Abstract

Zusammenfassung

Kalzium-Sensing-Rezeptor-Antagonisten stellen eine in präklinischer Erprobung befindliche Option zur anabolen therapeutischen Intervention in Fällen von schwerer Osteoporose mit hoher Frakturgefährdung dar. Bisher wurden im Tierversuch vielversprechende Ergebnisse erzielt, die jedoch in klinischen Studien an Menschen aufgrund der komplexen pharmakokinetischen Anforderungen an die Substanz nicht bestätigt werden konnten. In naher Zukunft werden die Ergebnisse zweier klinischer Studien an postmenopausalen, osteoporotischen Patientinnen für das Jahr 2012 erwartet.

Summary

Calcium-sensing-receptor-antagonists belong to the class of osteo-anabolic drugs offering another therapeutic option for the pharmacologic treatment of osteoporosis with increased risk of fracture. Preclinical studies revealed encouraging results, while some human trials have failed to confirm the expectations most likely due to the challenging pharmacokinetic profile required for these drugs when given orally. In 2012 the results of two clinical studies in postmenopausal women are expected to provide more data on the potential clinical value of this new class of osteo-anabolic drugs.
