25 to 50% w. of the fatty acid ester of a lactic acid salt enhancer in a suitable pressure sensitive adhesive carrier vehicle formed from and aqueous emulsion based pressure sensitive adhesive.
