Filter by:The primary objective of this study is to evaluate whether ASA, the combination of ASA and clopidogrel, and darexaban, which have different effects on blood coagulation, influence each other in their effects. Also it will be investigated whether the blood levels of either drug are influenced by the presence of the other drug. In addition, the safety and tolerability of each drug and the combination of the drugs will be investigated.
The primary objective of this study is to evaluate whether naproxen and darexaban which have different effects on blood coagulation influence each other in their effects. Also it will be investigated whether the blood levels of either drug are influenced by the presence of the other drug. In addition, the safety and tolerability of each drug and the combination of the drugs will be investigated.
The objective of this study is to evaluate pharmacokinetics, in particular the routes of excretion and extent of metabolism of ASP015K after a single oral dose of 14C-labeled ASP015K.
The primary objective of this study is to determine the effect of rifampicin on the way the body handles darexaban and its metabolites (drug degradation products). The secondary objective of the study is to evaluate the safety and tolerability of a single dose of darexaban alone and when administered together with rifampicin.
The primary objective of this study is to determine the effect of ketoconazole on the blood concentrations of darexaban and its metabolites (drug degradation products). The secondary objective of the study is to evaluate the safety and tolerability of a single dose of darexaban alone and when administered together with ketoconazole.
The investigators investigate the effect of Chungkookjang on histamine-induced skin reaction in a double-blind, randomized, placebo-controlled, human trial
The objectives of this study are to assess the safety and effectiveness of the SENSIMED Triggerfish® (TF) device in continuous recording of relative fluctuation in intraocular pressure (IOP). Safety will be assessed by recording of AEs during the 24 hours of continuous TF recording. TF efficacy will be evaluated by demonstrating TF ability to detect: 1. The known phenomenon of increase in IOP when moving from waking state to going to bed, as reflected in pneumotonometer measurements 2. Ocular Pulse frequency relative to direct measurement of Heart Rate (HR). A screening visit and one 24-hour IOP fluctuation recording session are planned for each patient. IOP fluctuation recording sessions will be carried out in a sleep unit. An ophthalmological examination of the eyes will be done at screening and prior to and following the device recording.
The genetic factors associated with variability in CYP2C9 induction have not been elucidated. The hypothesis underlying this study is that following 7 days treatment with rifampicin, a known CYP450 inducer, the genetic variability in regulatory elements controlling CYP2C9 expression will be associated with the magnitude of change in INR response to warfarin and in CYP2C9-mediated warfarin metabolism.
The objective of the study is to explore safety and tolerability of single ascending doses of ASP015K, establish the maximum tolerated dose, and determine the pharmacokinetics and pharmacodynamics in healthy volunteers.
Red yeast rice capsule (LipoCol Forte)is a nature product that has been demonstrated a significant cholesterol lowering effect which might be caused by addictive and/or synergistic effects of lovastatin (monacolin K) with other monacolins and substances in capsules. The usual dose of red yeast rice capsule(LipoCol Forte)for hypercholesterolemia is one capsule twice/day. Gemfibrozil is a fibric acid derivative (fibrate). It can reduce the levels of triglycerides and increase the levels of high-density lipoprotein cholesterol (HDL-C). Patients with mixed lipid disorders may therefore benefit from a combination of a statin and a fibrate. Although the combination of a fibrate and a statin is highly effective,concerns about an increased incidence of myopathy and even rhabdomyolysis have limited the widespread use of such combinations. Such combination therapies are prone to drug-drug interactions, which can lead to altered pharmacokinetic profiles of either drug, an effect observed for many statins in combination with fibrates. However, the drug-drug interactions have not been reported between red yeast rice capsule and gemfibrozil. The objective of the study is to evaluate the effect of gemfibrozil on the plasma concentrations of lovastatin and its active form, lovastatin acid, from red yeast rice capsule in healthy volunteers. In addition, the investigators also measure the plasma concentration of creatine kinase (CK) and co-enzyme Q10 for safety assessment.
