Introduction: Osteoporosis is a chronic, skeletal disorder characterized by compromised bone strength and increased risk of fractures, affecting up to 50% of postmenopausal women worldwide. Over the past 2 decades there have been consistent developments in the pharmacotherapy of osteoporosis with the availability of potent inhibitors of bone resorption (bisphosphonates, and denosumab) or stimulators of bone formation (PTH analogs) with substantial improvements over calcitonin or estrogen replacement. Areas covered: In this review we summarize the effects of existing treatment options for postmenopausal osteoporosis along with the unmet clinical needs and we discuss about the potential benefits of new compounds under development. Expert opinion: Despite the recent progresses, there are still limitations and unmeet needs with all the available drugs, mainly concerning treatment adherence, efficacy on the prevention of nonvertebral fractures and the long-term adverse events of antiresorptive regimens. Moreover, PTH analogs are the only available compounds able to stimulate bone formation, but with a restricted anabolic window of no more than 2 years. Of interest, the more recent advances in bone biology identified new targets for the development of drugs with a more potent and selective activity on either osteoclasts or osteoblasts, thus making possible to uncouple bone formation from bone resorption.
