Abstract:
Antipyrine elimination was studied in 11 type I and 10 type II diabetic patients and 2 age-matched control groups. After oral administration of antipyrine (15 mg/kg), salivary concentration of the drug was measured at various time intervals by high performance liquid chromatography method. In type I diabetics the clearance rate (CL) and apparent volume of distribution (V) of the drug were significantly higher when compared to corresponding controls. The elimination half-life (t 1/2) remained unaltered. In type II diabetics, the t 1/2 of the drug was increased due to increase in V. There was no significant difference in CL. It is concluded that antipyrine elimination is enhanced in type I diabetics while in type II patients it is unaltered.
