    A 67-year-old man complains of a bone-ache in his right hip which started a few weeks ago together with a change in his urination pattern-the flow was weak, and he has to urinate twice during the night. Various tests are done followed by a rectal examination of the prostate which shows it to be enlarged, firm, and nodular. Blood tests indicate a markedly elevated PSA level. On biopsy the prostate is carcinomatous. A bone scan confirms metastatic disease in the right hip. He is given drug A, IM, once every three months, which, on chronic treatment, results in a reduction in the number of gonadotrophinreleasing hormone receptors in the pituitary and castrate levels of testosterone in the testes. He also receives drug B three times daily, which blocks androgen receptors. Which of the following best identifies drug A and drug B?
    • A. 

      Drug A is leuprolide; Drug B is flutamide

    • B. 

      Drug A is finasteride; Drug B is cyproterone

    • C. 

      Drug A is leuprolide; Drug B is spironolactone

    • D. 

      Drug A is finasteride; Drug B is flutamide

    • E. 

      Drug A is estradiol; Drug B is leuprolide
