RT Journal Article SR Electronic T1 Role of alendronate and risedronate in preventing and treating osteoporosis JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 945 OP 951 VO 68 IS 11 A1 Margaret L. Peters A1 Mandy Leonard A1 Angelo A. Licata YR 2001 UL http://www.ccjm.org/content/68/11/945.abstract AB Alendronate and risedronate, the two oral bisphosphonates approved in the United States for preventing and treating osteoporosis, have never been compared in direct head-to-head trials, but they appear to have similar pharmacokinetics, drug interactions, adverse effect profiles, and efficacy. Alendronate, however, can be given as a once-weekly dose, whereas risedronate is not yet available in this dosage form. On the other hand, alendronate is not approved for preventing glucocorticoid-induced osteoporosis, whereas risedronate carries this indication.
