Synthetic resin matrix drug storage and topical drug delivery dressing for veterinary usage

摘要

A synthetic resin matrix dressing is disclosed consisting essentially of a polymer, such as poly(2-hydroxyethylmethacrylate), referred to as PHEMA, an organic solvent, such as polyethylene glycol (PEG), and a hydrogen bonding plasticizer, such as dimethylsulfoxide (DMSO). The plasticizer regulates the set-up time of the synthetic resin so that the more plasticizer present, the shorter the set-up time. The dressing may be applied to the treatment site in veterninary use in the form of a paste for the in-situ curing or setting thereof, or the dressing may be preformed and then applied to the treatment site. A variety of drug agents may be incorporated in the synthetic resin matrix so as to result in the time released administration of the drug agent to the area of the skin covered by the dressing. A method of treatment using this dressing is also disclosed.
