title: Clinical appraisal of vinpocetine for the removal of intractable tumoral calcinosis in haemodialysis patients with renal failure.
abstract: Previous studies have shown that vinpocetine [14-ethoxycarbonyl-(3 alpha, 16 alpha-ethyl)-14,15-eburnamenine] scavenges minerals and/or metals in the soft tissues of rabbits with artificially induced arteriosclerosis. The present study was carried out to determine whether or not vinpocetine would bring about the removal of intractable tumoral calcinosis in haemodialysis patients with renal failure. After administration of 15 mg/day vinpocetine for 3-12 months in haemodialysis patients with X-ray evidence of tumoral calcinosis, calcinosis was completely eliminated in all eight cases. Serum alkaline phosphatase and bone osteocalcin concentrations tended to decrease after treatment with vinpocetine compared with before treatment. Vinpocetine thus appears to be an effective scavenger of tumoral calcinosis in haemodialysis patients with renal failure without any side-effects during treatment.
