Filter by:Young and elderly, male and female subjects are each given 2 different doses of mirabegron for 7 days each. Levels of mirabegron in the blood are assessed.
To explore what is driving heart-rate increases after dosing with mirabegron. Subjects will be given a beta-blocker at the same time as mirabegron.
The purpose of this study is to evaluate the systemic exposure of BDP, its metabolite beclomethasone 17-monopropionate (B17MP) and formoterol after inhalation of BDP/Formoterol 100/6 µg pMDI combination (CHF1535) using the standard actuator and charcoal block technique or using a Spacer (AeroChamber Plus, Trudell) in comparison with inhalation using the standard actuator
This is a Phase 1, single-center, open-label, randomized, 3-period, 2-sequence crossover study of GDC-0973 in healthy subjects to evaluate the effect of the proton pump inhibitor (PPI) rabeprazole on the relative bioavailability of GDC-0973 in healthy subjects when administered in the fed or fasted states.
This is a single dose study of radiolabeled [14C]-LY2452473 in healthy male volunteers to study the absorption, distribution, metabolism, and elimination of LY2452473. This study is for research purposes only and is not intended to treat any medical condition.
The purpose of this study is to evaluate the bioequivalence of a 100-mg tapentadol (CG5503) dose administered as two 50-mg ER, TRF tablets relative to one 100-mg ER TRF tablet in healthy Japanese male participants.
The purpose of this study is to evaluate the bioequivalence of a 50-mg tapentadol (CG5503) dose administered as two 25-mg ER, TRF tablets relative to one 50-mg ER TRF tablet in healthy Japanese male participants.
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. However, the pharmacokinetic profile of red yeast rice capsule (LipoCol Forte)is still unknown. The objective of the study is to evaluate the pharmacokinetic profile of red yeast rice capsule (LipoCol Forte) after administering single and multiple dose to healthy subjects.
Background: - Magnetic resonance imaging (MRI) is a widely used scanning technique to obtain images of the human body and evaluate activity in the brain. A particular MRI method called magnetic resonance spectroscopy (MRS) can be used to study brain chemistry as well, which may help researchers who are studying new treatments for psychiatric illnesses. Researchers are interested in improving current MRI and MRS techniques, as well as developing new MRI and MRS techniques to view and measure brain chemicals and brain activity. Objectives: - To implement, develop, and optimize brain chemistry imaging techniques using magnetic resonance imaging and magnetic resonance spectroscopy. Eligibility: - Healthy individuals between 18 and 65 years of age. Design: - This study will involve a screening visit and a scanning visit at the National Institutes of Health Clinical Center. - Participants will be screened with a full medical and physical examination, blood and urine tests, and neurological testing. - During the second visit, participants will have an MRI scan of the brain. (Participants who have received an MRI within the past year will not need to have a second one; the images of the previous scan will be used for this study.) All participants will then have an MRS scan using the same scanning equipment.
During alveolar hypoxia, for example at high altitude or in patients with respiratory disease, there is evidence to suggest that hypoxia-induced pulmonary hypertension might limit exercise performance. Intravenous iron supplementation has recently been shown to reverse pulmonary hypertension in healthy humans at high altitude, and to prevent pulmonary hypertension in volunteers exposed to hypoxia at sea level. The investigators hypothesized that intravenous iron supplementation would enhance exercise capacity during alveolar hypoxia.
