Measurement of Antipyretic Activity of Ibuprofen and Paracetamol in Children

The antipyretic activity of ibuprofen (Brufen) and paracetamol (Crocin) was compared in 22 children with pyrexia who received either ibuprofen or paracetamol in syrup form. Both axillary and rectal temperatures were recorded prior to drug administration and 1/2, 1, 2, 3, 4, 5, 6, 8, and 12 hours after dosing. Analysis of the results in terms of rate of temperature decrease and degree and duration of decrease in temperature indicated that both drugs produced significant reduction in temperature and in the rate of temperature decrease. The maximum effect of the two drugs was similar. However, ibuprofen was more effective than paracetamol at 6 and 8 hours after administration, and its duration of action was longer. The associated antipyretic and antiinflammatory features of ibuprofen could provide an advantage in the control of exudative forms of upper respiratory tract infections.
