Bisphosphonates, the most widely prescribed drugs in this field, have been linked to a 12-month persistence lower than 40%.

Low compliance results in lesser increase in bone mineral density and decreased anti-fracture efficacy. New medications, currently developed for the management of osteoporosis, will be user-friendly, allowing to an improvement of compliance and persistence.
