Module 2: Chapter 52 Drugs Affecting Women's Health and Sexuality Flashcards
what are the female sex hormones responsible for
producing female sex characteristics
developing the female reproductive systme
maintaining pregnancy
what are the two types of female sex hormones
estrogen
progestin
true or false: both female sex hormones are not steroidal compounds
false: they are steroidal
when are female sex hormones produced and where
ovaries begin to secrete at puberty and the placenta secretes during pregnancy
adrenal cortex also secretes estrogen and progestin but in much smaller amounts
how does the menstral cycle work
low estrogen and progesterone levels cause stimulation
GnRH is produced
release of FSH and LH
ovulation
development of corpus luteum
estrogen and progesterone levels rise to high levels
fertilization or non fertilization
what are the three options that occur in the menstral cycle when their are high estrogen and progesterone levels
fertilization
no fertilization
suppression and indirect shutoff of FSH and LH (negative feedback)
what happens if fertilization occurs
production of progesterone and estrogen by placenta
high levels of estrogen and progesterone maintained
suppression and indirect shutoff of FSH and LH (negative feedback)
what happens if no fertillization occurs
disintigration of corpus luteum
drop in levels of progesterone and estorgen
low levels cause stimulation and cycle repeats
will a women who is deficient in endogenous sex hormones can she still experience normal sexual development
no
what happens to a womans estrogen levels during menopause
estrogen levels drop and woman experiences several changes
in postmenopausal women the loss of estrogen contribute to the development of what
osteoporosis
what is osteoporosis characterized by
low bone mineral density
what is the leading cause of osteoporosis
deficiency of sex hormones
is there many different types of exogenous estrogen that differ in terms of indications, route of administration and pharmacokinetics
yes
what are the different routes of administration for exogenous estrogens
oral
IM
transdermal
topcial (vaginal creams)
what are most of these estrogens used for
correction of low endogenous estrogen or in birth control products combined with progestins
what is the prototype drug for estrogen
conjugated estrogen (premarin)
conjugated estrogen is primarily used in what
hormone replacement therapy
where is conjugated estrogen metabolised
liver
where is conjugated estrogen excreted
kidneys
what does conjugated estrogen do
stimulates the development of the female sex organs and secondary female sexual characteristics
what are the contraindications for conjugated estrogen
black box warning for increase of risk of cardiovascular events
what are some adverse effects for conjugated estrogen?
incr. risk for stroke and heart disease breakthrough bleeding headache N/V bloating abdominal cramps chloasma (brown patches on the skin)
what should be assessed for when giving conjugated estrogen
assess BP and breast fr any masses
check pts age
why is the environment important when giving conjugated estrogen
causes photosensitiviity
how can the therapeutic effects of conjugated estrogen be maximized
administer conjugated estrogen cyclically
