Older treatments like mithramycin and calcitonin have recently been replaced with newer management strategies, mostly involving bisphosphonates. Emerging therapeutic approaches include monoclonal antibodies to parathyroid hormone related peptide (PTH-rP), inhibition of RANK ligand through the use of a soluble form of its receptor osteoprotegerin, analogues of vitamin D and selective inhibition of the Ras-Raf-MAPK-ERK signalling pathway [15].
Calcitonin
The value is questionable because the reductions are small (approximately 1.0 mg/dl [0.25 mmol/L]) and transient [10].
Mithramycin
This was the mainstay of therapy for hypercalcaemia associated with cancer before the bisphosphonates became available. It remains effective, but its use is limited by potential adverse effects [10].
Gallium nitrate
Use is now limited as administration must be continuous and is laborious and less effective than previously thought.
Furosemide has been used in a fluid overloaded patient but not recommended due to potential complications and availability of drugs which inhibit bone resorption.’ 3
