Abstract

The invention relates to a compound preparation of an external use pharmaceutical composition for treating swelling and pain, which is a gel binder for treating swelling, and also provides its preparation method. The gel binder is prepared by 20-50% of swelling and pain medicine of the external use pharmaceutical composition for treating swelling and pain as well as proper pharmaceutical excipients. The gel binder for treating swelling is composed of a back lining layer, an ointment-containing body and a cover lining layer. The ointment-containing body, namely the kernel part, is prepared from the swelling and pain medicine, a basic polymer, a cross-linking agent, an organic acid, an excipient, a humectant, an adhesive and the like in certain ratio. The gel binder has the advantages of fast effect, good moisture preservation, high permeability and comfortable use. The product has merits of convenient usage, small irritation on skin and high compliance of patients.
