Filter by:Obesity in children,as in adults,has rapidly become a public health concern. Studies in adults have shown that obesity, now considered to be a disease state, is a modifier of the effect of drugs on the body as well as how the body handles the drug.The anesthetic management of obese children poses a variety of significant challenges which include determination of the appropriate dose of anesthetic intravenous agents. Dosing of most drugs is calculated based on the effective dose in 50% of patients but the more practical and required information is the effective dose in 95%(ED95%)of patients. The aim of this study is to determine the effective dose in 95% of patients(children). The hypothesis is the ED95 of propofol in obese children will be higher than that of non-obese children.
This study is designed to investigate the safety and tolerability of a new drug, AZD5363, in patients with advanced cancer - and to identify a dose and schedule that can be used in the future. This study will also investigate how the body handles AZD5363 (ie, how quickly the body absorbs and removes the drug). This study will also investigate anti-tumour activity of AZD5363 in patients with advanced / metastatic breast, gynaecological cancers or other solid cancers bearing either AKT1 / PIK3CA or PTEN mutation.
Tramadol is an opioid analgesic, which is widely used in the treatment of acute and neuropathic pain. After oral administration, tramadol is rapidly and almost completely absorbed. Tramadol is extensively metabolised by O- and N-demethylation, which are catalysed by the liver CYP-450 enzymes. O-desmethyltramadol is an active metabolite and its formation is catalysed by CYP2D6. The formation of inactive metabolites is catalysed by CYP3A4 and 2B6. This study is aimed to investigate the possible interaction of oral tramadol with itraconazole and ticlopidine, which are inhibitors of CYP3A4 and 2B6. Twelve healthy male or female adult non-smoking volunteers aged 18-40 years with body weights within ±15% of the ideal weight for height are taken into the study. Primary endpoints of the study are plasma concentrations of tramadol and its metabolites.
The primary purpose of this study is to determine whether the treatment with AZD9668 will affect the metabolism and effect of Warfarin.
Tuberculous meningitis (TBM) is the most lethal form of tuberculosis infection, and is diagnosed in approximately 5-10% of TB patients. The incidence of TBM has increased considerably during the last decade, partly due to the HIV epidemic. Without treatment, virtually all patients with TB meningitis will die. With the current treatment regimens, TBM is fatal in approximately 30-50% of cases, and responsible for severe disability in a similar proportion of survivors. Worldwide, Indonesia the third highest case load of tuberculosis with an estimated 500,000 new patients / year. Representative data are lacking, but it is clear that TBM is a growing problem. For instance, in Hasan Sadikin Hospital, the top-referral hospital for West Java Province (population 40 million), Indonesia, 40-50 cases of TBM were treated yearly in the late 90's compared to approximately 100 in recent years. There is very little evidence for the current treatment regimen for TBM, which dates back to the late 60's. Therefore, there is an urgent need to evaluate intensified treatment of TBM in randomized trials. We hypothesize that higher dose rifampicin, moxifloxacin (possibly also at high dose), or both will improve outcome of TBM. To determine the experimental regimen(s) which should be compared with current regimen in phase 3 trials, we want to evaluate pharmacokinetic aspects and toxicity of candidate regimens in a phase 2 clinical trial in 60 patients with TBM in Indonesia.
1. Background: Heparin forms a complex with a plasma protein, antithrombin III (ATIII) is an endogenous anticoagulant. This complex inhibits the formation of thrombin and accelerates its destruction. In addition, heparin and ATIII inactivate other proteases of the coagulation cascade, especially the anti-activated factor X. The outcome of these biochemical actions is the inhibition of the formation and synthesis of activators of the clotting factors that exert critical functions in the genesis of the blood clot. Patients with chronic renal failure (CRF) that make use of hemodialysis need a system of anticoagulation with direct inhibitors of thrombin and / or heparinoids to prevent thrombosis. Based on clinical studies, the control of plasma heparin level in patients with CRF is essential. Coagulation tests such as APTT, PT, ChT and evidence of activity of anti-Xa factor to be used as a substrate for protection for those patients undergoing hemodialysis. 2. Objective: Check the non-inferiority clinical, the pharmacodynamic effect and safety in use of the drug heparin of porcine origin, produced by the Laboratory Eurofarma, having as the active comparator drug APP ® Heparin Sodium (heparin - APP Pharmaceuticals) in patients with renal failure who do hemodialysis treatment.
The purpose of this study is to evaluate the effects of a chronic co-medication of efavirenz on pharmacokinetics and sterol-lowering effects of ezetimibe at steady-state in healthy subjects genotyped for ABCB1, ABCC2, CYP2B6 and UGT1A1.
This study will be investigated what mechanism of action Dienogest has. The growth of the follicles, the endometrium, the hormones in the blood and the mucus that is produced by the cervix that will be looked upon. Four different dosages of Dienogest (0.5 mg, 1 mg, 2 mg and 3 mg) will be investigated in healthy young women over two cycles, or up to a maximum of 72 days.
