Drugs Used to Prevent Preterm Labor

Hydroxyprogesterone Caproate (Makena): • Only approved drug for prevention of preterm labor •Singleton birth, hx of at least one preterm birth •Contraindicated: uncontrolled HTN, liver cancer, liver disease, hx thrombosis, cholestatic jaundice of pregnancy, undiagnosed uterine bleeding, breast cancer or other hormone -sensitive cancer ABX :Treat bacterial vaginosis = decreased risk preterm labor

preterm labor

before 37 weeks gestation

In menopausal women, HT can reduce

bone resorption and slow the development of osteoporosis. More importantly, HT can decrease the risk of osteoporotic fractures.

Menopausal therapy with estrogen alone might increase

breast cancer risk. If so, the risk for most women appears to be small, especially with short-term use.

-foreign body sensations -coital problems -ring expulsion -vaginal symptoms -headache -emotional lability

common reasons for discontinuing the ring

PDE5 inhibitors

considered first line treatment for ED

The purpose of estrogen in both regimens is to

control menopausal symptoms by replacing estrogen that has been lost owing to menopause. The progestin is present for one reason only: to counterbalance estrogen-mediated stimulation of the endometrium, which can lead to endometrial hyperplasia and cancer.

In the human male, small amounts of testosterone are

converted into estradiol and estrone by the testes.

•hands with soap and warm water after every application. •cover the application site with clothing after the gel has dried. •wash the application site before skin-to-skin contact with another person. • Women and children should avoid skin-to-skin contact with application sites on gel users. • Women and children who make accidental contact with a gel application site should wash contaminated skin immediately.

what are the requirements (only way) for Clomiphene to induce ovulation?

many women are discontinuing treatment. There are two basic methods:

immediate cessation and tapering slowly. However, there are no controlled studies to indicate which option might result in fewer symptoms.

Testosterone pellets [Testopel]

implanted subdermally in the hip area or abdominal wall lateral to the umbilicus.

Strong data show that HT using EPT increases both

incidence of breast cancer and breast cancer mortality.

HT increases the risk of

incontinence in women who are not incontinent and makes incontinence worse in women who already are.

Conventional therapy (males, children, pregnant women, and women with suspected upper tract involvement)

indicated for all patients who do not meet the criteria for short-course therapy

Carboprost

However, the use of short-term HT to manage menopausal symptoms

is still deemed appropriate, provided women use the smallest effective dosage for the shortest time needed.

no!

Estradiol

is the principal endogenous estrogen.

Progesterone

is the principal endogenous progestational hormone.

The benefits of long-term HT to prevent chronic disorders do not

justify the risks.

less effective and are more likely to cause irregular bleeding

Acute cystitis

lower UTI that occurs most often in women of childbearing age

The principal noncontraceptive application of estrogens and progestins

Complicated UTIs

occur in males and females who have a structural or functional abnormality of the urinary tract that predisposes them to developing infection

By activating estrogen receptors, tamoxifen protects against what?

osteoporosis and has a favorable effect on serum lipids. However, receptor activation also increases the risk of endometrial cancer and thromboembolism.

For most women, the benefits of long-term HT for disease prevention do not

outweigh the risks, and hence long-term HT should generally be avoided.

Periodic liver function tests

patients should have what type of tests done while taking androgens?

Two anterior pituitary hormones—follicle-stimulating hormone (FSH) and luteinizing hormone (LH)—

play central roles in regulating the menstrual cycle.

