چکیده
CĂlem prĂĄce bylo stanovit koncentraci ampicilinu v plazmÄ kardiochirurgickĂ˝ch pacientĹŻ podstupujĂcĂch revaskularizaci myokardu bez pouĹžitĂ extrakorporĂĄlnĂho obÄhu a vĂ˝poÄet jeho zĂĄkladnĂch farmakokinetickĂ˝ch parametrĹŻ. Ke stanovenĂ koncentrace byla zavedena validovĂĄna HPLC metoda s UV detekcĂ vyuĹžitĂm kolony Luna® Omega Polar C18 Column (250 Ă 4 mm; 5 µm). IndividuĂĄlnĂ farmakokinetickĂŠ parametry byly vypoÄteny programu MW Pharm 3.30 za jednokompartmentovĂŠho modelu. PlazmatickĂŠ mÄĹeny u 20 15, 30, 45, 60, 120 180 min po podĂĄnĂ pĹi ukonÄenĂ operace. Byla zjiĹĄtÄna prĹŻmÄrnĂĄ Cmax 127 ± 49 mg/l, poloÄas eliminace 77 29 min, celkovĂĄ clearance 191 73 ml/min distribuÄnĂ objem 19 l. VypoÄtenĂ˝ prĹŻmÄrnĂ˝ Äas, ve kterĂŠm plazmatickĂĄ klesla k pĹedpoklĂĄdanĂŠ prahovĂŠ hodnotÄ ĂşÄinnosti (1 mg/l), byl 8,5 3,5 h.

Plasma concentrations of enrofloxacin after single-dose oral administration in loggerhead sea turtles (Caretta caretta).
Plasma concentrations and pharmacokinetics of enrofloxacin were determined in 12 loggerhead sea turtles (Caretta caretta) after oral administration. Six turtles in group 1 and group 2 received enrofloxacin at 10 mg/kg and 20 mg/kg of body weight, respectively. Blood was collected from the cervical sinus before administration and at timed intervals up to 168 hr following administration. Plasma c...
متن کاملRapid, precise, turbidometric assay for low levels of ampicillin in serum after single-dose oral administration.
A turbidometric assay is described for the quantitative measurement of ampicillin in serum. Standard curves prepared with known concentrations of ampicillin in serum exhibited acceptable linearity over a concentration range of approximately 0.2 to 1.8 mug/ml. Data are presented to show the excellent precision of the assay and the application of the assay to clinical studies. The advantages of t...
متن کاملAntibiotic prophylaxis for cardiac surgery.
Antibiotic prophylaxis for cardiac surgery is a controversial area. Recent systematic reviews and meta-analyses of randomized controlled trials have concluded that surgical site infection can be reduced by prolonging prophylaxis for 24-48 h. Also, post-operative pneumonia and all-cause mortality can be reduced by giving agents with both anti-Gram-negative and anti-Gram-positive activity. The ch...
متن کاملAmpicillin concentrations in human dental granuloma after a single oral administration of talampicillin.
Ampicillin concentrations in human serum and dental granulomas of 31 patients were determined after a single oral dose of talampicillin (equivalent to 500 mg of ampicillin) was administered to each. The specimens were taken at 1.5, 2.0, 2.5, 3.0, and 3.5 h after the administration of talampicillin. The mean peak ampicillin concentrations in serum and dental granulomas occurred at identical time...
متن کاملPlasma atropine concentrations determined by radioimmunoassay after single-dose i.v. and i.m. administration.
The plasma concentrations of atropine following i.v. or i.m. administration to surgical patients were determined by radioimmunoassay. When atropine sulphate 1 mg was given i.v. there was a rapid initial removal of the drug from the circulation in the first 10 min; thereafter the plasma concentration decreased more slowly. Atropine i.m. was rapidly absorbed with peak concentrations occurring at ...
