Filter by:The purpose of the study is to investigate the pharmacokinetics of oral dosage of Posaconazole which is routinely administered as a standard care prophylaxis for patients undergoing cancer treatments.
To evaluate the safety and pharmacokinetics of GV-971 capsules after oral a single or multiple doses of 900 mg, 1200 mg and 1500 mg in healthy subjects.
This investigation is intended to collect safety information for the technique of mixing cefazolin in the CRRT solution on the CRRT circuit, the patient, in addition to collecting information regarding the ability to obtain therapeutic cefazolin serum concentrations
This is a single-dose and multiple-dose, open-label, single-centre pharmacokinetic (PK) study which will be conducted in Phase I Clinical Trial Centre, Chinese University of Hong Kong, to evaluate pharmacokinetics (PK) of different levels of single-dose and multiple-dose of bilastine in healthy Chinese subjects.
The study start on June 30, 2018. The Severe(F Ⅷ<1%) hemophilia A children without F Ⅷ inhibitor combining were recruited to Test the concentration of the drug in the blood to provide better treatment.
Multidrug resistance towards Gram-negative pathogens makes essential the re-examination of older compounds. Temocillin is a penicillin originally marketed in the 1980s but then largely abandoned. It, however, shows a marked ß-lactamase stability (including most classical and extended-spectrum TEM, SHV, CTX-M enzymes and AmpC ß-lactamase). Temocillin is approved for the treatment of bacterial infections of the chest, the lungs, the kidney, the bladder, as well as bacterial infections of the bloodstream and wound infections. Temocillin efficacy depends primarily from the time interval during which the unbound plasma concentration remains above the minimal inhibitory concentration (MIC) of the antibiotic against the target organism(s). Unfortunately, no comprehensive pharmacokinetic data are available in non-critically-ill patients. The primary objective of the study is characterize the pharmacokinetics of total and unbound temocillin in non-ICU patients, and, on this basis, to propose optimized dosage regimens in this population. The secondary objectives are (i) to look for possible correlations between the plasma protein profile and the unbound temocillin concentrations; (ii) to investigate the impact of the level and nature of circulating plasma proteins on the unbound temocillin concentration. The study will be non-randomized, uncontrolled, prospective, open label, interventional, and monocentric. It will include a population pharmacokinetic-pharmacodynamic analysis of the data obtained. The study will enroll patients ≥ 18 years in need of a treatment with temocillin for (i) complicated urinary tract infection and pyelonephritis (associated or not with bacteremia), or (ii) lower respiratory tract infection, or (iii) abdominal infection, and requiring ≥ 4 days of hospitalization. Blood samples will be obtained at day 0 (control) and after 2 and 4 days of drug treatment (full pharmacokinetic evaluation over 8 to 12 h post-administration). Total and unbound temocillin concentrations in plasma will be quantified by a validated analytical method. A population pharmacokinetic/pharmacodynamics model of plasma total and unbound concentrations of temocillin will be obtained by Bayesian algorithms using Pmetrics software, driven by the predicted plasma total and unbound concentration. The model will be used to assess the probability of target attainment of temocillin.
A randomized, open-label, active-controlled, single/multiple-dose phase 1 clinical trial to evaluate pharmacokinetics/pharmacodynamics and safety/tolerability of tegoprazan after oral administration in healthy male subjects
This prospective study will compare the pharmacokinetic exposure to liposomal amphotericin B between critically ill patients and non-critically ill (hematology) patients in an early and late exposure day.
Antibiotics are still most often administered on an empiric fashion, as defined for the general population with dosages only adapted based on weight and renal and/or hepatic functions. As a result, serum concentrations show important interpatient variations with the risk of being subtherapeutic or toxic. Recent studies with temocillin, ceftriaxone, or meropenem confirm this for patients in intensive care units. The aim of the study will be to measure the total and free concentrations of temocillin, ceftriaxone, and meropenem in patients hospitalized in Intensive Care Units for pulmonary infections or another infection for which one of the above mentioned antibiotics is indicated. Patients will be stratified according to the level of their renal function. The antibiotics will be assayed in plasma as well as other accessible fluids in order to assess their pharmacokinetic properties.
The time course of bisphenol S in plasma and urine will be monitored in female adults exposed to a single oral and dermal dose of bisphenol-S. Six female will be recruited. Blood and urine will be collected at specified times post-treatment. Bisphenol concentrations will be measured in those samples.
