nilutamide
antiandrogen
these drugs diffuse across cell membranes and bind to specific nuclear receptor proteins ; activated complex initiates RNA synthesis
steroid hormones
these drug compete with estrogen for binding in breast tissue
SERMs ( selective estrogen receptor modulators )
what is the most potent estrogen produced by the ovary; primary estrogen in premenopause
estradiol
this is the primary circulating estrogen after menopause
estrone
this is the estrogen produced by the placenta
estriol
clinical uses for estrogens
contraception, hormone therapy, stimulate development in young women with hypogonadism, tx of premature menopause, and tx of osteoporosis
AE of estrogens
uterine bleeding and endometrial cancer risk
Which SERM drug decreases bone resorption and overall bone turnover
raloxifine
clinical use of SERMS
palliative tx of metastatic breast cx , post mastectomy, tx of osteoporosis , infertility
AE of SERMS
hot flashes and nausea, many drug interactions, increased risk of thrombosis
what is the natural progestogen
progesterone
this hormone is produced in response to LH in males and females
progesterone
clinical use of progestogens
tx of hormonal def. , contraception, dysfunctional uterine bleeding,
AE of progestogens
HA, depression, weight gain, acne
which drug if admin. early in pregnancy can result in abortion of the fetus
mifepristone
which drug is used as an emergency contraceptive
levonorgestrel
AE of contraceptives
fluid retention, HA, nausea, vomiting, etc.
what is the most important androgen in humans
testosterone
this drug binds to a specific nuclear receptor ; hormone receptor complex binds to DNA and stimulates synthesis of specific RNAs and proteins
testosterone
clinical uses for androgens
androgenic effects, anabolic effects, endometriosis AE= masculinization, acne, growth of facial hair ( Females) and in males impotence, female cosmetic changes, stimulates growth of prostate
these drugs block the synthesis of androgens and their receptors
antiandrogens
which drugs are used to tx BPH
finasteride and dutasteride
which drug is used to tx prostatic carcinoma
flutamide
which drugs are effective oral tx for prostate cancer
Bicalutamide and nilutamide
