Abstract
This study aims to develop a novel hemostatic gel of hemocoagulase, a snake venom-derived serine protease enzyme, by incorporating it into the matrix of bioadhesive polymers to prevent damage due to hemorrhage. Haemocoagulase was combined with polymers Carbopol 940 and HPMC K 100, and these formulations were evaluated for physical properties, efficacy, safety and stability. Batches F3 and F6 were selected for further studies on animal models, which were found to be safe without any skin irritation effect and effective as hemostats with blood clotting times of 1.24 ± 0.007 min and 1.36 ± 0.014 min, respectively, in a rat liver incision model. From this study, it can be suggested that the combination of hemocoagulase with bioadhesive polymer can provide a novel hemostatic tool for controlling bleeding.
