BACKGROUNDThe invention of antimicrobials emerged as a transformational turning point in the reduction of the burden of communicable disease in the 20 th century. Antimicrobials are among the most widely prescribed therapeutic agents across the world. The use of antibiotics among children is different from adults due to a number of reasons like a lack of data on pharmacokinetics, pharmacodynamics, efficacy and safety of drugs, different physiological spectrum among different age groups-preterm neonates, full-term neonates, infants and toddlers, older children and adolescents, paediatrics populations being vulnerable to the majority of the illnesses and the adverse effect of irrational use of antimicrobials being more serious among children than adults. However, antibiotic use is not explored much in a paediatric population. Existing reports of population-based antibiotic use in children are relatively few, so the present study was carried out in Berhampur city with the objectives of finding out the pattern of oral antibiotic use in children in the outpatient setting of a tertiary care hospital.
