Bioavailability of butorphanol after intranasal administration to horses
(Trakia University, 2020-12)
The aim of the present study was to describe butorphanol pharmacokinetics and bioavailability following intranasal administration to horses. Six adult horses received 0.05 mg/kg butorphanol, in a randomised crossover design, ...
One-month of calcium supplementation does not affect iron bioavailability: A randomized controlled trial
(2014)
Objectives: Calcium (ca) and iron (Fe) are essential minerals for normal growth and development. Although previous studies have shown that Ca inhibits acute Fe absorption, there is no evidence of the possible long- or ...
Efavirenz-loaded polymeric micelles for pediatric anti-HIV pharmacotherapy with significantly higher oral bioavailability
(Future Medicine, 2010-01)
Children constitute the most challenging population in anti-HIV/AIDS pharmacotherapy. Efavirenz (EFV; aqueous solubility 4 µg/ml, bioavailability 40–45%) is a first-line agent in the pediatric therapeutic cocktail. The ...
New insights about iron bioavailability inhibition by zinc
(ELSEVIER SCIENCE INC, 2007-04)
Objective: We measured the effects of lower and higher doses of zinc (Zn) given as an aqueous solution on the bioavailability of iron (Fe). Methods: Fourteen healthy subjects received a solution with 0.5 mg of elemental ...
Released fraction of polychlorinated biphenyls from soil–biosolid system using a leaching procedure and its comparison with bioavailable fraction determined by wheat plant uptake
(Springer, 2017)
The bioavailability of polychlorinated biphenyls
(PCBs) in soils amended with biosolids was estimated using
an aqueous leaching process of the compounds combined with
rotating disk sorptive extraction (RDSE), and compared ...
In vitro evaluation of Cu and Fe bioavailability in cashew nuts by off-line coupled SEC-UV and SIMAAS
(ELSEVIER SCIENCE BV, 2010)
In this work Cu and Fe bioavailability in cashew nuts was evaluated using in vitro method. Extractions with simulated gastric and intestinal fluids and dialysis procedures were applied for this purpose. The proteins ...
Cyclodextrin-modified nanomaterials for drug delivery: classification and advances in controlled release and bioavailability
(MDPI, 2021)
In drug delivery, one widely used way of overcoming the biopharmaceutical problems
present in several active pharmaceutical ingredients, such as poor aqueous solubility, early instability,
and low bioavailability, is the ...
