The assortment analysis of chlorhexidine-containing medicines and procurement data of state and municipal organizations

Abstract

Chlorhexidine is an effective cationic antiseptic and disinfectant that has been used in medical practice for decades. It is generally recommended to use different concentrations of aqueous or alcoholic solutions of chlorhexidine for different therapeutic purposes. Objective. To determine the proportions of different chlorhexidine concentrations in medicines purchased by state and municipal organizations and to identify possible issue of chlorhexidine formulations utilization in the suboptimal or insufficient concentrations. Results. The vast majority of the chlorhexidine-containing medicines found in the State Register of Medicines of Ukraine are 0.05% solutions for external use, 0.05% gels for dental and urological use and vaginal suppositories (pessaries) with 16 mg of chlorhexidine in one dose. While the most common representatives of chlorhexidine-containing medicines abroad are solutions with a concentration of 4% and 2%, as well as mouthwashes with a concentration of 0.12%. The highest share - 96% - among the procurements of chlorhexidine-containing medicines by state and municipal organizations is 0.05% aqueous solution for external use. Instructions for medical use of 0.05% aqueous chlorhexidine solution for external use contain indications that are not supported by international documents: WHO Model List of Essential Medicines and British National Formulary. Conclusions. The obtained results suggest probable cases of irrational use of chlorhexidine medicines in medical practice in Ukraine. The consequences of such cases are not limited to the failure to achieve therapeutic goals or to the development of nosocomial infection, but includes also the selection of chlorhexidine-resistant strains of microorganisms.
