Repro Flashcards
Leuprolide
1) Use: Infertility (Pulsatile), Prostate Cancer (continuous + flutamide), uterine fibroids (continuous), precocious puberty (continuous)
2) Class/MOA: GnRH analog, pulsatile use=agonist properties, continous use=antagonist properites because downregulates GnRH receptor in pituitary causing decrease FSH/LH
3) Side effects/ADEs: Antiandrogen, N/V
4) Fun Facts Leuprolide can be used in lieu of GnRH
Testosterone, methyltestosterone
1) Use: Hypogonadism, development secondary sex characteristics, stimulates anabolism to promote recovery after burn or injury
2) Class/MOA: Agonist at androgen receptor
3) Side effects/ADEs: Masculinization in females, reduces intratesticular testoerone b/c inhibit relase of LH causing gonadal atropy, premature closing epiphyseal plate, increase LDH, decrease HDL
Finasteride
1) Use: BPH, hair growth male pattern baldness
2) Class/MOA: Antiandrogen/5alpha reductase inhibitor (decrease conversion of testosterone to DHT)
3) Side effects/ADEs: Female breast growth
Flutamide
1) Use: Prostate carcinoma
2) Class/MOA: Antiandrogen/ nonsteroidal competitive inhibitor of androgesn at testosterone receptor
Ketoconazole
1) Use: Polycystic ovarian syndrome to prevent hirsutism
2) Class/MOA: Antiandrogen/ inhibits 17,20 desmolase and inhibits steroid synthesis
3) Side effects/ADEs: Gynecomastia and amenorrhea
Sprionolactone
1) Use: Polycytic ovarian syndrome prevent hirsuitsm
2) Class/MOA: Antiandrogen/inhibits steroid binding
3) Side effects/ADEs: Gynecomastia and amenorrhea
Estrogens (ethinyl estradiol, DES, mestranol)
1) Use: Hypogonadism, ovarian failure, menstural abnormalities, HRT postmenopausal, men with androgen dependent prostate cancer
2) Class/MOA: Binds estrogen receptors
3) Side effects/ADEs: Increase risk endometrial cancer, bleed postmenopausal, vaginal clear cell adenocarcinoma if exposed to DES in utero, increase risk thormbi
4) Fun Facts: contraindicated if ER positive breast cancer or history of DVTs
Clomiphene
1) Use: Infertility and PCOS
2) Class/MOA: Selective estrogen receptor modulator (SERMs)/ partial agonist at estrogen receptors in hypothalamus, prevents normal feedback inhibition and increases relase of LH and FSH from pituitary and stimulates ovulaiton
3) Side effects/ADEs: Hot flashes, ovarian enlargement, multiple simultaneous pregnancies, visual disturbances
4) Fun Facts: Remember, infertile, take clomiphene have twins, seeing double
Tamoxifen
1) Use: Treat and prevent recurrence ER positive breast cancer
2) Class/MOA: SERM/Antagonist on breast tissue
Raloxifene
1) Use: Osteoporosis
2) Class/MOA: SERM/Agonist on bone, reduces resorption of bone
Hormone Replacement Therapy
1) Use: Relief/prevent menopausal symptoms (hot flashes, vaginal atrophy) and osteoporosis
2) Class/MOA:
3) Side effects/ADEs: Unopossed estrogen replacement therapy (ERT) causes increase endometrial cancer so add progesterone, possible increase in CV risk
Anastrozole/ exemestane
1) Use: Postmenopausal women with breast cancer
2) Class/MOA: Aromatase inhibitor
Progestins
1) Use: OCP, Mirena IUD, treatment of endometrial cancer and abnormal uterine bleeding
2) Class/MOA: Binds progesterone receptors, reduce growth and increase vascularizaiton of endometrium
4) For OCP have to take at same time everyday so not as effective contraceptive
Mifepristone (RU 486)
1) Use: Terminiation of pregnancy +misoprostol (PGE1)
2) Class/MOA: Competitive inhibitor of progestins at progesterone receptors
3) Side effects/ADEs: Heavy bleeding, GI effects (nausea, vomiting, anorexia), abdominal pain
Oral contraception (synthetic progestins, estrogen)
1) Use: Prevent pregnancy
2) Class/MOA: Estrogen and progestins inhibit LH/FSH and prevent estrogen surges so no LH surge and no ovulaiton. Progestins cause thickenign of cervical mucus, limiting access of sperm to uterus. Also inhibits endometrial proliferation, making endometirum less suitable for implanation of embryo
3) Side effects/ADEs: Contraindicated in smokers >35 yo becuase increase risk of DVT and CV events, patients with history of thormoembolism and storke or estrogen dependent tumor
