Avosentan reduces proteinuria but causes critical side effects

Despite assertive treatments, people with kidney disease mostly experience proteinuria, or extreme loss of protein in the urine, that increases kidney damage. A key cause in the growth of proteinuria is endothelin, that by constricting red red blood vessels and raising red red blood pressure, causes the kidneyfiltering duty to deteriorate. Researchers think that restraint the endothelin peptide could be a earnest new diagnosis plan for patients who rise proteinuria. Endothelin antagonists such as verbal avosentan are already accessible and are prescribed for patients with cardiovascular conditions.

Johannes Mann, MD (Schwabing General Hospital and KfH Kidney Centre, in Munchen, Germany) and his colleagues carefully thought about the goods of avosentan on proteinuria and kidney duty in patients with sort 2 diabetes and kidney disease by a multicenter, multinational, double-blind, tranquil trial. The Avosentan ASCEND investigate enrolled 1392 patients already being treated with colour for kidney disease and randomized them to embrace avosentan twenty-five mg, avosentan 50 mg, or placebo.

While avosentan at possibly sip lowered patients" urinary protein excretion by 40%-50% (compared with less than 10% in patients receiving placebo), people receiving the drug experienced a high occurrence of serious, infrequently life-threatening side effects. These enclosed complications of liquid overkill such as pulmonary edema, as well as congestive heart failure. In addition, there were some-more deaths in the groups receiving avosentan (21 and 17) than in the organisation receiving remedy (12).

Dr. Mann remarkable that the commentary from the ASCEND hearing prominence the risks and intensity benefits of endothelin antagonists in kidney disease patients with proteinuria and will assistance investigators pattern destiny studies to exam the drugs" potential. Specifically, reduce doses of avosentan might beget some-more certain results.
