Effect of Chitosan on sustained release of chlorhexidine –an in vitro study
نویسندگان
چکیده
Introduction: The aim of the study was to evaluate the sustained release effect of 2% chlorhexidine and its combination with 2% chitosan, in vitro. Method: The sustained release effect of chlorhexidine and its combination with chitosan was determined using a UV spectrophotometer. Results: UV spectrophotometer analysis for the sustained release of chlorhexidine showed that almost 100% of chlorhexidine was released within 4 hours. However when chlorhexidine was combined with chitosan, only 59% of chlorhexidine release was observed even at 24 hours. Conclusion: The percentage drug release of chlorhexidine was almost half when used in combination with chitosan, thus indicating the sustained release property of chitosan.
