The present invention provides a hemostatic porous composite sponge comprising: i) a matrix of a biomaterial; and ii) one hydrophilic polymeric component comprising reactive groups wherein i) and ii) are associated with each other so that the reactivity of the polymeric component is retained, wherein associated means that said polymeric component is coated onto a surface of said matrix of a biomaterial, or said matrix is impregnated with said polymeric material, or both.

Organosilicon quaternary ammonium compounds, their formulations, including powdered and solid formulations, and methods of use to treat infections in humans and animals.

The present disclosure provides a magnetic dressing and a preparation method and use thereof, belonging to the technical field of pharmaceutical preparations. The magnetic dressing includes a magnetic layer, a drug-loading layer, and a protective layer that are stacked in sequence, where the magnetic layer includes polyvinyl alcohol, gluten, and iron particles. In the present disclosure, a swallowed magnetic dressing is controlled by an external magnetic field, and the magnetic dressing is moved to a pathological position by changing a direction of the external magnetic field; after the external magnetic field is removed, the magnetic dressing changes from a ring to a sheet, thereby completing attachment of an entire lesion surface to complete treatment by autonomous drug release.
