Knoglemineraltæthed (BMD) I et to- års, dobbeltblindt multicenterstudie (BM 16549) var Bonviva 150 mg én gang om måneden mindst ligeså effektivt som ibandronsyre 2, 5 mg daglig til at øge BMD hos postmenopausale kvinder med osteoporose (lumbal BMD T score under - 2, 5 SD ved baseline).
Bone mineral density (BMD) Bonviva 150 mg once monthly was shown to be at least as effective as ibandronic acid 2.5 mg daily at increasing BMD in a two year, double-blind, multicentre study (BM 16549) of postmenopausal women with osteoporosis (lumbar spine BMD T score below -2.5 SD at baseline).
