ABSTRACTObjective: To evaluate the effects of low daily aspirin doses on uric acid (UA) level and renal functions in healthy adults.Methods: Healthy adults were randomized to receive 100 mg (n= 33), or 300 mg (n = 31) aspirin daily for one month. Laboratory tests included measurement of blood urea nitrogen (BUN), serum creatinine, and uric acid (UA) levels. Urine creatinine, urea and uric acid excretion were measured in a 24 h collection of urine, 24 hours urine uric acid, creatinine clearance (Ccr), were measured at baseline and then after 4 weeks of therapy.Results: After 4 weeks of therapy, 100 and 300 mg/d dosage, aspirin caused a 7% and 12% decrease in the rate of UA excretion respectively (P< 0.05). Patients at the dosage 300 mg/d but not the 100mg/day had an increase in serum levels of uric acid (UA), creatinine and urea with a significant decrease in 24 hour creatinine clearance and urinary urea excretion (P<0.05) when compared with the baseline.Conclusion: Because of the effects of 300 mg dose aspirin, in the lowering of kidney function and the potential of aspirin to cause dose-dependent impairment of renal function, patients taking low-dose aspirin therapy should be monitored for the development of impaired renal function.Keywords: Low dose aspirin, renal function, healthy adult.
