Device for transdermal administration of drugs including acrylic polymers

A transdermal drug delivery system comprising a blend of:

• (a) a polymer composition of at least one acrylic-based polymer which acrylic-based polymer is polymerized with monomers that include:
• (i) a soft acrylic monomer having a glass transition temperature (Tg) from about −70° C. to about −10° C. in an amount of from 50% to 70% by weight of the acrylic-based polymer;
• and (ii) a hard acrylic monomer having a glass transition temperature (Tg) from about −5° C. to about 120° C. in an amount of from 30% to 50% by weight of the acrylic-based polymer;
• and
• (b) 0.1% to about 50% by weight of the transdermal drug delivery system of one or more drugs incorporated into the polymer composition.

A transdermal drug delivery system comprising a blend of:

• (a) a polymer composition of at least one acrylic-based polymer which acrylic-based polymer is polymerized with monomers that include:
• (i) a soft acrylic monomer selected from the group consisting of 2-ethyl hexyl acrylate, isobutyl acrylate, dodecyl methacrylate, 2-ethoxyethyl acrylate, isopropyl acrylate, and 2-methoxyethyl acrylate in an amount of from about 20 to about 70% by weight of the acrylic-based polymer;
• and (ii) a hard acrylic monomer selected from the group consisting of N-butyl acrylate, acrylic acid, ethyl methacrylate, hexyl methacrylate, and methyl acrylate in an amount of from about 30 to about 80% by weight of the acrylic-based polymer;
• and
• (b) 0.1% to about 50% by weight of the transdermal drug delivery system of one or more drugs incorporated into the polymer composition.
