[Pharmacokinetics of n-(5-oxynicotinoyl)-L-glutamic acid calcium salt upon bolus administration in rats and rabbits: interspecies extrapolation].

The pharmacokinetics of N-(5-oxynicotinoyl)-L-glutamate (ONG) was studied in rats (doses, 20, 100 and 500 mg/kg) and rabbits (50 mg/kg) after bolus administration of calcium salt of N-(5-oxynicotinoyl)-L-glutamic acid (Ampasse preparation). The ONG concentration in the blood serum was determined by HPLC assay with fluorimetric detection. The lower limit of accurate detection for ONG was 100 ng/ml.

Carotid endarterectomy without angiography.

Between 1 January 1990 and 1 September 1994 a total of 109 carotid endarterectomies were performed without preoperative angiography. Only two cases were considered by the surgeon to have a poor correlation between the duplex examination results and intraoperative findings; the outcome was good in both. The perioperative mortality rate was 1.

[Age-related characteristics of ceftazidime pharmacokinetics in children].

To reveal possible age-dependent variations in the ceftazidime pharmacokinetics, the drug plasma concentrations were determined by HPLC in 10 children aged 2 to 13 years with peritonitis. The blood specimens were collected 0.25, 0.

[Individualization of the amikacin administration regimen on the basis of the relationship between its pharmacokinetics and the patient's status].

Dosage individualization based on quantitative relationships between pharmacokinetic parameters and anatomophysiological and/or pathological factors, patient's factors (PFs) is of importance in designing optimal regimens. Unfortunately, the attempts to correlate aminoglycoside pharmacokinetic parameters and PFs often failed perhaps due to insufficient numbers of PFs under investigation. That is why we sought to involve more PFs, especially nontraditional ones, for explaining intersubject variability of the amikacin model-independent parameter in 20 patients with purulent inflammatory processes.
