A method for producing a gel patch comprising an adhesive mass layer on a backing fabric, comprising a step of applying a composition comprising a physiologically active substance, a water-soluble polymer, glycerin, and water to the backing fabric to form the adhesive mass layer, wherein a loss tangent of the composition in dynamic viscoelasticity measurement at 1 Hz at a time of application to the backing fabric is 0.75 to 1.

Gel patch

Medical patch

The invention provides a gel patch comprising a support and an adhesive layer on the support, wherein the adhesive layer comprises 1.5 to 2.5 mass % of ketoprofen, 1.5 to 2.5 mass % of 4-tert-butyl-4'-methoxydibenzoylmethane and 12 to 18 mass % of propylene glycol, based on the total mass of the adhesive layer.

Ketoprofen-containing poultice

Percutaneous sorbefacients comprising hexylene glycol and 1-menthol, more particularly, percutaneous sorbefacients for female hormones or derivatives thereof; and preparations for percutaneous absorption which comprise a styrene/isoprene/styrene block copolymer and/or polyisobutylene, a softener and a tackifier as the base components, hormones, in particular, follicle hormone and/or luteal hormone as the drug component and hexylene glycol and 1-menthol as a sorbefacient.

Sorbefacients and preparations for percutaneous absorption containing the same

A device for perutaneous treatment by a serotonin receptor antagonist, comprising at least three layers including A) a drug-impermeable backing layer, B) a drug storage layer provided between the packing layer and a drug release layer and containing serotonin receptor antagonist, and C) a drug release layer constituted of a pressure-sensitive adhesive layer capable of controlling the release of a drug.
