the bioavailability of two dipyridamol tablet formulations of (dipyridamole from tolidaru and persantin from boehringer) was compared in 14 healthy male volunteers who received a single dose of 25 mg of the test (t) and the reference (r) products in a randomized balanced 2-way crossover design. plasma samples were obtained over a 16 h interval and dipyridamole concentrations determined by hplc ...

concomitant use of several drugs by icu( intensive care unit) patients is often unavoidable. in these patients, pharmacokinetic drug interactions are very likely. the current study was designed to evaluate these interactions in patients hospitalized in an icu of a teaching hospital in tehran, iran. a questionnaire was designed and used to collect study data. the study was done in the icu of a t...

a rapid, sensitive and reproducible hplc method using amperometric detector was developed and validated for the analysis of clarithromycin in human plasma. the separation was achieved on a monolithic silica column (mz- c8 125×4.0 mm) using acetonitrile- methanol-potassium dihydrogen phosphate buffer (40:6:54,v/v), with ph of 7.5, as the mobile phase at a flow rate of 1.5 ml/min. the assay enabl...

glimepiride/metformin(2/500mg) is an oral antihyperglycemic agent for the treatment of type 2 diabetes. a generic glimepiride/metformin(2/500mg) fixed-dose combination(fdc) tablet was developed recently. this study was designed to collect data for submission to korean regulatory authorities to allow the marketing of the test formulation. we evaluated the comparative bioavailability and tolerabi...

background: vancomycin is used abundantly in patients undergoing hsct, especially during neutropenic fever. despite its widespread use little is known about vancomycin pharmacokinetics in hsct patients. we conducted this study to investigate vancomycin pharmacokinetic parameters in our hsct patients and to evaluate current dosing regimen based on trough vancomycin concentrations measurement. me...

the pharmacokinetic parameters of domestic and imported ranitidine hydrochloride tablets (ranitidine, formulated and manufactured by kharazmi pharmaceuticals, iran, and zantac ? manufactured by glaxo, uk) were measured in 14 healthy subjects following oral administration of a single 300-mg dose of each brand and compared for bioequivalence evaluation. the pharmaceutical equivalency of both form...

the aim of this study was to characterize the effect of typhoid fever on pharmacokinetic parameters of levofloxacin (lf) and compare the pharmacokinetic parameters of the said antibiotic in healthy human volunteers and patients with typhoid fever. total of 12 subjects were divided into two groups “a” (healthy volunteers) and “b” (typhoid patients). single oral dose of lf 500 mg was given and 5 ...

severe sepsis and septic shock are major problems as the result of high rates morbidity andmortality in intensive care units (icus). in the presence of septic shock, each hour of delay inthe administration of effective antibiotics is associated with a measurable increase in mortality.aminoglycosides are effective broad-spectrum antibiotics that are commonly used in icus forthe treatment of life...

Pharmacokinetic (PK) software packages are widely used by scientists in different disciplines to estimate PK parameters. However, their use without a clear understanding of physiological parameters affecting the PK parameters and how different PK parameters are related to each other may result in erroneous interpretation of data. Often, mathematical relationships used for the estimation of PK p...

BACKGROUND Omeprazole is metabolized predominantly by CYP2C19, a polymorphically expressed enzymes that show marked interindividual and interethnic variation. These variations cause a substantial differences that have been reported in the pharmacokinetics of omeprazole. The aim of the present study was to evaluate the pharmacokinetic parameters of omeprazole in a random Iranian population. ME...
