tested as penetrationenhancers in the diffusion of various drugs through hairless mouse skin in vitro. Hexamethylenelauramide (hexahydro-1-lauroyl-1H-azepine) was selected as a broad spectrum penetrationenhancer worthy of further study. Later, the duration of the effect of various enhancers on the penetration barrier in vivo was determined by evaluating the in vitro diffusion of hydrocortisone through
A composition useful for topically administering physiologically active agents through the skin and mucous membranes of humans and animals in a transdermal device or formulation for systemic use or to the skin of humans and animals for localized use comprising an effective amount of a physiologically active agent and a non-toxic, effective penetrating amount of a compound having the structural formula ##STR1## where R is an alkyl group with 1 to 19 carbon atoms, and m is 4, 5 or 6 is disclosed.
A resin composition comprising alicyclic structure-containig polymer such as additional copolymer with monomer having norbornene structure and ethylene, hydrogenated product of ring-opening polymer with monomer having norbornene structure, and aromatic ring-hydrogenated product of copolymer with styrene and isoprene; and piperidine derivatives such as N,N'-bis(2,2,6,6-tetramethyl-4-piperidyl)-N,N'-diformyl-hexamethylenediamine and 4-(formyl amino)-2,2,6,6-tetramethyl piperidine.
