Q

what is the MOA of exogenous estrogen?

A

bind to the estrogen receptors in various tissues and is transferred to the nucleus which results in increase gene and protein expression that give the physiological responses of estrogen

Q

estrogen effects on lab results:

cholesterol
antithrombin III
osteoclastic bone activity
triglycerides
clooting factoris
platelet aggregation
sodium/fluid retention
thyroid binding TBG

A

estrogen will work to decrease cholesterol LDL/TC (this is good)

it will decrease antithrombin III activity (break up a clot)

will decrease osteoclastic acivity

will increase HDL and triglycerides (good)

will increase clotting factors and platelet aggregation (higher chance of clotting-not good)

increase sodium and fluid rentention (bloating and puffy)

increase thyroid binding globulin (TBG)

Q

what is a benefit singular to combined MHT (estrogen and progestin in a patient with a uterus)

Study These Flashcards
A

decerase in colorectal cancer

23
Q

what is a benefit to just estrogen MHT

Study These Flashcards
A

decrease in invasive breast cancer

24
Q

what are some harms associated with both combination MHT and estrogen only MHT

Study These Flashcards
A

dementia
gall bladder disease
stroke
VTE
urinary incontience

25
what are some harms associated with just combined MHT
increased risk of breast cancer (invasive) and increased risk of coronoary heart disease
26
MHT very effectively minimizes/treates _ symptoms and _ changes
vasomotor symptoms and vaginal changes
27
MHT should not be used to prevent _ or _
CVD or dementia
28
MHT benefit on bone and colon cancer are outweighed by _
all the other risks
29
for younger women with menopausal symptoms can you give them MHT?
yes, it can treat troubling menopausal symptoms in the relatively young and within 10 years of menopause you can individualize this to your patients they dont have to be on it forevere start with patch over oral therapy
30
for women with vaginal symptoms only the preffered treatment is?
low dose vaginal estrogen topicals
31
both estrogen alone therapy and estrogen with progestin increases risk of _
blood clots ## Footnote counsel your patients
32
alhtough risks of blood clots and stroke increase with either MHT, risk is less in _ year old age group
50-59 year old
33
there is an increased risk of _ cancer seen within 2-4 uears of continuous estrogen with progestin therapy
breast ## Footnote for women at risk for breast cancer, maybe shouldnt give them this
34
MHT take home messages use the _ (lowest/highest) dose possible to control symptoms treat for the _ (shortest/longest) duration possible and re-evaluate at least yearly )
lowest shortest | make sure you document everything ## Footnote risks and benefits of MHT are essentially eliminated several years after MHT is stopped
35
what are SERMS
selective estrogen receptor modulators
36
what is the goal of a SERM
to be proestrogenic at select tissues like the bone, vagina, and hotflashes but to be anti estrogenic at other sites like the breast or the endometrium
37
whar are TSECS
tissue selective estrogen complexes
38
what is the goal of TSECs
to combine the unique elements of a SERM with an estrogen compound
39
SERMs are replacing progestin actions of traditional progestin- inclusive
MHT
40
what are the SERMs we need to know?
ospemifene clomiphene
41
what is a TSEC we need to know about?
Bazedoxifene this is a combo with conjugated estrogen and selective receptor modulator ## Footnote not available in a single ingredient compound
42
OSpemifene indications (serm)
dypareunia (symptom of menopause due to vaginal atropy) vaginal dryness ## Footnote if vaginal dryness is the only issue maybe just topical
43
MOA of ospemifene (SERM)
functions as an estrogen agonist by binding to ER in the vagina but anti- estrogenic at the breast increases vaginal secretions, decreases vaginal pH, reduces pain during intercourse, increase superifical cell growth
44
side effects of ospemifene
hot flashes, estrogenic effects of coagulation/endometrial thickening and hyperplasia
45
contrainications of ospemifene
AUB, thromboembolic events, estrogen related neoplasia
46
bazedoxifen is used in women with a _ uterus
intact
47
bazedoxifence with a conjugate estrogen is used for?
menopausal symptoms in women with a uterus prevention of post menopausal osteoporosis in women with a uterus
48
MOA of bazedoxifene (TSEC)
antagonistic affect in the endometrium (prelaces the progestin concept in tradiational MHT) and in breast tissue agonist/estrogenic physioloigcal effect in bone does not stimulate endometrial proliferation destroys HER2 malignant cells
49
TSECS with Conjugated estrogen have replaced what
traditional MHT therapy with progestin this is because they are anti-estrogenic at the places where unapposed estrogen could create problems ## Footnote less vaginal bleeding compared to progestin therapy
50
side effects of bazedoxifene
all estrogen related side effects: DVT, dementia, stoke, gall bladder disease, urinary incontinence specific: worsening of hot flashes contraindicated in all estrogen situations
51
what is clomiphene
an anti estrogen SERM that is used in infertility and anovulatory women, irregular ovulation, luteal phase defects, PCOS used in infertility !
52
MOA of clomiphene
blocks inhibitory/negative feedback actions of estrogen oon the hypothalamus preventing estrogen from lowering GNRH on the pituitary gonadotropin release (LH and FSH) increases gonadotropin (LH and FSH) secretion to help stimulate ovaries to develop oocyte follicles ## Footnote given orally between cycle days 5 and 9
53
side effects of clomiphene used in infertility
1. multiple gestations 2. ovarian cysts 3. hot flashes 4. luteal-phase dysfunction (inadequate progesterone production)
