Effect of coingestion of paracetamol on glycaemic response.

Rate of gastric emptying is a frequently measured variable in glycaemic response studies. One of the indices employed for measurement of the gastric emptying rate is the blood level of paracetamol at frequent intervals of time following coingestion of paracetamol with the meal. But the effect of paracetamol itself on glycaemic response is not known. The present study was performed on ten healthy and five NIDDM subjects. Each subject underwent two meal tolerance tests in random sequence. On one occasion the meal was white bread; on the other occasion, the meal consisted of the same quantity of white bread and 1.5 g paracetamol. The postprandial glycaemica following the two meals was not significantly different. Thus the results validate the use of the paracetamol technique for gastric emptying in glycaemic response studies.
