In this study, a significant effect of sodium citrate increasing fenofibrate dissolution has been demonstrated. This effect was dependent on the polymer: drug mixing weight ratio, the sodium citrate type and the method used to disperse the drug with in the polymer. The greater the sodium citrate content the higher the drug dissolution was, up to a maximum corresponding to a polymer: drug ratio ...
We describe herein the significance of a sodium citrate and tannic acid mixture in the synthesis of spherical silver nanoparticles (AgNPs). Monodisperse AgNPs were synthesized via reduction of silver nitrate using a mixture of two chemical agents: sodium citrate and tannic acid. The shape, size and size distribution of silver particles were determined by UV-Vis spectroscopy, dynamic light scatt...
OBJECTIVE Citrate, potassium, and calcium levels in Viburnum opulus (V. opulus) and lemon juice were compared to evaluate the usability of V. opulus in mild to moderate level hypocitraturic stone disease. MATERIALS AND METHODS V. opulus and lemon fruits were squeezed in a blender and 10 samples of each of 100 ml were prepared. Citrate, calcium, sodium, potassium, magnesium, and pH levels in t...
Citrate is a key regulatory metabolic intermediate as it facilitates the integration of the glycolysis and lipid synthesis pathways. Inhibition of hepatic extracellular citrate uptake, by blocking the sodium-coupled citrate transporter (NaCT or SLC13A5), has been suggested as a potential therapeutic approach to treat metabolic disorders. NaCT transports citrate from the blood into the cell coup...
The crystal structure of sodium potassium hydrogen citrate has been solved and refined using laboratory X-ray powder diffraction data, and optimized using density functional theory techniques. The Na(+) cation is six-coordinate, with a bond-valence sum of 1.17. The K(+) cation is also six-coordinate, with a bond-valence sum of 1.08. The distorted [NaO6] octahedra share edges, forming chains alo...
The gene of the sodium-dependent citrate transport system from Klebsiella pneumoniae (citS) is located on plasmid pES3 (Schwarz, E., and Oesterhelt, D. (1985) EMBO J. 4, 1599-1603) and encodes a 446-amino acid protein. Transport of citrate via this citrate transport protein (CitS) is dependent on the presence of sodium ions and is inhibited by magnesium ions. The delta pH (pH gradient across th...
Fentanyl Citrate Injection, USP is a potent o p i o i d ag o nis t . Each milliliter of solution contains fentanyl citrate equivalent to 50 mcg of fentanyl base, adjusted to pH 4.0 to 7.5 with sodium hydroxide. Fentanyl citrate is chemically identified as N-(1-phenethyl-4-piperidyl) propionanilide citrate (1:1) with a molecular weight of 528.60. The empirical formula is C22H28N2O • CH8O7. The s...
