A new once-monthly tablet formulation containing risedronate sodium 150 mg (Actonel Once-a-month) was listed on the PBS on 1 July 2009. The authority-required (streamlined) listing is for treatment as the sole PBS-subsidised anti-resorptive agent for osteoporosis in people1:

  • with a fracture due to minimal trauma
  • aged 70 years or older with a bone mineral density (BMD) T-score ≤ –3.0
  • on long-term high-dose corticosteroid therapy (at least 7.5 mg/day of prednisolone or equivalent for ≥ 3 months) with a BMD T-score ≤ –1.5.

These restrictions are in line with other currently listed risedronate products (Actonel, Actonel Once-a-week, Actonel Combi, Actonel Combi D).


Update on PBS-listed anti-resorptive drugs and their restrictions
