How effective are Evrenzo tablets 50 mg from Japan for renal anemia (roxadustat)?
Evrenzo tablets contain Roxadustat, a new inhibitor of HIF (hypoxia inducible factor), transcription factor that responds to decreases in available oxygen in the cellular environment. It works by activating HIF pathways and degrading HIF, by this, increasing endogenous production of erythropoietin, a glycoprotein cytokine secreted mainly by the kidney in response to cellular hypoxia. As the result, Evrenzo tablets stimulate red blood cell production (erythropoiesis) and production of hemoglobin, increase the increase the number of red blood cells and improve the symptoms of renal anemia.
Who should take Evrenzo tablets 50 mg from Japan?
At first, roxadustat was approved for using in patients undergoing dialysis, but since 2020 it was also approved in Japan for patients not receiving dialysis. Multiple studies showed that roxadustat leads to a numerically greater mean change in hemoglobin level, increases the transferrin level, decreases total cholesterol and low-density lipoprotein cholesterol level (T. Akizawa, M. Ueno et al. “Oral roxadustat three times weekly in ESA-naive and ESA-converted patients with anemia of chronic kidney disease on hemodialysis”. Therapeutic apheresis and dialysis, 2020, December, 24(6): 628-641). That’s why Evrenzo tablets are effective for the treatment of anemia attributable to renal diseases.
