For which conditions is this drug approved? Chromic phosphate is FDA-approved to treat the leaking of fluid (effusion) into the peritoneum (sac surrounding the abdominal organs) or pleura (sac surrounding the lungs) as a result of advanced cancer. It is important for patients to remember that physicians have the ability to prescribe medication for conditions other than those for which the drug has been approved by the FDA. Patients who have received a prescription of this drug for a condition other than which it is approved may wish to discuss this issue with their physician.
What is the mechanism of action? Chromic phosphate belongs to a group of agents classified as radiopharmaceuticals. Chromic phosphate produces its anti-cancer effects by emitting radiation to tissues surrounding it.
How is chromic phosphate typically given (administered)? Chromic phosphate is administered by catheter into a body cavity (intracavitary) and the dose depends on several factors, including the condition being treated, the size of the patient, the particular regimen being used and the overall health of the patient.
How are patients typically monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with chromic phosphate. Typically, blood will be drawn to check levels of blood cells and to monitor functions of some organ systems, such as the kidneys or liver. Patients may also undergo physical examinations, scans or other measures to assess side effects and response to therapy.
