Due to its progestogenic (and by extension antigonadotropic) activity, CPA is able to suppress circulating testosterone levels by 70 to 80% in men at high dosages. [ 25 ] [ 94 ] In contrast, NSAAs increase testosterone levels by up to 2-fold via blockade of the AR , a difference that is due to their lack of concomitant antigonadotropic action ...
Eplerenone may have a lower incidence than spironolactone of sexual side effects such as feminization, gynecomastia, impotence, low sex drive and reduction of size of male genitalia. [18] This is because other antimineralocorticoids have structural elements of the progesterone molecule, causing progestogenic and antiandrogenic outcomes. [ 4 ]
[30] [70] [71] [72] Although spironolactone is said to be a relatively weak inhibitor of 17α-hydroxylase and 17,20-lyase, [73] [30] at least compared to more potent steroidogenesis inhibitors like ketoconazole and abiraterone acetate (which can reduce testosterone concentrations to castrate levels), this action may contribute to a significant ...
They are common during spironolactone therapy, with 10 to 50% of women experiencing them at moderate doses and almost all experiencing them at a high doses. [86] [111] For example, about 20% of women experienced menstrual irregularities with 50 to 100 mg/day spironolactone, whereas about 70% experienced menstrual irregularities at 200 mg/day. [63]
A nonsteroidal antiandrogen (NSAA) is an antiandrogen with a nonsteroidal chemical structure. [1] [2] [3] They are typically selective and full or silent antagonists of the androgen receptor (AR) and act by directly blocking the effects of androgens like testosterone and dihydrotestosterone (DHT).
“A doctor might recommend Tylenol over ibuprofen for patients who need pain relief but cannot tolerate NSAIDs due to stomach issues, risk of bleeding, or cardiovascular concerns,” says Walia ...
Case in point — 30 to 50 percent of men experience male pattern baldness by age 50. Hair loss is an unfortunate, yet real, part of growing older, and if you’re still young, you may think you ...
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 ...
