drugs for pcos and endometriosis Flashcards
rotterdam criteria for pcos
- hyerandrogenism > 60 ng/dl
- amennorhea >3 months oligomennorhea > 45 days or 8 cycles
- polycystic ovaries,12 follicles in one or boh ovaries, 2-9 mm in diameter
symptoms/signs for pcos
- insulin resistance.
- alopecia, male-pattern baldness
- excessive hair growth
- acne,
- hirutism
- infertility
7.weight gain or difficulty losing weight
mentrual irregularaties are managed by
ocp- combined estrogen and progestins pills
mechanism of progestins to control menstrual abnormalities
suppresses the LH,
inhibits endometrial proliferation, preventing hyperplasia (controls menses)
(also reducing the unopposed action of estrogen)
cyproterone is a
Combination of ethinyl estradiol and cyproterone acetate
cyproterone acetate moa
blocks the androgen receptors so testosterone and 5 alpha reductase are not able to bind
cyproternoen acetate uses
maintains mentrual cycle, counteracts hyperandrogenism, treats hirutism
Drospirenone is a
analogue of spironolactone
Drospirenone moa
anti-mineralcorticoid activity, anti-androgenic activity
sodium excretion and water follows so estrogen related fluid retention is controlled
medroxyprogesterone moa
- decreasing GnRH production by negative feedback reducing testosterone and estrogen production by the ovary.
- induce menstruation in amenorrhoeic women
- in women not planning a preg, they counter the se of unoppsed estrogen
adverse effects of progestins
vaginal candiasis
breakthrough bleeding
dysmenorrhea
amennorhea,
breast tenderness
edema
ance
thromboembloic disorder
pulmonary embolism
spironolactone effects
dec production of testosterone as it inhibits the 17 alphahydroxylase enxyme thats is req for testosterone synthesis
combination of anti adrogens
ee+cyproterone acetate
ee+drospirnenone
ee+desogestrel(inhibits gnrh thus fsh and lh secretion reduces, establish reg menstrual cycle and the progestin part reduces risk of endometrial hyperlplasia)
insulin sensitizers moa
- increase the sensitivity of insulin receptors
- dec gluconeogenesis
- red absorption of glucose from the liver
4.increase shbg so free testosterone decreases
metformin moa
increases glucose uptake, lipogenesis
