According to a recent study, although the drug zoledronic acid slows bone loss in osteoporosis patients, it also boosts levels of a biomarker that stops bone formation.
The study got accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
Osteoporosis weakens bones and increases the risk patients will suffer fractures. The findings suggest combination therapy may be a more effective approach to battling this common condition.
The prospective intervention study followed the treatment of 40 postmenopausal women at an ambulatory care center. Half of the women received zoledronic acid, and half received a placebo. Levels of sclerostin - a biomarker that inhibits bone formation - increased among the participants who were treated with zoledronic acid.
"The data points to an opportunity to increase bone mass by combining zoledronic acid with a drug that suppresses the resulting sclerostin's effect," Catalano said. "An innovative combination therapy using zoledronic acid and selective antibodies to block the sclerostin could simultaneously stop bone loss and encourage new bone formation. This is an important avenue for researchers to explore as they develop new osteoporosis treatments."
