ABSTRACT
OBJECTIVES: To assess the polypharmacy and appropriateness of prescriptions in geriatric patients in a tertiary care hospital. METHODS: An observational study was done in geriatric patients (>60 years) of either gender. The data collected from patients included: Socio-demographic data such as age, gender, marital status, educational status, socioeconomic status, occupation, nutritional status, history of alcohol/smoking, exercise history, details of comorbid diseases, medication history, findings of clinical examination etc. In this study, polypharmacy was considered as having 5 or more medications per prescription. Medication appropriateness for each patient was analysed separately based on their medical history and clinical findings by applying medication appropriateness index, screening tool to alert to right treatment (START) and Beers criteria and STOPP criteria. RESULTS: A total of 426 patients, 216 (50.7%) were males and 210 (49.3%) were females. Polypharmacy was present in 282 prescriptions (66.2%). Highest prevalence of polypharmacy was seen in 70-79 years age group compared to the other two groups and it was statistically significant. Out of 426 patients, 36 patients were receiving drugs which were to be avoided as per Beers criteria. Among the total patients, 39 patients were overprescribed as per MAI, 56 patients were under prescribed as per START criteria and 85 out of 426 prescriptions were inappropriate in accordance with beers criteria, stop criteria, start criteria and MAI index. CONCLUSION: Around 66.19% patients were receiving polypharmacy. Significant number of patients were receiving drugs which are to be avoided as well as overprescribed and under prescribed. Inappropriate prescription was seen in a good number of patients.

OBJECTIVE: The objective was to evaluate the acute effect of melatonin on ethanol drinking in ethanol naïve rats and to determine the specificity of the effect of melatonin on ethanol intake as compared to an intake of plain tap water or sugar water. MATERIALS AND METHODS: A total of three experiments (2 weeks duration each) using different drinking solutions (ethanol, plain tap water, sugar water) was conducted in individually housed male wistar rats of 5 weeks age. Each animal had access to bottles containing drinking solutions for 2 h a day. In each experiment, on day 1, day 2, day 4, day 5, day 8, day 9, day 11, day 12 rats received drinking solutions. Each individual rat received single doses of saline, melatonin (50 mg and 100 mg/kg), and naltrexone on day 2, 5, 9, and 12, 1-h before receiving drinking solution. The order of drug administration is permuted such a way that each animal received the drugs in a different order in different experiments. RESULTS: Melatonin has significantly decreased ethanol consumption by the rats and effect is dose-dependent. Naltrexone also has caused a significant reduction in the ethanol consumption. The maximum reduction in ethanol consumption was seen with melatonin 100 mg/kg dose compared to melatonin 50 mg/kg and naltrexone. There was no statistically significant effect of melatonin on plain water and sugar solution intake. CONCLUSIONS: Melatonin decreases ethanol consumption in ethanol naïve rats. The effect of melatonin is similar to naltrexone affecting selectively ethanol consumption, but not plain water and sugar water consumption.
