## Abstract The metabolism and pharmacokinetics of intravenously administered theophylline (100 mg) have been investigated in three healthy male volunteers who consumed 6 bottles day of a cola beverage, in addition to their usual intake of methylxanthines, for 7 days prior to and during the study.

โฆ Synopsis
The influence of caffeine (60 mg) was studied on the pharmacokinetic characteristics of acetaminophen (500 mg single dose) in ten healthy male human volunteers in a complete cross-over design. A high-performance liquid chromatography (HPLC) method was used to analyse serum drug concentrations. Caffeine caused a highly significant (p < 0.01) increase in AUC and AUMC, a significant (p < 0.05) increase in C-, and a significant (p < 0.05) decrease in clearance (Cl/F) of acetaminophen. We conclude that caffeine taken in doses commonly available commercially or in a cup of coffee can significantly potentiate the therapeutic potential of acetaminophen in man.
