    • In a therapeutic system such as a plaster for administration of an active compound through the skin and comprising a covering layer which is essentially impermeable to the active compound, an active coupound reservoir layer and a protective layer which can be pulled off and which is essentially impermeable to the active compound, the improvement wherein the reservoir layer contains about 1-30% of active compound in an elastomer mixture comprising a diene rubber which can optionally be copolymerized with an .alpha.-olefin, mixed with from 0 up to about 70% by weight of a polyisobutylene, polybutadiene oil and/or paraffin oil, and a tackifying resin. Thereby the active compound can be released in regulated relatively large quantity over a prolonged period of time.
    • 在诸如用于通过皮肤施用活性化合物的石膏的治疗系统中,包括基本上不可渗透活性化合物的覆盖层,活性偶合储库层和可以被拉出并且基本上不渗透的保护层 对活性化合物的改进,其中储层在弹性体混合物中含有约1-30%的活性化合物,其包含二烯橡胶,其可以任选地与α-烯烃共聚,与0至约70重量% 的聚异丁烯,聚丁二烯油和/或石蜡油,以及增粘树脂。 因此,活性化合物可以在更长的时间内以相对大的量调节释放。

    • A medicinal plaster comprising a covering layer, a reservior layer for an active compound and a detachable protective layer is disclosed. The covering is a substantially impermeable material comprising a textile sheet-like structure which is longitudinally and transversely elastic and is impregnated or coated with a polymer. Disposed on such a covering layer is a reservior layer comprising 1 to 30% by weight of active compound is an elastomeric mixture comprising a polyisobutylene polymer, a carrier such as a polybutadiene oil or liquid paraffin and a resin such as a polybutadiene oil or liquid paraffin and a resin such as a adhesion-conferring resin. Methods for the formation of such medicinal plaster and the use of such medicinal plaster, especially to apply large dosages of antiinflammatory materials are disclosed.
