ABSTRACT
Background: Drug utilization study is an important tool to study the clinical use of drugs and its impact on healthcare system. DUS in patients with HTN and DM is essential to observe the changing prescribing attitude of physicians with the aim to promote rational use of drugs and to minimize the adverse drug reactions.Methods: A cross sectional observational study was conducted on randomly selected patients attending medicine outpatient department in a tertiary care hospital. Drug prescription sheets of 600 patients were studied for 18 months from January 2016 to June 2017 and the prescribing pattern was analysed using the World Health Organization basic drug indicators.Results: Total 2029 drugs were prescribed to 600 patients that belonged to various classes. The average number of drugs prescribed per encounter was 3.4. Majority (61.5%) drugs were prescribed using generic names. Percentage encounters with the antibiotics and injections were 6.3 and 11.5 per cent respectively. 38% drugs were prescribed from the 20th edition of WHO Model List of Essential Medicines. PDD in the current study was found to be significantly less than WHO DDD in all drugs. All of the prescriptions in the present study conformed to WHO guidelines and majority of them with JNC VIII guidelines.Conclusions: The findings of this study are comparable to those of other studies. However, there is a scope of improvement in areas such as overdosing, prescribing more by generic names instead of brand names and from WHO Model List of Essential Medicines.
ABSTRACT
Introduction: The geriatric population assumes great significance in terms of both preventive and curative health care services utilized. The patho-physio-psychological changes associated with ageing make their problems unique. In the geriatric population, hypertension accounts for a huge proportion of cardiovascular and all cause mortality and morbidity. We conducted a study to describe the patterns of antihypertensive drug use in the geriatric population, compare it to the current recommendations and conduct an analysis using the WHO-INRUD drug use indicators. Methods: A prospective cross sectional drug utilization study of 100 prescriptions of hypertensive patients (as per JNC 7) of either sex and ≥60 years was undertaken as per the WHO – DUS and the STROBE guidelines. Results: Statistically significant relation was found between BP control, and addictions and CIRSG score. The 100 prescriptions contained 344 drugs, out of which, 171 were antihypertensive drugs. Three percent of antihypertensive drugs were prescribed by generic names. Seventy nine percent of antihypertensive drugs were prescribed from the ‘hospital drug schedule’. Amlodipine, Hydrochlorothiazide, Losartan and Telmisartan were prescribed to 79%, 24%, 11%, 11% respectively. The combination of ARB (Angiotensin Receptor Blocker) + Diuretic was prescribed to 36% and that of ARB + CCB (Calcium Channel Blocker) was prescribed to 21%. The PDD/DDD ratios of Carvedilol, Losartan, Furosemide and Telmisartan were 0.7, 0.8,1 and1.2, respectively. Conclusion: Creating awareness regarding the role of addiction in BP control and advocating lifestyle changes is paramount in HTN management. Overall, the principles of rational prescribing were followed. The prescription pattern observed was as per current recommendations.
