The Modern FDA Description of Strontium 89 as used in Current Oncology

The current pharmacological description of Strontium 89
confirms Percher’s findings of the 1940s. This description
shows the nature of the substance spread across the
biosphere where ever atomic weapons were detonated, and
where ever power reactors are allowed to vent into the
“Clinical Description of Strontium Chloride SR 89

Commonly used brand name(s): Metastron.
Bone lesions, metastatic (treatment) Strontium
chloride Sr 89 is indicated in the palliative treatment
of bone pain in selected patients with multiple areas
of skelal metastases from carcinoma of the prostate,
breast and possibly, from other carcinomas.

Precautions to Consider:
Thirty-three out of 40 rats receiving 10 consecutive monthly
doses of either 250 or 350 micro curies per kg of body
weight of strontium 89 developed malignant bone tumors
after a latency period of approximately 9 months.
Adequate and well-controlled studies with strontium chloride
Sr 89 have not been done in humans. Radio-pharmaceuticals
are generally not recommended for therapeutic use during
pregnancy because of the risk to the fetus from radiation
exposure. Strontium chloride Sr 89 would be expected to
cause adverse effects, such as bone marrow toxicity, in the
To avoid the possibility of fetal exposure to radiation, in
those circumstances in which the patient’s pregnancy
status is uncertain, a pregnancy test will help to prevent
inadvertent administration of their preparation during
FDA Pregnancy Catergory D
Breast Feeding
Strontium Chloride Sr 89 acts as a calcium analog
and is expected to be distributed into breast milk.
Because of the potential risk to the infant from
radiation exposure, complete cessation of nursing is
recommended after strontium chloride Sr 89 has
been administered.” End quote. (Source:,
