1.
WHAT QUADRAMET IS AND WHAT IT IS USED FOR
Quadramet is a medicinal product for therapeutic use only.
This radiopharmaceutical is used for the treatment of bone pain due to
your disease.
Quadramet has a high affinity for skeletal tissue. Once injected it
concentrates in bone lesions.
Because Quadramet contains small amounts of a radioactive element,
samarium-153, radiations are
delivered locally to the bone lesions, allowing to develop the
palliative action on bone pain.
2.
WHAT YOU NEED TO KNOW BEFORE YOU TAKE QUADRAMET
DO NOT TAKE QUADRAMET:
•
If you are allergic to ethylene diamine tetramethylene phosphonic acid
(EDTMP) or similar
phosphonate compounds or any of the other ingredients of this medicine
(listed in section 6),
•
If you are pregnant,

Quadramet 1.3 GBq/mL solution for injection.
2.
QUALITATIVE AND QUANTITATIVE COMPOSITION
Each ml of solution contains 1.3 GBq Samarium (
153
Sm) lexidronam pentasodium at the reference date
(corresponding to 20 to 80 µg/ml of samarium per vial)
Samarium specific activity is approximately 16 – 65 MBq/µg of
samarium.
Each vial contains 2-4 GBq at the reference date.
Samarium-153 emits both medium-energy beta particles and an imageable
gamma photon, and has a
period of 46.3 hours (1.93 days). The primary radiation emissions of
samarium-153 are shown in
Table 1.
