restarting bisphosphonates after drug holiday zenegra

Bisphosphonates, the most commonly prescribed class of agent for the treatment of osteoporosis, have proven efficacy for prevention and treatment of bone loss and fractures due to aging, estrogen deficiency, and glucocorticoid use. The challenge is to be informative, assess your patients' risk of fracture on a regular basis, and do not overlook patients who have had a fracture.2. In studies of zoledronic acid use up to six years and alendronate use up to 10 years, continued treatment showed a reduction in both bone loss and vertebral fractures. FRAX tool can be found here . All bisphosphonate therapies carry warnings or contraindications. The benefits of risedronate appear to be of shorter duration after discontinuation until BMD and bone turnover markers returned to baseline. The American Association of Clinical Endocrinologists (AACE) guideline suggests a drug holiday after 4 to 5 years of BP treatment in patients at moderate risk of fractures and after 10 years for high‐risk patients, but the terms high and moderate risk were not defined. In addition, the management of osteoporosis should include multiple fronts. <> Black DM, Reid IR, Cauley JA, et al. The utility of basing treatment decisions on monitoring BMD and bone turnover markers has not been evaluated in prospective studies. Although bisphosphonates are often considered as a class, the sustained effects of the drugs differ and need to be taken into account for individualizing clinical decisions.

The BMD and bone marker changes showed some residual effect for at least five years after subjects had ended a five-year course of therapy.Continuing alendronate treatment for five years reduced the risk of clinical vertebral fracture. The authors recommend that almost all patients who receive zoledronic acid can probably stop and expect benefit for up to three additional years. The drug holiday can be continued based on the estimated resolution of effect of the drug or significant loss of BMD or if the patient has a fracture.If fracture risk is high after three to five years, continue bisphosphonate treatment for up to 10 years or change therapy to a nonbisphosphonate. 6. This results in the observed gradual upward trend in bone turnover rather than a rapid increase. 3 0 obj ,�b��3��W��ʊ��&�Ȃ9�%N�6U�L%J��˗��=�}&�\O0E�-��`��T-�!Gx�mI�-r�$[cX�E�R}ɔiU��H The benefits of lowering the incidence of typical osteoporotic fractures outweigh the risks of serious adverse events. Schwartz AV, Bauer DC, Cummings SR, et al. If a drug holiday is advised, reassessment of risk should occur sooner for drugs with lower skeletal affinity. 7. Only those subjects in the active drug arm were offered to continue. %�� If your high-risk patient has been on bisphosphonates for long term, consider a drug holiday of one to three years, or until there is significant loss of BMD or the patient has a fracture, whichever comes first. However, the extension trials had smaller numbers of subjects and were not powered for fractures as a primary endpoint. From the outset, let me point out there is little evidence to guide us as clinicians. Nelson Watts, MD, an internationally recognized endocrinologist, refers to this as a "data-free zone." If the patient has not achieved a bone density at the femoral neck of -2.5 or higher after five years, she may benefit from an additional five years of therapy. endobj The gray zone is for women in the -2 to -2.5 range of BMD at the femoral neck.Bone biologists have estimated that about 75 mg of alendronate is retained in the skeleton after 10 years of therapy with 10 mg a day or 70 mg a week dosing.3 Upon stopping treatment, the release of alendronate from remodeling is estimated to be approximately the same as taking a daily dose of 2.5 mg. Eastell R, Hannon RA, Wenderoth D, et al. 4 0 obj Consider sequential therapy with other nonbisphosphonate agents as well. 3. This correlated with a slow decline in BMD after stopping alendronate. (“drug holiday”) of 2 years for oral bisphosphonates. Black DM, Reid IR, Boonen S, et al. The effect of 6 versus 9 years of zoledronic acid treatment in osteoporosis: a randomized second extension to the HORIZON-Pivotal Fracture Trial (PFT) [published online December 26, 2014]. Prevention of falls is tantamount since more than 90% of hip fractures in older adults are the result of a fall.Although the risk of AFF and ONJ is higher with bisphosphonate use, it is extremely small. The risk of vertebral, hip, and other nonvertebral fractures was reduced in women with osteoporosis. The mean serum levels of bone turnover markers measured remained within the premenopausal reference range in both groups.
