Strontium ranelate normalizes bone mineral density in osteopenic patients
Abstract
AIMS: To assess the capacity of strontium ranelate to restore normal bone mineral density (WHO definition: T-score >or=-1) in post-menopausal osteopenic women (T-score between -1 and -2.5) at baseline.
METHODS: Post-hoc analysis from SOTI and TROPOS studies of 1428 patients randomly assigned to receive either 2 g of strontium ranelate a day or placebo for three years. Bone mineral density was measured at baseline and each year for three years. Results were analyzed on an intention-to-treat basis.
RESULTS: At lumbar spine, after one, two and three years of treatment with strontium ranelate, 26.4, 42.1 and 58.2% respectively of osteopenic patients normalized their bone mineral density, compared with 6.6, 8.9 and 11.9% in the placebo group (all p<0.001). At total hip, the percentage of patients normalizing their bone mineral density was 5.4, 10.0 and 19.6% in the strontium ranelate group and 1.8, 1.4 and 1.6% in the placebo one (all p<0.001).
CONCLUSION: Strontium ranelate is able to normalize bone mineral density in a significant proportion of osteopenic patients after one, two and three years of treatment. The clinical relevance of these results should be confirmed by direct demonstration of the anti-fracture efficacy of strontium ranelate in osteopenic patients.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 1,428 participants or records.
