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. met...
This study was conducted to comprehensively survey the available literature on intravenous pharmacokinetic parameters in the rat, dog, monkey, and human, and to compare common methods for extrapolation of clearance, to identify the most appropriate species to use in pharmacokinetic lead optimization, and to ascertain whether adequate prospective measures of predictive success are currently avai...
There has been certain criticism raised by A. Rescigno [2,8,9,12-15] against the standard formulation of pharmacokinetics. In 2011 it has been suggested that inconsistencies in pharmacokinetics should be eliminated after deriving “pharmacokinetic parameters” from conservation laws [3]. In the following text a simple system of conservation laws for extra vascular administration of a drug is expl...
Pharmacokinetic (PK) parameters of marbofloxacin (MRFX) in Korean cattle, Hanwoo, were determined following its intravenous (i.v.) or intramuscular (i.m.) administration at a dose of 2 mg/kg. Area under the curve (AUC0-24 hr), half-life (t1/2) and total body clearance (CLB) of i.v. MRFX were 6.87 hr∙µg/ml, 2.44 hr and 0.29 l/kg∙hr, respectively, and the corresponding values for i.m. administrat...
In this paper, the problem of interest is efficient estimation of log-normal means. Several existing estimators are reviewed first, including the sample mean, the maximum likelihood estimator, the uniformly minimum variance unbiased estimator and a conditional minimal mean squared error estimator. A new estimator is then proposed, and we show that it improves over the existing estimators in ter...
Background and purpose: Pulmonary arterial hypertension (PAH) is a fatal disease affecting patients in all ages that could result in acute and chronic heart failure with high mortality rate. Oral sildenafil is approved to treat PAH in adults and recently in children. There are limited studies on the pharmacokinetics parameters of sildenafil, therefore, this study was designed to determine the p...
immunosuppressants require therapeutic drug monitoring because of their narrow therapeutic index and significant inter-individual variability in blood concentrations. this variability can be because of factors like drug-nutrient interactions, drug-disease interactions, renal-insufficiency, inflammation and infection, gender, age, polymorphism and liver mass. drug monitoring is widely practiced ...
