Prescribed daily doses, Defined daily doses, ATC classification, and Drug evaluation. ,

Objectives: Our primary objective is to assess the prescribed daily doses of various drugs using the WHO ATC/DDD coding methodology. Methodology: It was a prospective observational study conducted in various departments of Sunshine Hospitals for a period of 6 months. A total of 300 prescriptions were included in the study and were followed for the drug use evaluation. This study included both male and female in-patients of age above 18 years. Results: In our study, we have observed that 50.16% of drugs have ATC/DDD values. The ratio of PDD=DDD, PDDDDD was found to be 24:81:46 respectively. Among the oral drugs acting on gastro intestinal system, proton pump inhibitors have found to be utilized the highest followed by antacids. Anti-spasmodic drugs are the drugs least utilized. Among the parenteral drugs acting on gastro intestinal system, anti-emetics have found to be utilized the highest followed by proton pump inhibitors. Among the drugs (oral) acting on cardiovascular system, HMG-CoA reductase inhibitors are found to be utilized highest followed by ARB’s. Potassium channel openers are least utilized. Conclusion: We conclude that PDD is less than DDD for majority of the drugs. DDD gives a rough estimate of drug use not the exact picture. All the drugs prescribed were in safe doses.
