A straightforward, sensitive, and quick spectrophotometric approach was created validated for the detection of Ciprofloxacin hydrochloride, Moxifloxacin Roxithromycin hydrochloride in pure form. These techniques were based upon fact that these antibiotics produced dark yellow ion pairs when combined with bromophenol blue. The binary complex universal buffer solution optimum pH values demonstrat...

OBJECTIVES AND BACKGROUND The objective of this study was to investigate the image quality-improving and heart rate-lowering effects of landiolol hydrochloride (a short-acting β1-adrenergic receptor blocker) on coronary computed tomography angiography (CCTA). During CCTA, β-adrenergic receptor blockers have been commonly used to lower heart rate and improve image quality. METHODS A total of 2...

DESCRIPTION Aloxi (palonosetron hydrochloride) is an antiemetic and antinauseant agent. It is a selective serotonin subtype 3 (5-HT3) receptor antagonist with a strong binding affinity for this receptor. Chemically, palonosetron hydrochloride is: (3aS)-2-[(S)-1-Azabicyclo [2.2.2]oct-3-yl]-2,3,3a,4,5,6-hexahydro-1oxo-1Hbenz[de]isoquinoline hydrochloride. The empirical formula is C19H24N2O.HCl, w...

Prior studies of the viscosity of the subunit proteoglycan obtained by dissociative extraction of bovine nasal septum cartilage suggested that the proteoglycan subunit molecule behaves as a rigid rod in aqueous solution over the range of 0.5 to 4.0 M guanidine hydrochloride. A more direct view of dimension and shape can be obtained from light-scattering and viscosity of bovine nasal cartilage p...

The aim of the investigation was research N-deacetyllappaconitine hydrochloride antiarrhythmic properties. It found that studied substance effective on cardiac arrhythmias model caused by aconitine hydrochloride, but does not act models calciume chlorideinduced and reperfusion ventricular fibrillation. compound is less toxic than comparison drug lappaconitine hydrobromide acts in lower doses ar...

A method utilizing bovine serum albumin (BSA) as buffer additive for chiral separation by means of capillary electrophoresis is described. Parameters that affect chiral separation, such as buffer pH, buffer concentration, BSA concentration, and organic modifier, are investigated. Baseline resolution of ephedrine-pseudoephedrine and norephedrine-norpseudoephedrine isomers are achieved in an unco...
