Effect of nandrolone decanoate and 1- α-hydroxy-calciferol on patients with vertebral osteoporotic collapse. A double-blind clinical trial

Abstract

Eighty-eight postmenopausal women with at least one vertebral collapse were randomly assigned to two groups of 44 patients each. All patients were treated for a period of 12 months with 50 mg of nandrolone decanoate every 3 weeks or 1 μg of 1- α-hydroxy-calciferol daily. Both groups received an identical placebo of the inactive drug. Pain intensity was significantly decreased in the nandrolone group and mobility was improved. Patients treated with vitamin D metabolite had also a beneficial but less obvious clinical result. Bone mineral measurements showed an increase of 5% in the nandrolone decanoate group, but a 2.5% decrease in the vitamin D metabolite group. Biochemical results showed a significant hypercalciuric effect of vitamin D metabolite, while nandrolone decanoate caused a reduction in calcium/creatinine excretion. No difference in serum lipids was found during the annual treatment in both groups. It is concluded that nandrolone decanoate has a beneficial effect in clinical symptoms, bone mineral density and biochemical parameters in patients with established osteoporotic vertebral fractures.
