AIMS AND OBJECTIVE: We aimed to evaluate the prescribing pattern of antibiotics and their utilization in the adult population in atertiary care hospital. RESULTS: A total 200 patient cases were collected. Out of which 104 were male, where as 96 were female patients A total of 472 antibiotics were prescribed to the patients. Out of which there are 204 cephalosporins; 98? – lactam antibiotics (Sulbactam, tazobactam, clavulanicacid); 20 carbapenems ; 32 fluoroquinolones; 32 macrolides; 26 penicillin’s; 20 carbapenems; 16 aminoglycosides ; 14 tetracyclines; 12 antitubercular antibiotics; 8 metronidazole; 6 lincosamide antibiotics; 2 glycopeptides and 2 urinary antiseptics. Various formulations of antibiotics were given to the patients which included injections – 286; tablets – 174; capsules – 10 and drops – 2. Antibiotics that are given without combination were about 264, where as 100 antibiotics were given in double combination and 2 in more than triple combination. CONCLUSION: The study concluded that a total of 472 antibiotics were prescribed to the patients in which, class of cephalosporins was most commonly prescribed (i.e.,204) because of its high - efficacy, broad – spectrum antibacterial activity, and fewer adverse effects when compared to other antibiotics.AIMS AND OBJECTIVE: We aimed to evaluate the prescribing pattern of antibiotics and their utilization in the adult population in atertiary care hospital.
