Out of 433 drugs which were prescribed to 130 patients, 316 were antibiotics. The average numbers of antibacterial agents which were prescribed per patients per course was found to be 3.88 and average cost per prescription per day was Rs.210.50 and the average antibiotic cost per encounter was Rs.168.50. Conclusion: Our study demonstrated that most of the prescription were found to be rational according to the use of AMAs which helps in reducing adverse events and health care cost.
