An in-line adhesive, useful in skin delivery devices, comprises a blend of high molecular weight and low molecular weight polyisobutylenes, in a GDP PME: PIB PMF ratio in the range of about 5-40. for 95-60, said adhesive being substantially free of plasticizers and tackifiers. The adhesive is particularly useful as a component of a skin delivery device for releasing oily and nonpolar agents such as nicotine, benztropine, secoverine, dexsecoverine and arecoline. |
