Purpose: Drug use prescribing indicators advocated by the World Health Organization (WHO) are important tools for assessing the degree of polypharmacy, use of generic medicines, and to evaluate if there is inappropriate use of antibiotics or parenteral medications besides estimating the adherence to the essential drugs list. This study aimed to assess the WHO prescribing indicators in prescriptions given at the medical outpatient department (OPD) in a private medical college hospital in South India. Materials and Methods: The study was done prospectively from patients when they presented for consultation at the medical OPD at our tertiary care center. Prescriptions were randomly chosen to be analyzed for the WHO prescribing indicators from September 2016 to April 2017. Results: A total of 700 prescriptions were analyzed and the average number of drugs per prescription was 2.955 ± 1.32. 32.57% of prescriptions had fixed drug combinations and a similar value of 36% was obtained for prescriptions containing more than one drug for the same indication. Amongst the prescribing indicators, generic prescribing was appallingly low (6.42%). In contrast, antibiotic prescribing and prescription of injections showed an appreciably rational trend with 15.42% and 8.14%, respectively. Furthermore, the prescription of the drugs enlisted in the essential drugs list was determined to be 90.67%. Discussion: The need for increase in generic prescribing and augmenting the adherence of prescriptions to the essential drugs list has been identified. This can be accomplished by multimodal approach that includes regulatory changes, conducting educational programs directed at attitudinal change among current doctors and imparting modifications in medical curriculum so as to inculcate the culture of abiding by the best prescription practices among budding doctors. Conclusion: This study has delineated the requisite for pertinent changes in current prescribing trends in a tertiary care teaching private colleges.
