Pharmacokinetics of antibiotics in critically ill neonates, infants and children on extracorporeal membrane oxygenation (ECMO).
Blood concentrations of Ciprofol were measured at different time points after single injection in patients with hypoproteinemia
A DDI study consisting of 3 parts conducted as an open label, fixed sequence study in healthy adult subjects.
This study is designed to determined the metabolism, excretion, and substance balance of almonertinib of ADC189. The pharmacokinetic characteristics and safety profile of ADC189 was investigated following a single oral dose (45 mg/100 µCi) in healthy Chinese male participants.
The goal of this a clinical trial is to learn about the efficacy，safety and Pharmacokinetics of Hepenofovir Fumarate Tablets（HTS） in patients with CHB. The main questions it aims to answer are： 1. Evaluate the efficacy and safety of multiple doses of continuous administration of HTS in patients with chronic hepatitis B, and compare it with Tenofovir alafenamide Fumarate tablets（TAF）. 2. To evaluate the pharmacokinetic characteristics of HTS in patients with chronic hepatitis B after multiple oral administration. 3. To evaluate the pharmacodynamic changes of HTS in patients with chronic hepatitis B after multiple consecutive administrations, and compare it with TAF. Positive control drug：Tenofovir alafenamide Fumarate tablets（25mg/d） Test drug：Hepenofovir Fumarate Tablets（10mg/d、20mg/d、40mg/qod） Test process：This study was divided into 4 groups, with the specific list shown below. The initial plan was to include 12 subjects in each group, stratified by HBeAg status, with 4 subjects negative for HBeAg and 8 subjects positive for HBeAg. A total of 48 subjects were included in this trial, and they were randomly assigned to multiple doses at a ratio of 1:1:1:1. The dosing period was 24 weeks. However, after enrolling 37 subjects (29 positive for HBeAg and 8 negative for HBeAg), the protocol was adjusted (V4.0): the remaining 11 subjects would be included, all of whom were over 30 years old with ALT < ULN and met all the inclusion criteria but none of the exclusion criteria. The random assignment was: 7 subjects positive for HBeAg were randomly assigned to HTS 10mg/day, 20mg/day, 40mg/qod and TAF 25mg/day groups at a ratio of 2:2:2:1; and 4 subjects negative for HBeAg were randomly assigned to HTS 10mg/day, 20mg/day, 40mg/qod and TAF 25mg/day groups at a ratio of 1:1:1:1.
To evaluate the systemic pharmacokinetics and the safety of atropine sulfate eye drops in healthy volunteers.
The purpose of this study is to evaluate the therapeutic efficacy expressed in pharmacokinetic/pharmacodynamic (PK/PD) indices, the clinical response and the risk of adverse reactions following the continuous and intermittent administration of linezolid in critical patients in the Intensive Care Unit. Subject inclusion criteria: A minimum of 30 subjects in each group will be included in the study, in accordance with the study inclusion criteria: - patients hospitalized in the intensive care unit, - female or male sex, - age over 18 years, - linezolid is prescribed by the attending physician, in empirical or targeted treatment Exclusion criteria: Patients who have documented severe liver failure (Child-Pugh C score). Patients who refuse to sign the informed consent
This study is based on the hypothesis that the pharmacokinetics of fluconazole in newborns and children are different from adults. We aim to study the population pharmacokinetics of newborns and children receiving the fluconazole for treatment of infectious diseases. In this study, we will detect fluconazole concentration in plasma by using residual blood samples of blood gas analysis and other clinical tests and employ computers for constructing population pharmacokinetic models. In addition, we also want to correlate use of fluconazole with treatment effectiveness and incidence of adverse effects in newborns and children. This novel knowledge will allow better and more rational approaches to the treatment of infectious diseases in newborns and children. It will also set the foundation for further studies to improve fluconazole therapies for newborns and children.
Protein-bound uremic toxins (PBUTs) are important uremic toxins, represented by indoxyl sulfate (IS), derived from the fermentation of dietary proteins by gut bacteria. The purpose of this study was to study the changes of IS in maintenance hemodialysis patients, and to construct a metabolic kinetics model of IS clearance. The model was then used to estimate the clearance rate of indoxyl sulfate by hemoperage, and to verify the application value of the model. This study intends to collect a series of serum, dialysate and urine samples from maintenance hemodialysis patients receiving high-throughput dialysis or hemodialysis filtration, so as to clarify the variation rule of IS during various blood purification treatments. Furthermore, a three-compartment model of dialysis IS metabolism kinetics was constructed according to the IS clearance of dialysis and residual kidney, and the above model was verified internally and externally. Finally, the model's fit and predictive value were validated in a group of MHD patients treated with HP without residual kidney.
