We prepared pressure-sensitive adhesive (PSA) patches based on styrene–isoprene–styrene (SIS) thermoplastic elastomer using hot-melt coating method. The liquid paraffine is added in the PSA matrices as a plasticizer to moderate the PSA properties. Three drugs, methyl salicylate, capsaicin, and diphenhydramine hydrochloride are selected as model drugs. The(More)
A novel drug-in-adhesive matrix was designed and prepared. A thermoplastic elastomer, styrene–isoprene–styrene (SIS) block copolymer, in combination with tackifying resin and plasticizer, was employed to compose the matrix. Capsaicin was selected as the model drug. The drug percutaneous absorption, adhesion properties, and skin irritation were investigated.(More)
