The full form of ATC in pharma is Anatomical Therapeutic Chemical.
The Anatomical Therapeutic Chemical (ATC) classification system is a vital tool in the pharmaceutical industry. It's used to classify drugs according to the organ or system on which they act, along with their therapeutic, pharmacological, and chemical properties. This hierarchical system allows for standardized drug utilization studies, making it easier to compare drug consumption data both nationally and internationally.
Key Aspects of the ATC Classification System:
-
Hierarchical Structure: The ATC system uses a five-level classification, providing increasingly specific categorization:
- 1st Level: Anatomical main group (e.g., A - Alimentary tract and metabolism)
- 2nd Level: Therapeutic subgroup (e.g., A02 - Drugs for acid-related disorders)
- 3rd Level: Pharmacological subgroup (e.g., A02B - Drugs for peptic ulcer and gastro-oesophageal reflux disease (GORD))
- 4th Level: Chemical subgroup (e.g., A02BA - H2-receptor antagonists)
- 5th Level: Chemical substance (e.g., A02BA02 - Ranitidine)
-
Applications:
- Drug Utilization Research: Enables consistent monitoring and comparison of drug use patterns.
- Epidemiology: Supports studies related to drug safety and efficacy.
- Prescribing Guidelines: Facilitates the development and implementation of evidence-based prescribing.
- Reimbursement Policies: Informs decisions related to drug coverage and pricing.
-
Maintenance and Updates: The ATC system is continuously updated to reflect new drugs and changes in therapeutic knowledge. The World Health Organization (WHO) collaborates with the Collaborating Centre for Drug Statistics Methodology to maintain and develop the ATC/DDD system.
In summary, the Anatomical Therapeutic Chemical (ATC) classification system provides a standardized and comprehensive framework for classifying drugs, which is essential for various aspects of pharmaceutical research, regulation, and healthcare management.
