Filter by:The purpose of this study is to investigate if the drugs rifampin and fluconazole when given together increase the concentrations in the body of the oral diabetes medication glyburide.
This study is being conducted to see if neratinib is absorbed, distributed, or eliminated differently when administered in the fasting state versus after a high-fat meal.
The purpose of this study is to serve as a pilot safety study for nasal allergen challenges.
The main purpose of this research study is to evaluate the effect of multiple doses of an investigational drug known as JNJ-31001074 on the single dose of combination oral contraceptive Ovral-L containing ethinyl estradiol and levonorgestrel in healthy women who cannot bear children. This study will look at the safety, tolerability (how the drug makes you feel) and pharmacokinetics (what your body does to the drug) of either drug alone and in combination in healthy women.
Autoregulation is the ability of a vascular bed to maintain blood flow despite changes in perfusion pressure. The existence of an effective autoregulation in the optic nerve head (ONH) circulation has been shown in animals and humans. Moderate elevation of intraocular pressure (IOP) caused only slight effect on ONH blood flow in monkeys, cats and rabbits. In humans, during an artificial IOP rise using a suction cup method the ONH blood flow maintains almost constant until IOP reaches 40-55 mmHg. During isometric exercise the upper limit of autoregulation appears to be approximately 40% above the baseline ocular perfusion pressure. The mechanism behind ONH blood flow autoregulation is still unknown. The present experiments are designed to improve the investigators' knowledge of the physiology of regulatory mechanisms in ONH circulation, which may be helpful for a better understanding of blood flow abnormalities in glaucoma. This is of importance, because there is an increased evidence, that vascular dysregulation plays a role in the development of glaucomatous damage.

This study tests the assumption that the bioavailability of alprazolam from a new sublingual formulation is the same as that from sublingual formulation expected to be used commercially in Brazil.
The aims of the study are to evaluate the safety, tolerability and pharmacokinetics of AZD8075 in healthy male subjects at increasing doses when given for 14 days
Tissue hypoxia is the only accepted trigger for erythropoietin (EPO) production. However, in healthy subjects EPO concentrations have also increased after oxygen breathing. The aim of our study is to confirm these observations. Besides its main function in erythropoiesis, EPO has also shown tissue protective effects. The second goal of our study is to observe the cardioprotective effects of increased endogenous EPO, induced after normobaric oxygen breathing.
In a homeopathic drug proving a homeopathically prepared substance is administered to healthy volunteers in order to produce the symptoms specific to that substance and thereby reveal its inherent curative powers. During a homeopathic drug proving the goal is to provoke temporary symptoms (or "artificial illness") associated with the homeopathic medication. These symptoms are then arranged to form a symptom pattern or 'remedy picture' which is specific to that particular homeopathic substance and provides the basis for a better understanding of the possible effects of that homeopathic remedy in patients.
