Alendronate Now Approved for Weekly Dosing

KEY POINT

Based on the pharmacokinetics of alendronate (Fosamax—Merck) and the physiology of the bone-remodeling process, once-weekly administration of this bisphosphonate is just as effective as daily regimens. In fact, once-weekly dosing exposes the GI tract to less irritation than do daily doses, and patients generally prefer to take the 70 mg tablet once weekly.
