ABSTRACT
Context: Rational drug use has a great role of influence in health care. The fact sheet given by the World Health Organization (WHO) shows that around 50% of the drugs are prescribed, dispensed, and sold inappropriately. One of the major consequences of irrational drug use in infections is antibiotic resistance. Aim: The present study aims to assess the antibiotic-prescribing pattern by auditing the prescriptions in a teaching hospital. Settings and Design: A prospective cross-sectional study was conducted in the pharmacy of a teaching hospital to evaluate the prescriptions of the outpatient department. Materials and Methods: The prescriptions used to treat symptoms suggestive of infections were taken into consideration. A total of 1,000 prescriptions were analyzed. Data Analysis: The data was analysed using Microsoft Excel. Results: A total of 2,536 drugs were prescribed. The average number of drugs per prescription was 2.5. The percentage of encounters with antibiotics prescribed was 17.5%. The percentage of encounters prescribed with a generic name and with drugs from the essential drug list was 87.5% and 65%, respectively. There were no injections prescribed. Amoxicillin and ciprofloxacin were the most common antibiotics prescribed. The duration of the treatment was mentioned in all the prescriptions. Conclusions: Our study shows that the percentage of antibiotic usage is within the WHO standard value. The average number of drugs per prescription was slightly higher than the WHO value. Steps should be taken to improve the generic prescribing by the physicians.
ABSTRACT
Hypertension was induced in male Sprague Dawley rats with twice weekly administration of deoxycorticosterone acetate (DOCA) salt (20 mg/kg s.c) for 4 weeks. They were divided into eight groups of six animals each viz., hypertensive control, standard (prazosin 1 mg/kg), cleistanthin A 12.5, 25, 50 mg/kg and cleistanthin B 12.5, 25 mg/kg, and 50 mg/kg. One more group served as normal control. The hypertension was induced in 4 weeks, and the animals were given assigned treatment in 5(th) week. The alteration in blood pressure (BP) was recorded weekly using a rodent noninvasive blood pressure system. At the end of the experiment alpha-adrenergic receptor response of drugs like adrenaline, nor adrenaline, dopamine (doses 1 µg and 2 µg) was recorded invasively. Two-way repeated measures ANOVA followed by Bonferroni post-hoc test was used to analyze the data. The systolic BP and diastolic BP of test groups rose to a higher level after DOCA administration and fell to the normal range (P < 0.05) following the administration of cleistanthins A and B. There were no differences in the weekly heart rate among the groups. In the test group animals pretreated with prazosin and cleistanthins, adrenaline, noradrenaline and dopamine failed to raise the mean arterial pressure and the end-diastolic pressure from baseline (P > 0.05) cleistanthins A and B exert a significant antihypertensive effect through alpha-adrenergic receptor blockade similar to prazosin.
