ketotifen: as a cardioprotective agent in breast cancer patients receiving anthracycline-containing chemotherapy

Conditions: Breast Cancer; Iron Chelation

Summary: the objective of our study was to evaluate the expected cardioprotective effects of ketotifen due to its activity as an iron-chelating agent previously uncovered by us in the in vitro chemical test which included in the study, when used in patients receiving anthracyclines for the treatment of breast cancer. the study was a randomized : , prospective controlled trial : , and the patients were identified by coded numbers to maintain privacy. eligible patients (111) fulfilled the criteria. control group: 55 patients received their standard therapy (anthracycline-containing chemotherapy without ketotifen). ketotifen group: 56 patients received anthracycline-containing chemotherapy plus ketotifen as a cardioprotective agent. ketotifen will be given orally as one tablet (1 mg/tablet) 3 times daily, before and during the chemotherapeutic cycle for 6 cycles of treatment. blood samples were obtained from all patients, and echocardiography two times for each patient at baseline and after 6 months (ef%).
