Chlorhexidine is a bisbiguanide antiseptic and disinfectant widely used for skin disinfection and oral hygiene, often formulated in combination with other antimicrobial agents. It is commonly used to prevent infections in wounds, preoperative skin preparation, and in dental care for plaque control. Chlorhexidine is approved for use in many countries and remains in contemporary use.
Pharmacokinetics
No published pharmacokinetic models for chlorhexidine in combination (ATC D08AC52) exist. Below are estimated PK parameters for topical administration in adults based on physicochemical properties and limited absorption.
