Abstract
A novel active agent-eluting hemostatic agent and methods of use and manufacture thereof are presented. A polymer, such as gelatin, is used as the base for a hemostatic agent. The gelatin is crosslinked with a chemical crosslinker, such as a carbodiimide, in the presence of an active agent. The active agent may be an anesthetic or antimicrobial, such as an antibiotic. The novel process allows for the active agent to be both covalently bound to the gelatin as well as be trapped within cages in the gelatin that are formed from the crosslinking. This dual measure allows for controlled and sustained release of the active agent from the hemostatic agent to reduce surgical site infections.
