ATC Classification System - INI

The ATC (Anatomical Therapeutic Chemical) Classification System is an international classification system for drugs developed and maintained by the World Health Organization (WHO). It classifies the active ingredients of drugs based on the organ or system on which they act (anatomical), as well as their therapeutic, pharmacological, and chemical properties, using a five-level hierarchical structure. It is widely used for international comparison of drug utilization statistics, epidemiological studies, and prescription analysis.
