hot flashes
vaginal discharge
amenorrhea
menstrual changes
275
What is the box warning associated with tamoxifen?
stroke

prphylaxis of breast cancer in high risk patients
osteoporosis
278
what is the MOA of raloxifene?
competative antagonist on estrogen receptors in the following tissues:
breast- decrease breast cancer cell growth
endometrium and myometrium- decrease proliferation
279
Raloxifene is on agonist on the estrogen receptor in which tissue type?
bone tissue- inhibits osteoclasts
280
What are the AE of raloxifene?
hot flashes
flu syndrome

pregnancy/lactation
active history of thromboembolic events
283
What class is clomephene?
antiestrogens
284
What is the MOA of clomiphene?
blocks hypothalamic estrogen receptors inhibiting negative feedback and increasing release of FSH and LH to trigger ovulation
285
What are the AE associated with clomiphene?
ovarian hyperstimulation
increased incidence of multiple births
ovarian cysts
hot flashed
blurred vision
286
What are the steroidal aromatase inhibitors?
exemestane
287
What are the nonsteroidal aromatase inhibitors?
anastrozole
letrozole
288
What is the MOA of aromatase inhibitors?
inhibits aromatase which decreases conversion of androstenedione to estrone, decreased conversion of testosterone to estradial leading to decreased tumor growth
289
What are the uses for aromatase inhibitors?
post menopausal estrogen receptor positive breast cancer
290
What specifically is letrozole used for?
ovulation induction
291
What are the AE of aromatase inhibitors?
hot flashes
vaginal dryness
myalgia or arthralgia
292
What are the CI of aromatase inhibitors?
women who are or may become pregnant
premonpausal women
293
What is a warning for aromatase inhibitors?
risk of osteoporosis with long term use
294
What must be taken with progestins in order to lower the chance of getting endometrial cancer in women who still have a uterus?
estrogens
295
What is the MOA of progestins?
inhibits GnRH and LH secretion- no ovulation
inhibits endometrial proliferation- prevents implantation of the embryo
changes cervical mucous and impairs fallopian tube peristalsis
inhibits follicular maturation
296

medroxyprogesterone acetate
megestrol acetate
297
