[Theopek absorption efficiency in chronic diseases of the large intestine]

A total of 10 patients with chronic ulcerative colitis (CUC) were examined. The patients took a single dose of theopec (300 mg). The patients with chronic obstructive lung diseases (COLD) without intestinal disorders served as controls. Blood theophylline concentrations were measured by high performance liquid chromatography. The absorptive efficiency of theopec was comparatively evaluated in patients with CUC and those with COLD without intestinal disorders. The use of the drug in patients with CUC resulted in the unneeded high serum theophylline concentrations.
