    摘要： A method of making a hydrogel having antimicrobial properties. The hydrogel includes a hydrogel-forming polymer and an anti-microbial agent. The method includes mixing a hydrogel-forming polymer, such as a hydrophilic polymer, with water and cross-linking the polymer and water using an energy source. The method does not require any chemical additive to affect the cross-linking. The anti-microbial agent may be mixed with the hydrogel-forming polymer and water prior to cross-linking. Alternatively, the anti-microbial agent may be applied to a substrate onto which the hydrogel is placed such that the anti-microbial agent or the properties of the agent, or both, migrate into the hydrogel. The substrate may be a liner onto which the hydrogel is placed, a scrim located on or in the hydrogel, or other appropriate device.

    摘要： Crosslinked hydrogel-based transdermal pharmaceutical formulations. The hydrogel transdermal formulations. Transdermal patches are useful for administering a variety of drugs to patients. The transdermal patches here employ crosslinked-hydrogels generated through irradiation, thus eliminating any residual effects associated with chemical- or UV-based crosslinking procedures. The transdermal patches may be formed from a variety of high-molecular weight polymeric compounds and include substantial levels of water to improve skin tolerance by the patient. The transdermal patches may also include transcutol as a solvent for the drug, which has been found to increase the effectiveness of drug delivery. The present disclosure also provides for methods of loading a drug into a transdermal formulation after the crosslinking of the hydrogel, thus improving stability and bioavailability through avoiding exposure of the drug to the radiation used in the crosslinking procedure. The transdermal patches here are particularly effective in delivering lidocaine to patients in need thereof.
