摘要:
Percutaneous sorbefacients comprising hexylene glycol and l-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 l-menthol as a sorbefacient.
摘要:
Adhesive preparations which little irritate the skin, have an excellent stability over prolonged storage and a high heat stability and show favorable adhesiveness in using. Namely, adhesive preparations comprising a styrene-isoprene-styrene block copolymer, polyisobutylenes, a takcifier, a plasticizer and a drug component, characterized in that two or more polyisobutylenes having different average molecular weights are used in combination, the viscosity of the adhesive in the adhesive preparations ranges from 1,500 to 30,000 P (60 DEG C), and the adhesive force thereof ranges from 5 to 200 g/10 mm.
摘要:
This invention provides a patch with less skin stimulation, excellent in long time store stability and heat stability and having favorable tack during use. The patch comprising a styrene - isoprene - styrene block copolymer, polyisobutylene, tackifier, plasticizer and pharmaceutically effective ingredient, in which two or more kinds of polyisobutylene of different average molecular weight are used in combination and the viscosity of the adhesive of the patch is between 1500 and 30,000 poise (at 60°C) and the tack of the patch is from 5 to 200 g/10 mm.
