Cyproterone acetate was developed subsequently to high-dose estrogen and is the only steroidal antiandrogen that has been widely used in the treatment of prostate cancer, [24] but it has largely been replaced by nonsteroidal antiandrogens, which are newer and have greater effectiveness, tolerability, and safety.
Flutamide (Eulexin): Marketed for the treatment of prostate cancer and also used in the treatment of acne, hirsutism, and hyperandrogenism in women. [3] [4] It has also been studied in the treatment of benign prostatic hyperplasia. [6] Now little-used due to high incidence of elevated liver enzymes and hepatotoxicity and the availability of ...
However, in spite of the combined AR antagonism and marked suppression of androgen levels by CPA (and hence a sort of CAB profile of antiandrogen action), monotherapy with an NSAA, CPA, or a GnRH analogue/castration all have about the same effectiveness in the treatment of prostate cancer, [94] [19] whereas CAB in the form of the addition of ...
Androgen deprivation therapy (ADT), also called androgen ablation therapy or androgen suppression therapy, is an antihormone therapy whose main use is in treating prostate cancer. Prostate cancer cells usually require androgen hormones, such as testosterone, to grow. ADT reduces the levels of androgen hormones, with drugs or surgery, to prevent ...
This is a list of antiandrogens, [1] or drugs that prevent the effects of androgens like testosterone and dihydrotestosterone (DHT). [2] It includes direct antagonists of the androgen receptor (AR), androgen synthesis inhibitors like 5α-reductase inhibitors and CYP17A1 inhibitors, and antigonadotropins like GnRH analogues, estrogens, and ...
Antiandrogens that are currently on the market are particularly useful for the treatment of prostate cancer during the early stages. However, prostate cancer often progresses to a hormone-refractory state in which the cancer progresses in the presence of continued androgen ablation or antiandrogen therapy. [9]
Bicalutamide is used primarily in the treatment of early and advanced prostate cancer. [1] It is approved at a dosage of 50 mg/day as a combination therapy with a gonadotropin-releasing hormone analogue (GnRH analogue) or orchiectomy (that is, surgical or medical castration) in the treatment of stage D2 metastatic prostate cancer (mPC), [2] [3] and as a monotherapy at a dosage of 150 mg/day ...
Used for androgen-dependent indications in women and transgender women, particularly in the United States where cyproterone acetate is unavailable. Studied in the treatment of benign prostatic hyperplasia but was found to be ineffective. Contraindicated in prostate cancer due to weak androgenic activity and stimulation of tumor growth.
