Patient drug information

History of changes in FDA indication

  • 1989-01-27: Initial FDA approval for use in combination with LHRH agonistic analogs (such as leuprolide acetate) for the treatment of metastatic prostatic carcinoma (stage D2). To achieve the benefit of the adjunctive therapy with EUFLEX, treatment must be started simultaneously using both drugs. EUFLEX Tablets are also indicated as an adjunctive therapy to orchiectomy, in order to achieve complete androgen blockade. (Based on SWOG-8494)
  • 1989-01-27: Also approved in combination with LHRH agonists are also indicated prior to and during definitive external beam radiotherapy for patients with bulky locally advanced Stage B2 and Stage C prostatic carcinoma. (Based on Pilepich et al. 1995)
