ADHESIVE HYDROGELS HAVING EXTENDED USE LIVES AND PROCESS FOR THE PREPARATION OF SAME |
摘要 |
2123487 9310163 PCTABS00022 This invention relates to a non-stringy adhesive hydrophilic gel comprising an aqueous mixture of a radiation crosslinkable water-soluble polymer, at least one humectant effective to extend the moisture retaining characteristics of the gel and which inhibits the ability of radiant energy to crosslink the water-soluble polymer, a pharmacologically active agent, and a crosslinking promoter effective to counteract the crosslinking inhibitory effect of humectant. The aqueous mixture is exposed to radiant energy effective to provide a non-stringy adhesive cohesive homogeneous hydrophilic gel that has an extended in-use lifetime. The gels can be formed into PATCHES for long term application of the pharmacologically active agent to a patient.
