IRON METABOLISM-IMPROVING AGENT
An acetic acid- and/or acetate salt-free iron metabolism-improving agent that contains citric acid and/or a citrate salt as electrolytes and also contains another/other electrolyte/electrolytes and glucose solely or in combination is provided. The iron metabolism-improving agent can be formulated into a dialysate and/or a substitution fluid. A method for improving internal iron metabolism and a blood purification method including hemodialysis and hemodiafiltration in a chronic renal failure patient employing the dialysate and/or the substitution fluid are further provided.
1 . An iron metabolism-improving agent, comprising at least one of citric acid and a citrate salt.
2 . The iron metabolism-improving agent according to claim 1 , wherein the agent comprises the at least one of citric acid and the citrate salt as an electrolyte.
3 . The iron metabolism-improving agent according to claim 1 , wherein:
the agent is free of acetic acid and acetate salts; and
the agent comprises the at least one of citric acid and the citrate salt as an electrolyte.
4 . The iron metabolism-improving agent according to claim 1 , wherein:
the agent comprises the at least one of citric acid and the citrate salt as an electrolyte;
the agent comprises at least one additional electrolyte; and
the agent comprises glucose.
5 . A dialysate, comprising the iron metabolism-improving agent according to claim 1 .
6 . A substitution fluid, comprising the iron metabolism-improving agent according to claim 1 .
7 . A method for improving iron metabolism in a chronic renal failure patient receiving blood purification therapy, comprising administering the iron metabolism-improving agent according to claim 1 to the patient.
8 . The method of claim 7 , wherein the blood purification therapy is selected from the group consisting of hemodialysis, hemofiltration and hemodiafiltration.
9 . A method for improving iron metabolism in a chronic renal failure patient receiving blood purification therapy, comprising administering the dialysate according to claim 5 to the patient.
10 . The method of claim 9 , wherein the blood purification therapy is selected from the group consisting of hemodialysis, hemofiltration and hemodiafiltration.
11 . A method for improving iron metabolism in a chronic renal failure patient receiving blood purification therapy, comprising administering the substitution fluid according to claim 6 to the patient.
12 . The method of claim 11 , wherein the blood purification therapy is selected from the group consisting of hemodialysis, hemofiltration and hemodiafiltration.
13 . A blood purification method, comprising performing at least one of hemodialysis and hemodiafiltration using the dialysate according to claim 5 .
14 . A blood purification method, comprising performing at least one of hemodiafiltration and hemofiltration using the substitution fluid according to claim 6 .
