Filter by:Malnutrition and inappropriate prescribing of renally excreted drugs are common among older persons and are associated with severe consequences such as complicated courses of treatment, mortality, and reduced quality of life. The overall purpose of CanPan is to optimize treatment of older persons with malnutrition with a focus on appetite stimulation and optimized prescribing of renal risk drugs. The CanPan trial consists of two sub-studies. Substudy 1 will provide knowledge on appetite and appetite stimulation and together, sub study 1 and 2 will offer unique knowledge on how body composition, renal function and biomarkers of organ function influence pharmacokinetics for a highly lipophilic (Sativex®) and hydrophilic (Hexamycin®) drug in older medical patients with malnutrition.
Main study objective: the pharmacokinetic effects of high-fat diet on AL8326 after oral administration of AL8326 tablets in Chinese healthy adult subjects. Secondary study objectives: safety and tolerability of a single oral dose of AL8326 tablets in healthy subjects
This is a Phase I, single-center, double blind, placebo-controlled, parallel-group, randomized study designed to evaluate the PK, cardiodynamic ECG effects, safety, and tolerability of 2 single ascending oral doses of linaprazan glurate. The study will explore the PK properties of linaprazan glurate and linaprazan as well as the cardiodynamic ECG effects, safety, and tolerability after the administration of single doses (300 mg, 600 mg, 200 mg and a final dose level of maximum 400 mg) of linaprazan glurate, using 25 mg base formulation (300 mg and 600 mg doses) and 25 mg and 100 mg HCl formulation (200 mg and final dose level of maximum 400 mg) oral tablets.
The Sponsor intends to develop an intravenous (i.v.) formulation of E4 for the treatment of neonatal hypoxic-ischemic encephalopathy (NHIE). E4 has not been administered intravenously to humans yet. This single-center, double-blind, placebo-controlled randomized study aims to evaluate the safety, tolerability, and PK of an i.v. E4 solution administered as single-dose or multiple dose to healthy adult volunteers.
The purpose of this study is to optimize the dosage regimen of drugs in patients during during Extracorporeal Membrane Oxygenation (ECMO) by population pharmacokinetic modeling.
The cholesterol-lowering drug rosuvastatin is a substrate of the breast cancer resistance protein (BCRP). BCRP is an efflux transporter expressed e.g. in the small intestine. It limits the oral bioavailability of rosuvastatin by transporting rosuvastatin from enterocytes back to the gut lumen. Inhibition of BCRP can increase rosuvastatin bioavailability and systemic concentrations. Ticagrelor is a platelet aggregation inhibitor used in treatment and prevention of atherothrombotic events. Ticagrelor may inhibit BCRP in humans. This study is aimed to investigate the possible interaction of rosuvastatin with ticagrelor. Ten healthy male or female non-smoking volunteers aged 18-40 years are taken into the study. Primary endpoint is area under the plasma concentration-time curve of rosuvastatin.
Based on the tolerability, safety and pharmacokinetics phase I/II clinical trials of ulimostat hydrochloride capsules (LH011) combined with gemcitabine hydrochloride (GEM) in locally advanced/metastatic pancreatic cancer patients, to determine pharmacokinetics, the biotransformation pathway and metabolite profile of ulimostat in patients with locally advanced/metastatic pancreatic cancer.
The purpose of this study is to illustrate pharmacokinetics of sugammadex in reversal of vecuronium-induced neuromuscular blockade in patients during laparoscopic surgery
Chronic myeloid leukemia (CML) consists of 3 clinical stages including chronic phase, accelerated phase and blast crisis. Patients may only survive for few more days to weeks once the disease progresses to blast crisis, even though they might have been stable for several years in the chronic phase. The standard treatment, continuous use of tyrosine kinase inhibitors (TKIs), improves long-term survival, and even may help patients achieve complete remission. Four TKIs are reimbursed by National Health Insurance in Taiwan. Among them, imatinib, nilotinib as well as dasatinib, and ponatinib are the first, second and third generations of TKIs, respectively. Many factors influence the disease control of CML, such as TKI type, genetic mutation and medication adherence. Only 69% of patients followed their physicians' recommendations in a local survey. The medication adherence of TKIs was compromised based on several clinical studies domestically and worldwide due to the slow progression in the chronic phase. Patients might hold or decrease the dose of TKIs on their own when they suffer side effects. Furthermore, the significant intra-subject variations of TKI plasma concentration and drug-drug and drug-food interactions which alter the metabolism of TKIs may lessen therapeutic effect and patient safety. Therefore, this study aims to develop and validate analytic methods of imatinib, dasatinib, nilotinib and ponatinib plasma concentrations. The investigators plan to build the pharmacokinetic models of these 4 TKIs and analyze the impacts of meals, adherence, hepatic enzyme inhibitors and inducers, antacids, proton pump inhibitors and H2 blockers, etc. Adverse drug reactions and treatment outcomes will be evaluated to determine the availability and feasibility of therapeutic drug monitoring of TKIs as part of routine service in pharmacist-led clinics.
Preoperative antimicrobial prophylaxis is a key element for the prevention of surgical site infection, the most common type of nosocomial infection in surgical patients. Prophylactic antibiotics are selected depending on the type of surgery, and first- or second-generation cephalosporins have been mainly used. Cefoxitin, a second-generation cephalosporin with anaerobic activity, has been used in various clinical settings as a prophylactic antibiotic for colorectal surgery. Cefoxitin is generally dissolved in normal saline and intravenously administered for a short time of 5-10 minutes before skin incision. However, there are several drawbacks to the current dosing strategy. First, the dose of cefazolin is determined by a "rule of thumb", and there is controversy over whether 1 g or 2 g is appropriate, with the opinion that 2 g being more appropriate prevailing. Second, the standard administration method unnecessarily induces a concentration higher than the concentration required to prevent surgical site infection. Third, significant covariates that can affect the maintenance of MIC during surgery are not considered. The target-concentration controlled infusion (TCI) method can be a viable alternative administration method for antibiotics. The TCI method enables individual customized administration according to the covariates (i.e., weight, creatinine clearance) included in the pharmacokinetic parameters; also, although with some variability, the drug can be administered while maintaining the target concentration. The aim of this study was to evaluate the effectiveness of administering cefoxitin in patients undergoing colorectal surgery with a syringe pump equipped with a target concentration control injection function
