"The study group consisted of 7 patients with compensated liver cirrhosis and 10 healthy volunteers, all individuals were given a single 280 mg dose of caffeine perorally."7.71[Use of the paraxanthine/caffeine ratio in the saliva of patients with liver cirrhosis]. ( Perlík, F; Pucelíková, T; Slanar, O, 2001)
"Apparent pharmacokinetic parameters of caffeine elimination from the circulation were determined in 27 patients with histologically confirmed liver cirrhosis, 8 patients with miscellaneous liver disease, and 8 patients with other than liver disease."7.67Correlation of caffeine elimination and Child's classification in liver cirrhosis. ( Gerok, W; Haag, K; Holstege, A; Staiger, M, 1989)
" These findings suggest that CA pharmacokinetic parameters can be estimated using a simplified three-point blood sampling procedure following a single oral load and that the serum PX/CA or (PX + TB + TP)/CA ratio in a single blood sample taken 2 or 4 h after dosing provides a useful indicator for the assessment of hepatic drug-oxidizing capacity, N-demethylation, in decompensated liver cirrhosis."5.28A simple useful method for the determination of hepatic function in patients with liver cirrhosis using caffeine and its three major dimethylmetabolites.