Human chorionic gonadotropin (hCG)

polypeptide hormone produced by the placenta

Estrogen increases the risk of breast cancer primarily in

postmenopausal women who are using estrogen combined with a progestin. Estrogen does not cause breast cancer--it only promotes the growth of a cancer that already exists, and then only if the cancer is estrogen receptor-positive.

alpha blockers

preferred for men with relatively small prostates

Progesterone levels increase during

pregnancy. These high levels suppress contraction of uterine smooth muscle and thereby help sustain pregnancy.

abruptio placentae

premature separation of the placenta from the uterine wall can be from trauma

GnRH antagonists

prevent premature LH release and thereby eliminate the chance of premature ovulation (with menotropins or follitropin [FSH])

•Magnesium Sulfate

previously heavily used. Research says no clinically significant tocolytic effect, but recommended b/c can decrease risk for cerebral palsy with preterm delivery AE: hypotension, flushing, HA, dizziness, lethargy, dry mouth, pulmonary edema, hypocalcemia, altered LOC MONITOR: big thing to assess is DTR before and during if they weaken is a sign of toxicity

nexplanon

subdermal Etonogestrel Implants

Unfortunately, progesterone also

suppresses contraction of GI smooth muscle, which leads to prolonged transit time and constipation. In the breast, progesterone promotes growth and proliferation of alveolar tubules (acini), the structures that produce milk.

The principal benefits of postmenopausal estrogen/progestin therapy (EPT) and estrogen therapy (ET) are

suppression of menopausal symptoms and prevention of osteoporosis.

Prolonged use of estrogens alone by postmenopausal women is associated

with an increased risk of endometrial carcinoma. However, when estrogens are used in combination with a progestin, there is little or no risk of uterine cancer.

Drugs for Cervical Ripening & Induction of Labor

•>22% deliveries are induced in US •Post-term pregnancy- most common reason •Indications for early induction: •Abruptio placenta (placenta separates from uterus) •Premature rupture of membranes •Gestational hypertension •Preeclampsia/Eclampsia •Maternal medical conditions •Fetal compromise •Fetal demise

Estrogens support

the development and maintenance of the female reproductive tract and secondary sex characteristics.

The first half of the menstrual cycle (days 1 through 14) is called

the follicular phase, and the second half is called the luteal phase. One full cycle typically takes 28 days.

Menopausal hormone therapy (HT) consists of low doses of estrogen (with or without a progestin) taken to compensate for

the loss of estrogen that occurs during menopause.

Hormone therapy in postmenopausal women is

the most common noncontraceptive use of estrogens.

Alprostadil pellets [Muse]

the only ED drug that is approved for twice-daily use, is inserted into the urethra

Progesterone is produced by

the ovaries and the placenta. Ovarian production occurs during the second half of the menstrual cycle.

The principal concerns with estrogen therapy are

the potential for endometrial hyperplasia, endometrial cancer, and cardiovascular events.

In premenopausal women, the ovary is

the principal source of estrogen

Postmenopausal ET and EPT increase

the risk of cholecystitis.

In addition, estrogen alone increases

the risk of coronary heart disease and myocardial infarction, but only in women older than 60 years.

In postmenopausal women, therapy with estrogen alone or estrogen combined with a progestin may increase?

the risk of ovarian cancer.

Progesterone secreted during

the second half of the menstrual cycle converts the endometrium from a proliferative state into a secretory state. If implantation does not occur, progesterone production by the corpus luteum declines. The resultant fall in progesterone levels is the principal stimulus for the onset of menstruation.

-suppresses endometriosis (not a cure) -uterine fibroids -central precocious puberty -advanced prostate cancer

therapeutic uses of Leuprolide [Lupron Depot, Eligard]

Beyaz, Rajani, and Safyral

these combination OCs contain levomefolate, a metabolite of folic acid (reduce the risk of fetal neural tube defects)

The primary noncontraceptive use of progestins is

to counteract the adverse effects of estrogen on the endometrium in women undergoing HRT.

Ortho Evra and Xulane

transdermal contraceptive patches

eclampsia

Nausea is the most frequent

undesired response to the estrogens.

Alprostadil [Caverject, Caverject Impulse, Edex]

used for direct injection into the corpus cavernosum

Dinoprostone and misoprostol

used to initiate ripening of the cervix before induction of labor.

