FOSRENOL effectively controls hyperphosphatemia, a leading cause of renal osteodystrophy and bone pain in ESRD patients. Long-term use maintains bone health status without worsening bone status, unlike aluminum-based phosphate binders.
Researchers studying lanthanum barium copper oxygen (LBCO) found that adding barium creates electron holes, which are necessary for superconductivity. The study suggests that fluid stripes may be essential for high-temperature superconductivity in these materials.
New global trials build on earlier phase III studies demonstrating FOSRENOL's efficacy in treating hyperphosphataemia. The new trials aim to confirm safety and efficacy of the phosphate binder, which has shown lower incidence of hypercalcaemia compared to calcium-based binders.
FOSRENOL, a lanthanum carbonate-based treatment, has been approved for reducing phosphate risk in dialysis patients with end-stage renal failure. The treatment has shown effectiveness and well-tolerability in studies, improving bone disease outcomes.
A 11-week study showed lanthanum carbonate significantly reduced serum phosphorus levels in hemodialysis patients, meeting the new K/DOQI guidelines. Sixty percent of patients achieved target levels, with lower calcium x phosphate product.
Phosphate reduction is achieved within a week of treatment with lanthanum carbonate, a new phosphate binder. This effective treatment reduces serum calcium levels and improves cardiovascular health in end-stage renal disease (ESRD) patients.
Long-term data show effective control of serum phosphate levels, with 71.7% achieving target levels after one year and 68.9% after three years. Low incidence of hypercalcaemia is also maintained throughout the study period.
A 52-week extension trial found that lanthanum carbonate successfully maintained lowered phosphate levels in patients with end-stage kidney disease.
