Q

progestin

Study These Flashcards
A

bind progesterone receptor

decreased growth and increased vasc of endometrium

20
Q

hormone replacement therapy

Study These Flashcards
A

relief sx of post-menopause

osteoporosis - more estrogen - decrease osteoclasts

21
Q

unopposed estrogen therapy

Study These Flashcards
A

increased risk endometrial cancer

-so combine with progesterone

22
Q

mifepristone

Study These Flashcards
A

RU-486

competitive inhibitor of progestins at progesterone receptor

23
Q

termination of pregnancy

Study These Flashcards
A

mifepristone - RU-486 - progesterone receptor inhibitor

misoprostol - PGE1 - prostaglandin

24
Q

oral contraception

Study These Flashcards
A

estrogen and progestins

  • inhibit LH/FSH - prevent estrogen surge
  • no LH surge - no ovulation

progestins - also - thick cervical mucus and inhibit endometrial proliferation

25
CI for oral contraception
smoker >35yo | hx of thromboembolism or stroke
26
terbutaline
beta2 agonist relax uterus contractions
27
ritodrine
beta2 agonist relax uterus contraction
28

synthetic androgen | -partial agonist at androgen receptor
29
adverse danazol
hirsutism, acne, masculinization, weight gain, edema
30
testosterone
agonist androgen receptors
31
tx hypogonadism and promote secondary sex characters in boy
testosterone
32
adverse testosterone
gonadal atrophy premature closure epiphyseal plates- short stature
33

finasteride
35
flutamide
nonsteroid competitive inhibitor at androgen receptors tx prostate carcinoma
36
ketoconazole
inhibit steroid synthesis inhibit 17,20 desmolase
37
spironolactone
inhibit steroid binding, 17a hydroxylase, and 17,20 desmolase
38
tx of androgenic sx of PCOS
ketoconazole and spironolactone
39
tamsulosin
a1 antagonist -selective for a1-AD - in prostate smooth muscle relaxation
40
tx of BPH

41
sildenafil
PDE5 inhibitor
42
vardenafil
PDE5 inhibitor
43
tadalafil

44
PDE5 inhibitor
increased cGMP, smooth m relaxation corpus cavernosum increased blood flow - erection
45
