The pharmacokinetics of cefotiam were investigated after intravenous administration of 1 g to 2 healthy volunteers with normal renal function and to 16 patients whose creatinine clearance ranged from 4.7 to 0.1 l/h (78 to 1.66 ml/min). The elimination half-life varied from 1.1 h in normal subjects to 13 h in patients and the total plasma clearance from 21(More)
Sulfinpyrazone kinetics has been investigated after intravenous and oral doses. They may be described by a 3-compartment open model. In the body about half the drug is in the plasma or in interstitial fluids, which equilibrated with plasma. Most of the rest is in an extravascular compartment, from which it easily diffuses back to the plasma. About 3% of the(More)
The possible influence of the concomitant administration of cefotiam and cefsulodin on their respective pharmacokinetics was studied in 15 patients with renal insufficiency and 10 anuric patients. Linear relations were found between the clearance of creatinine and the total clearance, as well as the renal clearance, of each drug. These relations for each(More)
The diffusion of oxyphenbutazone into synovial and cerebrospinal fluids and synovium and joint cartilage was investigated in 25 patients receiving short-term treatment. In the synovial fluid, the mean oxyphenbutazone concentration, was 57.1±13.4% of the plasma level, due to its excellent diffusion into the joint cavity. In synovial tissue, the(More)
The influence of nutrients and digestive secretions on the intestinal absorption and bioavailability of the beta-adrenoceptor antagonist, metoprolol, was investigated in an isolated segment of jejunum using an intestinal perfusion technique. Two solutions containing metoprolol, one with, and one without nutrients, were perfused into the jejunum with an(More)
After intravenous bolus injections of 0.5, 1, and 2 g of cefotiam to three healthy volunteers, the mean (+/- standard deviation) total plasma clearances measured for each dose were, respectively, 26.8 +/- 2.7, 22.8 +/- 0.8, and 17.8 +/- 0.9 liters/h; the terminal elimination half-lives were 54.0 +/- 0.1, 68 +/- 15, and 98 +/- 36 min; and the renal(More)
