An Injectable Pharmaceutical to Relieve Bone Pain in Patients with Painful Cancer Metastases to the Bone

Up to 80% of Patients Report Pain Relief Lasting Months.

Generic Strontium Chloride Sr89 Injection USP (Strontium89) is a NON-OPIATE radioactive pharmaceutical injection to relieve bone pain in patients with painful skeletal metastases. In the body, Strontium acts similar to calcium and is preferentially taken up in osteoblastic tissue while the unabsorbed isotope is excreted in the urine the first 2 to 3 days following injection, clearing rapidly from the blood and selectively localizing in bone mineral. Uptake of strontium by bone occurs preferentially in sites of active osteogenesis; thus primary bone tumors and areas of metastatic involvement (blastic lesions) can accumulate significantly greater concentrations of strontium than surrounding normal bone.

Generic Strontium Chloride Sr89 Injection USP can be used in combination with opiate based drugs (or reduce the need for opiates) like Oxycotin®, Morphine, Percocet® as well as cancer therapeutic drugs. Clinical studies have demonstrated that the combination of alternating weekly chemohormonal therapies with Sr89 demonstrated a prolonged progression-free and overall survival with acceptable toxicity.

Generic Strontium89 injection is a pure beta emitter, and selectively irradiates sites of primary and metastatic bone involvement with minimal irradiation of soft tissues distant from bone lesions. The presence of bone metastases should be confirmed prior to therapy.

 When blastic osseous metastases are present, significantly enhanced localization of the radiopharmaceutical will occur with corresponding higher doses to the metastases compared with normal bones and other organs. Although responses can vary, pain relief typically begins 7 to 20 days after injection and lasts for months.
