Repro drugs Flashcards
Leuprolide MOA
GnRH analog
Pulsatile = agonist action
Continuous = antagonist action
Pulsatile leuprolide for:
infertility
continuous leuprolide for:
prostate cancer, fibroids, precocious puberty
Leuprolide AE
Anti-androgens (if continuous), N/V
Synthetic estrogens:
ethinyl estradiol, DES, mestranol
estrogen use in men:
androgen-sensitive prostate cancer
estrogen toxicity:
Endometrial cancer, post-meno bleeding, thrombi, clear cells adenocarcinoma in vagina of kids whose moms took DES. Contraindicated in ER+ breast cancer, or DVT Hx
Clomipine MOA
SERM; hypothalamic estrogen receptor antagonist; so prevents feedback inhibition, so increases LH and FSH
Clomiphene use
induce ovulation (via LH and FSH surge) in anovulatory states (i.e PCOS)
Clomiphene AE
VISUAL DISTURBANCES, hot flashes, ovarian enlargement, multiple simultaneous pregnancies
Tamoxifen use/MOA
agonist: uterus and bone
antagonist: breast
use: ER+ treat and prevent recurrence of ER+ /PR+ great cancer
Tamoxifen AE
endometrial cancer and thromboembolisms
Raloxifen use/MOA
agonist: bone
antagonist: breast and uterus
use: osteoporosis (ER+ prevention)
Raloxifen AE
thromboembolisms
HRT use
relief of menopausal symptoms (hot flashes, vaginal atrophy), osteoporosis
HRT AE
endometrial cancer (add progesterone to decrease risk). Maybe increase CV risk
Anastrazole/exemestane MOA/use
aromatase inhibitor (decrease E). Used in post-menopausal ER+ breast CA
Progestins MOA and use
MOA = decrease growth and vascularization of endometrium. Use = OCP, rx of endometrial CA, rx of abnormal uterine bleeding
Mifepristone (RU-486) MOA
COMPETITIVE progestin-R inhibitor
