Medical uses
Prostate cancer
Nilutamide is used in prostate cancer in combination with a gonadotropin-releasing hormone (GnRH) analogue at a dosage of 300 mg/day (150 mg twice daily) for the first 4 weeks of treatment, and 150 mg/day thereafter. It is not indicated as a monotherapy in prostate cancer. Only one small non-comparative study has assessed nilutamide as a monotherapy in prostate cancer.Nilutamide has been used to prevent the effects of the testosterone flare at the start of GnRH agonist therapy in men with prostate cancer. Transgender hormone therapy
Nilutamide has been studied for use as a component of feminizing hormone therapy for transgender women. It has been assessed in at least five small clinical studies for this purpose in treatment-naive subjects. In these studies, nilutamide monotherapy at a dosage of 300 mg/day, induced observable signs of clinical feminization in young transgender women (age range 19–33 years) within 8 weeks, including breast development, decreased body hair (though not facial hair), decreased morning erections and sex drive, and positive psychological and emotional changes. Signs of breast development occurred in all subjects within 6 weeks and were associated with increased nipple sensitivity, and along with decreased hair growth, were the earliest sign of feminization.Nilutamide did not change the size of the prostate gland (which is the same as with high-dosage cyproterone acetate and ethinylestradiol treatment for as long as 18 months), but was found to alter its histology, including increased stromal tissue with a significant reduction in acini and atrophic epithelial cells, indicating glandular atrophy.
