Filter by:This is a Phase 1, fixed sequence, open-label study to evaluate the effect of multiple oral doses of rabeprazole on the pharmacokinetics of a single dose of vadadustat 300 mg in healthy male and female subjects.
The safety and tolerability of multiple oral administrations of GRT9906 at different doses was investigated in this clinical study. The prolonged-release tablets slowly release the active compound in the intestine. In addition, absorption into the body, distribution, metabolization and excretion of GRT9906 was characterized. Pharmacological effects of GRT9906 in healthy participants was assessed using pupillometry (diameter and reactions of the pupil) and a Cold Pressor Test where pain is measured while hands are placed in icy water for two minutes.
The purpose of the study was to investigate the pharmacokinetics (i.e. the uptake, distribution and elimination from the body) of dermally applied buprenorphine during and after different application periods, i.e., a 96-hour and a 72-hour application of the Transtec (Registered Trademark) patch (release rate 35 micrograms per hour [µg/hour]). In the Transtec summary of product characteristics (prescribing information for the physician), the wearing time per patch is restricted to three days (72 hours) after which the patch has to be replaced. However, market experience has shown that the Transtec patches are sometimes worn for a period longer than three days, i.e. they sometimes happen to be only replaced every four days. There was currently no data available as how to evaluate this longer wearing period.
Tramadol (Tradol) and ketorolac (Dolac) are marketed products to treat acute pain. This study was performed to determine if both medications can be given to a patient simultaneously without a change of the products' bioavailability.
The objective of the study was to evaluate whether or not there is a substantial pharmacokinetic interaction between diclofenac and tramadol in a new formulation of a fixed-dose combination of diclofenac 25 milligrams (mg) and tramadol 25 mg for oral administration. The study was conducted in healthy participants of both genders.
This study is being conducted in order to assess the need for dose adjustment for elafibranor in patients with hepatic impairment. Pharmacokinetic parameters of elafibranor and its active metabolite (GFT1007) will be compared in hepatic impaired patients (mild, moderate and severe according to Child-Pugh categories) versus healthy participants after a single oral administration of elafibranor 120 mg.
Introduction: The prevalence of asthma and exercise-induced bronchoconstriction is high in the athletic population. In endurance sport, the prevalence has been reported to be as high as 30-50% compared to the general population prevalence of approximately 5-10% in Western countries. First-line treatment in asthma is reliever medication and inhaled corticosteroids (ICS). Therefore, β2-adrenoceptor agonists and ICS are commonly prescribed drugs to athletes. Although long-acting β2-agonists (LABA) are the most commonly used β2-agonists in asthma management, development of ultra-long acting β2-agonists (U-LABA) as vilanterol may change this. U-LABA has a long duration of action (24 hours) compared with LABA (12 hours). The accumulated number of inhalations per day for elite athletes may thus be reduced when prescribed with U-LABA as compared to LABA. Use of β2-agonists are restricted by the World Anti-Doping Agency (WADA). As of 2018, β2-agonists salbutamol, formoterol and salmeterol are allowed by inhalation in therapeutic doses, whereas other β2-agonists, such as terbutaline and vilanterol still require the athlete to obtain a therapeutic use exemption (TUE). To discriminate therapeutic use from supra-therapeutic misuse, WADA has established urinary thresholds and decision limits based on urine concentrations of salbutamol, salmeterol and formoterol. However, while data on urine concentrations of these three β2-agonists are well-described in studies that simulate sport-specific situations that are applicable for doping control, no such data exist for the novel U-LABA vilanterol. For instance, asthmatic athletes using β2-agonists usually inhale the drug before training or competition as prophylaxis for bronchoconstriction. Thus, studies are needed to investigate the urine concentrations of vilanterol after inhaled administration in set-ups that are applicable to doping control which this study aims to investigate. Method: The study is divided in two phases. The first phase consists of a pharmacokinetic pilot trial (EXP1). Depending on the analytical outcome of the pilot study, the study proceeds into the second phase, which is a larger pharmacokinetic trial (EXP2). Both EXP1 and EXP 2 are open label studies. EXP1: 6 healthy, well trained individuals are recruited to perform two trial days. First trial day consists of inhalation of the study drug in 4 times therapeutic dose followed by an exercise session. Before second trial day subjects inhales 4 times the therapeutic dose at home and on day 7 perform a training session. Urine and blood are collected in the following 72 hours both days. EXP2: 20 healthy, well trained individuals are recruited to perform four trial days in the same way as EXP1. But here both normal use and four times normal dose is investigated.
