Strontium ranelate effectively reduces vertebral and non-vertebral fractures in postmenopausal osteoporosis, also increasing bone mineral density. While diarrhea is a possible side effect, serious adverse events were not significantly increased.
Area of Science:
- Osteoporosis Treatment and Prevention
- Pharmacological Interventions for Bone Health
Background:
- Osteoporosis poses a significant health risk to postmenopausal women.
- Strontium ranelate is a novel therapeutic agent for osteoporosis requiring efficacy and safety evaluation.
Purpose of the Study:
- To assess the efficacy and safety of strontium ranelate in treating and preventing postmenopausal osteoporosis.
- Evaluate strontium ranelate's impact on fracture incidence, bone mineral density (BMD), and quality of life.
Main Methods:
- Systematic review and meta-analysis of randomized controlled trials (RCTs) with at least one year duration.
- Included studies compared strontium ranelate versus placebo in postmenopausal women, focusing on fracture data, BMD, and safety outcomes.
- Data extraction and quality assessment were performed independently by two reviewers.
Main Results:
- Strontium ranelate (2 g daily) demonstrated a 37% reduction in vertebral fractures and a 14% reduction in non-vertebral fractures over three years.
- Significant increases in bone mineral density (BMD) were observed at all measured sites in both treatment and prevention populations.
- Diarrhea was a noted side effect, but adverse events did not lead to increased treatment discontinuation or serious adverse events.
Conclusions:
- Silver level evidence supports strontium ranelate's efficacy in reducing fractures and increasing BMD in postmenopausal osteoporotic women.
- While diarrhea is a potential adverse event, strontium ranelate (2 g daily) appears safe regarding serious side effects and treatment withdrawal.
- Further investigation into potential vascular and neurological side effects associated with strontium ranelate is warranted.

Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...
