    摘要: A composition for transdermal delivery of a progestin for progestin hormone therapy is disclosed. Also disclosed is a transdermal delivery device comprising the composition. For progestin-only hormone therapy, the composition contains an anti-oxidant and does not contain an estrogen. For therapy involving a progestin and an estrogen, the composition contains the progestin, the estrogen and an additional anti-oxidant. Methods of improving the stability of progestin-containing compositions comprising oxidative agents are also disclosed. The methods comprise including one or more anti-oxidants in the compositions.

    摘要: Methods for producing poly�urethane-(meth)acrylate!-based adhesives in which an isocyanate-terminated prepolymer is reacted to convert the isocyanate terminal groups into groups capable of cross-linking with each other, excess isocyanate groups are quenched with an isocyanate group quenching compound and the resulting prepolymer is then irradiated or heated to form the polyurethane-based adhesives, and adhesives produced thereby. Alternatively, a hydroxyl-terminated prepolymer is reacted with a reagent having isocyanate and methacrylate groups to form a prepolymer which is then irradiated or heated.
