1,7-dimethylxanthine has been researched along with Liver Cirrhosis in 6 studies
1,7-dimethylxanthine : A dimethylxanthine having the two methyl groups located at positions 1 and 7. It is a metabolite of caffeine and theobromine in animals.
Liver Cirrhosis: Liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules.

| " 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." | 5.28 | A simple useful method for the determination of hepatic function in patients with liver cirrhosis using caffeine and its three major dimethylmetabolites.
