UNLABELLED Lanthanum carbonate is an efficacious noncalcium, nonresin phosphate-binder that is being increasingly used in chronic kidney disease stage 5 (CKD-5) dialysis patients. Available evidence has indicated that QT interval changes correlate with mortality in healthy subjects and in dialysis patients. Experimental studies have suggested the possibility that lanthanum carbonate may produce...

This study was undertaken to evaluate directly the relationship between evolution of irreversible myocardial injury induced by hypoxia in an isolated papillary muscle preparation and the development of pathophysiological alterations related to severely impaired membrane function. An ionic lanthanum probe technique was employed as a cytochemical marker to monitor the progression of cellular inju...

an efficient one pot multi component synthesis of 1, 4-polyhydroquinoline derivatives through unsymmetrical hantzsch reaction using lanthanum chloride heptahydrate (lacl3.7h2o) from an aromatic aldehyde, ethyl acetoacetate, dimedone and ammonium acetate as a nitrogen precursor in ethanol at room temperature is described. in the present work we report lanthanum chloride heptahydrate remarkably n...

Stable hairy lanthanum hydroxide nanoparticles were synthesized in water by performing hydrolysis and condensation reactions of lanthanum cations in the presence of double hydrophilic polyacrylic acid-b-polyacrylamide block copolymers (PAA-b-PAM). In the first step, the addition of asymmetric PAA-b-PAM copolymers (Mw,PAA o Mw,PAM) to lanthanum salt solutions, both at pH = 5.5, induces the forma...

Complexes of lanthanum(III) with bis-coumarins: 3,3'-benzylidene-bis(4-hydroxy-2H-1-benzopyran-2-one) (H(2)L1) and bis(4-hydroxy-2-oxo-2H-chromen-3-yl)-(1H-pyrazol-3-yl)-methane (H(2)L2) were synthesized by reaction of lanthanum(III) salt and the ligands, in amounts equal to metal : ligand molar ratio of 1 : 2. The complexes were prepared by adding an aqueous solution of lanthanum(III) salt to ...

To investigate the effects of lanthanum chloride on binding of LPS to monocyte and CD 14 expression upregulation induced by LPS, human monocytes were analyzed by flow cytometry (FCM). The results indicated that lanthanum chloride could decrease the binding rate of LPS with monocyte significantly. LPS upregulated the expression of CD 14 on monocyte in a dose dependant manner, however, lanthanum ...

BACKGROUND AND OBJECTIVES Phosphate binders such as calcium salts or sevelamer, a cationic polymer, can markedly reduce absorption of oral ciprofloxacin. This randomized, open-label, two-way, crossover study examined the influence of the cation lanthanum on systemic ciprofloxacin exposure after oral administration. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Twelve patients randomly receive...

BACKGROUND The majority of patients with end-stage renal disease on dialysis are hyperphosphataemic. Lanthanum carbonate has been shown to be a highly effective phosphate binder in pre-clinical studies. A 4-week, open-label, dose-titration trial was conducted to assess the ability of lanthanum carbonate to control phosphate levels in patients with chronic renal failure. METHODS This prelimina...

Elevated serum phosphate levels as a consequence of chronic kidney disease (CKD) contribute to the increased cardiovascular risk observed in dialysis patients. Protein restriction and dialysis fail to adequately prevent hyperphosphatemia, and in general treatment with oral phosphate binding agents is necessary in patients with advanced CKD. Phosphate plays a pivotal role in the development of v...

Correction of metabolic acidosis after conversion from sevelamer hydrochloride to lanthanum carbonate Sir, We recently introduced lanthanum carbonate as an alternative phosphate binder to sevelamer hydrochloride in patients with elevated serum calcium. Lanthanum carbonate has a higher affinity for phosphate than sevelamer HCl, so fewer lanthanum carbonate tablets are required to achieve the sam...
