Assessment: Tools
FRAX
QFracture
Management: Antiresorptive drugs
Oral Bisphosphonates - 1st line
IV Bisphosphonates e.g. Zoledronic acid - can be 1st line after hip fracture
Bisphosphonates: Alendronic Acid
Dosing, how to take it, S/E
Once daily or once weekly dosing
Take with water while sitting straight or standing in an empty stomach at least 30mins before breakfast
S/E - Oesophageal reactions, dysphagia, new or worseing heartburn, pain on swallowing
Bisphosphonates: Risedronate sodium
Dosing, how to take it
Once daily or Once weekly dosing
Take with water while sitting straight or standing in an empty stomach at least 30mins before breakfast
Bisphosphonates: S/E
Osteonecrosis of the jaw and auditory canal - more likely in IV bisphosphonates
Atypical femoral fractures
Bisphosphonates: Treatment holiday
Oral - review after 5 years
IV - review after 3 years (zoledronic acid)
Longer treatment of 10 yrs - consider in over 70yrs
Denosumab
Route, monitoring, S/E
SC
Monitor - calcium (causes hypocalcaemia)
Alternative for oral bisphosphonates due to swallowing difficulties or contraindications
S/E - osteonecrosis of the jaw, atypical femoral fractures
Selective Oestrogen-Receptor Modulator (SERM): Raloxifene
Given if oral bisphosphonates are not suitable
Strontium Ranelate
Why it is given, dosing, counselling
