Influence of renal function on the pharmacokinetics of diacerein after a single oral dose.

The pharmacokinetics of diacetylrhein following a single oral dose of 50 mg was studied in 12 healthy volunteers and two groups of 8 patients with mild or severe renal insufficiency. Statistical analysis using a Kruskal-Wallis rank sum test showed a significant difference between the three groups for the following parameters. In severely uraemic patients, median AUC0-infinity was multiplied by a factor of about 2: 40.

Influence of renal function on the pharmacokinetics of diacerein after a single oral dose.

The pharmacokinetics of diacerein (a new anti-inflammatory analgesic antipyretic drug) following a single oral dose of 50 mg was studied in 12 healthy volunteers and two groups of eight patients with mild or severe renal insufficiency. Statistical analysis using a Kruskal-Wallis rank sum test showed a significant difference between the three groups for the following parameters. In severely uraemic patients, median AUC0-infinity was multiplied by a factor of ca 2: 40.

[Determination of mannitol and lactulose in urine by capillary gas chromatography].

Gas capillary chromatography (GCC) determination of mannitol and lactulose in urine after oral intake is a method for assessing the intestinal permeability in various bowel diseases. The method proposed, using gas capillary chromatography with flame ionization detection after silylation of urine residue, gives good results: coefficients of variation varied from 6 to 8.7% for mannitol and 7.
