Method for the manufacture of drug permeable materials.

摘要

In the present invention, a mixture of a curable silicone rubber and a hydrous polyvinyl alcohol (hereafter "hydrous PVA"), is subjected to a treatment which cures the silicone rubber and causes low temperature (ie, below -5 DEG C) gelation of the hydrous PVA. The resultant permeable materials are used to manufacture drug delivery systems, which systems may be of the transdermal drug delivery type or of a type which is implanted either subcutaneously or in a body cavity.
