Abstract Introduction: Bioequivalence studies are the most important way of evaluating the quality and efficacy of pharmaceutical formulations. In a bioequivalence study, the rate and extent of drug absorption into the general circulation is measured and the pharmacokinetic parameters should be calculated and statistically evaluated for the reference and test products. Pharmacokinetic paramete...
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 fo...

the pharmacokinetic properties of amoxicillin and clavulanic acid when used alone or in combination may be different and show interaction between these two agents that might decrease the absolute bioavailability of clavulanic acid. in an open, randomized, replicated latin square under fasting condition, pharmacokinetics of new formulations of amoxicillin/clavulanic acid were compared with a ref...
Bayesian estimation enables the individual pharmacokinetic parameters of the medication administrated to be estimated using only a few blood concentrations. Due to wide inter-individual variability in the pharmacokinetics of methotrexate (MTX), the concentration of MTX needs to be frequently determined during high-dose MTX therapy in order to prevent toxic adverse events. To apply the benefits ...
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...
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 ...
BACKGROUND Hydroxyethyl starches (HES) accumulate in the circulation when administered repeatedly. Accumulation is thought to be partly responsible for undesirable effects (tissue storage, blood coagulation impairment, and itching). HES 130/0.42 with low molecular weight and a low level of substitution has recently been developed in order to reduce those risks. METHODS In healthy volunteers, ...
The population pharmacokinetics on tazobactam/piperacillin (TAZ/PIPC; 1:8, 4.5 g x 3) was analyzed in Japanese patients with community-acquired pneumonia using the Nonlinear Mixed Effect Model version VI. Analysis by the one-compartment model yielded the following results for PIPC: total clearance (CL) = 8.22+(Ccr-71.4) x 0.0561 (L/hr), distribution volume (Vd) = 13.7 (L). The pharmacokinetic p...
