ABSTRACT

Antimicrobial stewardship programmes (AMSPs) decrease antimicrobial resistance, optimize usage of antimicrobials, and enhance patient outcomes. The Anatomical Therapeutic Chemical (ATC) is the foundation of the World Health Organization (WHO) global methodology, which groups the pharmacologically active substances of antimicrobials according to their therapeutic, pharmacological, and chemical characteristics and the organ or system on which they work. Since varied unit doses of daily administration of antimicrobials are prescribed, it is best to utilize a standard approach to measure antimicrobial intake. The Defined Daily Dose (DDD) is awarded to active ingredients with an active ingredient code currently in effect. It is the anticipated average daily maintenance dose of an antimicrobial drug or substances used for their primary indication in adults. The ATC/DDD approach was created to enhance patient care by tracking antimicrobial usage and conducting research. Healthcare facilities would benefit immensely from establishing an antimicrobial stewardship programme, and more research is required to determine the baseline of antimicrobial consumption in the country.
