The FDA has approved Actonel withCalcium (risedronate sodium with calciumcarbonate tablets, USP) for the treatmentand prevention of osteoporosis inpostmenopausal women. Although Actonelalone is currently available, the additionof calcium tablets makes this thefirst prescription osteoporosis medicationto include calcium supplementation,a crucial part of osteoporosis pharmacotherapy.1

The formulation of Actonel withCalcium was prompted by the SurgeonGeneral's 2004 Report on Bone Healthand Osteoporosis, which found that theaverage adult consumes about 700 mgof elemental calcium daily—significantlyless than the recommended dailyallowance of 1200 mg for women overage 50. Actonel with Calcium may providethe additional 500 mg of elementalcalcium that may be missing from manyadults' diets.2

In addition, the report summons allAmericans—both the public and thehealth care community—to take the initiativein preventing and treating osteoporosis.Health care workers are encouragedto watch for red flags, such as multiplefractures in a patient under age 50or health conditions that can lead tobone loss. Currently, 10 million Americansover age 50 have osteoporosis, and34 million others are at risk for developingthe condition.3

Actonel with Calcium consists of aonce-weekly 35-mg risedronate tabletand six 1250-mg calcium carbonatetablets (500 mg of elemental calcium) tobe taken on the remaining days of theweek. It is packaged as a 28-day therapyand aims to increase patient compliancewith calcium supplementation.1 Actonelwith Calcium is marketed by the Alliancefor Better Bone Health, a joint effortbetween Procter & Gamble Pharmaceuticalsand Aventis Pharmaceuticals.2
