Filter by:In this prospective monocenter observational study, the objective was to determine a safe and effective therapeutic window for cefepime in patients with neutropenic fever.
This study is designed to assess pharmacokinetics and pharmacodynamics of evolocumab and alirocumab across an appropriate dose range to inform clinical trial operating characteristics for future clinical pharmacology pharmacodynamics similarity studies. This is a randomized, placebo-controlled, single-dose, parallel arm study in 72 healthy subjects assigned to one of four dose groups (low, intermediate low, intermediate high, and high) of each drug (evolocumab and alirocumab ) or placebo.
This study is designed to assess pharmacokinetics and pharmacodynamics of interferon beta-1a and peginterferon beta-1a across an appropriate dose range to inform clinical trial operating characteristics for future clinical pharmacology pharmacodynamics similarity studies. This is a randomized, placebo-controlled, single-dose, parallel arm study in 84 healthy subjects assigned to one of three dose groups (low, intermediate, and high) of each drug (interferon beta-1a and peginterferon beta-1a) or placebo.
This study is designed to assess pharmacokinetics and pharmacodynamics of mepolizumab and reslizumab across an appropriate dose range to inform clinical trial operating characteristics for future clinical pharmacology pharmacodynamics similarity studies. This is a randomized, placebo-controlled, single-dose, parallel arm study in 72 healthy subjects assigned to one of four dose groups (low, intermediate low, intermediate high, and high) of each drug (mepolizumab or reslizumab) or placebo.
The purpose of this study is to illustrate pharmacokinetics and pharmacodynamics of sugammadex in reversal of vecuronium-induced neuromuscular blockade in anesthesia obese patients undergoing bariatric surgery.
Smokers are at higher risk of developing Erectile dysfunction (ED) independent of age and comorbidities. Sildenafil is a cytochrome p3A4 (CYP3A4) substrate used for enhancing the erectile function in males. The study purpose is to determine the effect of smoking on male sexual function based on the international index of erectile function score (IIEF) and investigate the effect of smoking (Cigarettes or marijuana) on the pharmacokinetics and pharmacodynamics of sildenafil.
An Open-label, One way, Two period Comparative study To Determine The effect of Morning Versus Evening administration of Empagliflozin 10mg on Its Pharmacokinetics And Pharmacodynamics in Healthy Adults
Demand for anesthesiologists outside the operating rooms is increasing. Surgeons, radiologists, endoscopists and other interventionists are performing procedures with greater complexity, sometimes accompanied by greater pain and therefore require some sedation. This growing need place a pivotal role on careful handling the delivered drugs. Specifically, the investigators wish to know how different classes of drugs interact in order for us to titrate the effects more precisely. Early studies used isobolograms and concentration effect curves as their tools but these methods are limited and incapable of making continuous bedside monitoring. Researchers integrated these methodologies mathematically and developed response surface models. It's becoming a very convenient tool to assess drug interactions. Drug interactions are visualized with a three dimensional graph, or a surface. Users will only need the calculated drug concentrations and a predicted loss of response probability will be given after a model is built. The process of model construction is complex and time demanding process. Our team has successfully built a dual-drug model for midazolam and alfentanil and several works have been published in renowned anesthesia journals. Dual-drug models are simple but their use is very limited. The investigators often use more than two drugs during practice and a three-drug model will be a great leap to monitor clinical pharmacodynamics. The investigators will collect vital signs, anesthestic depth (BIS=bispectral index, analgesia nociception index (ANI)), drug dosing (propofol, midazolam and alfentanil), and the MOAA/S (modified observer's assessment/alertness score) scores in patient who are receive routine general anesthesia under laryngeal mask or sedation for TEE (transesophageal echocardiography) examinations. Patient's consent will be obtained prior to enrollment. These recordings will be pooled into computer program for model construction. A novel model in the field of anesthesia was chosen and modified. As pioneers in this field in Taiwan, the investigators plan to perform a series of analysis using a novel model the investigators have built to look into detail on how drugs interact with each other. A safety boundary to avoid excessive respiratory depression can be drawn by the model. The main goal is to provide sedation that gives precision, patient comfort, rapid return of consciousness and safety based on the triple-drug response surface model.
