Chlorhexidine Gluconate is a broad-spectrum antimicrobial active pharmaceutical ingredient (API) derived from chlorhexidine. It is primarily used as a potent antiseptic and disinfectant, effective against a wide range of Gram-positive and Gram-negative bacteria, fungi, and certain viruses. Its mechanism involves disrupting microbial cell membranes. The API is a key component in medical and healthcare products, including surgical scrubs, preoperative skin preparations, mouthwashes for gingivitis, wound cleansers, and catheter site care solutions. It provides persistent antimicrobial activity due to its substantivity, binding to skin and mucous membranes. Its efficacy and safety profile make it a cornerstone in infection prevention protocols.
