357 Clinical Trials for Various Conditions
The objective of this study was to compare the individual pharmacokinetics of functional ingredients included in an oral rehydration solution (ORS) with or without the inclusion of active base ingredients (carbohydrate and electrolytes). The functional ingredients included in both the control and test solutions were Melatonin in conjunction with L-theanine (Arm 1), Caffeine in conjunction with L-theanine (Arm 2), and Vitamin C in conjunction with Zinc (Arm 3), across two study periods. The primary outcomes of this study included the relative pharmacokinetics of each functional ingredient. These included: maximum observed concentration (C max), time of maximum observed concentration (T max), cumulative Area Under the Curve (AUC) for each timepoint, (including AUC from the time of dosing to the time of last observation) and the concentration at each timepoint for the corresponding functional ingredients included in the specific study arm (i.e., melatonin, L-theanine, caffeine, vitamin C and zinc).
Fifteen female study participants will be enrolled in a randomized crossover study to measure fractional and total zinc and iron absorption from four common bean (Phaseolus vulgaris) varieties with varying phytate and polyphenolic contents. Phytate, the storage form of phosphorus in plants, and polyphenols, which contribute to the varied colors of common beans, are natural components of the beans and can reduce zinc and iron bioavailability from these foods.
To evaluate the absorption, metabolism, and excretion of \[14C\]-simufilam in healthy male subjects following a single oral administration of 100 mg of (approximately 100 µCi) \[14C\]-simufilam.
A Phase 1, Open-label Study of the absorption, metabolism, and excretion of a single oral dose of \[14C\]TVB-2640 healthy male subjects.
The objective of this project is to evaluate the postprandial serum and plasma vitamin and mineral levels in healthy adult men and women between 18 and 32 years of age, following a single intake of a multivitamin and mineral supplement processed in two different ways.
Topical timolol has been used primarily as eye drops to treat glaucoma for many years. Recent clinical experience has broadened its off-label use for a number of skin conditions, including slow-healing wounds. While there have been extensive safety studies performed on timolol administration to treat the eye, to date, no studies have documented absorption of timolol after applied on chronic wounds. Thus, the purpose of this study is to determine the blood levels of timolol in patients after topical administration to a chronic wound, and compare these levels with those of patients after administration of the same drug formulation on the eye for the indication of glaucoma.
The purpose of this study is to determine the absorption, metabolism, and excretion of \[14C\]-TBPM-PI-HBr and to characterize and determine the metabolites present in plasma, urine, and where possible, feces in healthy male subjects following a single oral administration.
This study is intended to evaluate the comparative effects of direct analysis of serum samples versus pre-treatment with enzymatic hydrolysis in split samples obtained from dosing with a highly absorbed curcumin emulsion product that is commercially available as BIOCURC.
The objective of this project is to determine the extent to which eating black pepper together with vegetables increase the absorption of carotenoids (a class of important nutrients) in the vegetables such as beta-carotene.
GC4419 is being studied to treat and prevent oral mucositis (painful inflammation) in cancer patients who receive radiation and chemotherapy. In this study, GC4419 will be mixed with a small amount of radioactive material in order to find out how much study drug is in the blood and to see how the drug is processed and eliminated from the body. The safety and how subjects tolerate the study drug will also be studied.
The goal of the research study is to measure and compare the absorption of equivalent amounts of beta-cryptoxanthin and Iycopene provided in citrus fruit. The investigators want to determine whether adults absorb beta-cryptoxanthin to a greater extent than lycopene, when both are supplied in comparable citrus fruits.
This is an open-label, single-dose, randomized crossover study of single oral 10-mg tablet doses administered either after an overnight fast or in combination with a standard high-fat meal in healthy subjects.
The aim of the present study is to validate a new method in healthy volunteers and those diagnosed with COPD and CHF that is able to measure protein digestion and absorption simultaneously. This method is used to quantify digestion and absorption in patients who are suspect of impaired digestion and absorption resulting in loss of nutrients.Findings may be used to develop treatment strategies to improve protein digestion and absorption in these patient groups.
We propose to study both stool and urine energy loss in 24 individuals on two experimental diets (50% increased and 50% reduced nutrient load relative to body size) in a random cross-over design. Following this over/underfeeding, volunteers will also be randomly assigned to a placebo versus oral antibiotic medication arm. This study will extend our previous findings by investigating whether 1) nutrient absorption changes upon similar increases/decreases in relative nutrient load and 2) whether manipulation of gut microbial communities with antibiotics alters nutrient absorption and 3) how these changes may affect glucose tolerance and fat storage.
The investigators predict that a powder pill form of vitamin D will be more effectively absorbed than an oil form of vitamin D in people diagnosed with Cystic Fibrosis.
The purpose of this study is to evaluate whether taking thyroid hormone medication with beverages other than water, decreases absorption of the medication by the intestine. Specifically we are interested in whether coffee, coffee with milk, or black tea affects how thyroid medication is absorbed by the body. Previous studies have suggested that taking thyroid hormone with coffee may interfere with the ability to absorb thyroid medicine. Given that many patients take their thyroid medicine with beverages other than water, and specifically with coffee or tea, understanding whether and how much coffee or tea may decrease thyroid hormone absorption is important for clinical practice. This study will help determine the safest and most effective way for adults to take their thyroid medication and will guide medical practitioners in how to counsel their patients when they prescribe thyroid hormone.
The purpose of this study is to determine whether or not the intake of dietary procyanidins (oligomers of flavanols) contribute to the systemic presence of flavanols in healthy humans.
The purpose of the study is to evaluate the absorption, distribution, metabolism and excretion of AZD1656 after administration of a single oral dose of 14C-labelled AZD1656 solution in male Type 2 Diabetes Mellitus patients.
This study was to determine the ADME and metabolites of Proellex following a single oral dose of 25 mg.
Iron deficiency is a common health problem worldwide. Ferrous fumarate (a form of iron) is often added to foods in an effort to prevent iron deficiency. Vitamin C can improve the amount of iron that the body absorbs, therefore it is often added to foods too. However, we don't know if vitamin C really increases the absorption of iron from ferrous fumarate. This study will measure the iron absorption in children from a meal containing some ferrous fumarate with and without vitamin C. The study will include 4 visits to the Children's Nutrition Research Center in Houston, TX.
This is a phase one study investigating the absorption, distribution, metabolism and excretion of GSK221149A in six healthy women of non-child bearing potential.
This study evaluates the subjective effects of injection administration of NR on healthy adult populations.
