Trypsin is a proteolytic enzyme that has been explored for its therapeutic effects in treating soft tissue injuries, including sprains. The rationale for its use is based on its ability to break down proteins, which is thought to help reduce inflammation, edema, and hematoma by promoting the removal of necrotic tissue and inflammatory exudates at the injury site. Some clinical studies, primarily from India and a few other countries, have evaluated oral or topical preparations containing trypsin, often in combination with other enzymes like bromelain and rutin, for the management of musculoskeletal injuries.

Evidence supporting trypsin's efficacy in treating sprains is moderate but mixed. Some small randomized controlled trials have shown that enzyme therapy may reduce pain and swelling more quickly than placebo or standard care, potentially leading to faster recovery. However, these studies often use multi-enzyme combinations, making it difficult to attribute the benefits solely to trypsin. Additionally, many of these trials suffer from methodological limitations such as small sample sizes, lack of rigorous blinding, or insufficient long-term outcomes.

Overall, while there is some scientific validation for the use of trypsin (usually as part of enzyme combinations) in the management of sprains, the quality and quantity of evidence are not robust. International guidelines do not routinely recommend trypsin for sprains, and further high-quality, independent research is needed to conclusively establish its efficacy and safety for this indication.
