Abstract
The invention relates to an adhesive and binder for dermal or transdermal therapy systems, that includes (a) 85-99.9 weight % of (meth)acrylate copolymer of structural and functional monomers, where the functional monomers have tertiary or quaternary amino groups, (b) 0.1-15 weight % of an organic dicarboxylic or tricarboxylic acid, and (c) 40-70 weight %, relative to the total of (a) and (b), of a plasticizer.
Claims12
An adhesive and binder system for dermal or transdermal therapy, comprising:
- (a) 85-99.9 weight %, based on the total weight of (a) and (b), of a (meth)acrylate copolymer of structural and functional monomers, where the functional monomers have tertiary or quaternary amino groups,
- (b) 0.1-15 weight %, based on the total weight of (a) and (b), or an organic dicarboxylic or tricarboxylic acid,
- (c) 40-70 weight %, relative to the total weight of (a) and (b) of a plasticizer of molecular weight between 100 and 20,000 containing one or more hydrophilic groups, and
- (d) a therapeutically effective amount of pharmaceutically active substance.
