1. Salivary elimination of paracetamol was studied in nine type I and ten type II diabetics. Ten healthy volunteers served as a control group. 2. A significant increase in the elimination half-life (t1/2) and apparent volume of distribution was observed in type I diabetics compared with controls. Clearance rate (CL) was not significantly altered. 3. In type II diabetics paracetamol elimination t1/2 was significantly increased with a corresponding decrease in CL. Apparent volume of distribution of the drug was not significantly different. 4. Paracetamol elimination t1/2 had significant correlation with fasting blood sugar values.