Clomiphene [Clomid, Serophene]

used to promote follicular maturation and ovulation in selected infertile women

uterine tachysystole

uterus contracts more then its supposed to •>5 contractions in 10 min (normal rate ≤5 contractions in 10 min) which can lead to fetal distress •fetal HR monitoring should be done continuously

In postmenopausal women, estrogen, used either alone or combined with a progestin, increases the risk of

venous thromboembolism (VTE) and stroke

Raloxifene

very similar to tamoxifen. The principal difference is that raloxifene does not activate estrogen receptors in the endometrium, and hence does not pose a risk of uterine cancer.

Tamoxifen

was the first SERM to be widely used. By blocking estrogen receptors, tamoxifen (and its active metabolite, endoxifen) can inhibit cell growth in the breast. As a result, the drug is used extensively to prevent and treat breast cancer.

yes!

are nitrofurantoin and methenamine only used for UTIs?

The two basic regimens for HT are

(1) estrogen alone and (2) estrogen plus a progestin.

In the ovary, the following sequence occurs:

(1) several ovarian follicles ripen; (2) one of the ripe follicles ruptures, causing ovulation; (3) the ruptured follicle evolves into a corpus luteum; and (4) if fertilization does not occur, the corpus luteum atrophies.

HT has only three approved indications:

(1) treatment of moderate to severe vasomotor symptoms associated with menopause, (2) treatment of moderate to severe symptoms of vulvar and vaginal atrophy associated with menopause, and (3) prevention of postmenopausal osteoporosis.

In the uterus, these events occur:

(1) while ovarian follicles ripen, the endometrium prepares for nidation by increasing in thickness and vascularity; (2) after ovulation, the uterus continues its preparation by increasing secretory activity; and (3) if nidation fails to occur, the thickened endometrium breaks down, causing menstruation, and the cycle begins anew.

Indomethacin

- Cyclooxygenase Inhibitor - don't want to use unless have to bc premature closure of ductus arteiosis and bleeding •reserved for extremely early labor b/c high risk of neonatal complications. (increased risk postpartum bleeding)

Menopause typically begins around age

50 years, but can begin as early as age 48 and as late as age 55.

•A nurse is teaching a client about terbutaline. Which of the following statements by the client indicates understanding of the teaching? A."This medication will stop my contractions." B."This medication will prevent vaginal bleeding." C."This medication will promote blood flow to my baby." D."This medication will increase my prostaglandin production."

A

hydroxyprogesterone caproate

AE: injection-site rxn, hives, nausea, diarrhea, thromboembolism - rare Recognized as a hazardous drug - esp. for pregnant nurses

Finasteride [Proscar]

By decreasing DHT, promotes regression of prostate epithelial tissue and thereby decreases mechanical obstruction of the urethra

Known risks of EPT include

CHD, stroke, thromboembolic events, breast cancer, and dementia. ET appears to be safer than EPT but still can cause stroke, DVT, and other undesired effects.

For all postmenopausal women, regardless of age, ET increases the risk of

DVT and stroke. In addition, for women older than 60 years, ET increases the risk of MI and CHD.

Postpartum Hemorrhage more drugs

Ergot Alkaloids class Methylergonovine: •AE: Severe HTN - reserved for when unresponsive to other agents •Action: Constricts veins, arterioles •Fast - 60 sec IV Contraindicated: •Pregnancy •HTN

-relieve bothersome urinary symptoms -delay disease progression

goal of drug therapy for BPH

In the absence of estrogen, urogenital degeneration is inevitable. What can relieve these symptoms?

Hormone therapy, either oral or topical, can reduce symptoms.

women

group of people that Sildenafil [Viagra] is not approved for

Estrogens can affect various nonreproductive tissues.

Important among these are bone, blood vessels, and the heart, liver, and central nervous system (CNS).

primary (1) inhibiting ovulation secondary (1) thickening of the cervical mucus (2) alteration of the endometrium

MOA of Combination OCs

(1) inhibits follicular maturation and ovulation (2) thickens the cervical mucus (3) causes thinning of the endometrium

MOA of Depot medroxyprogesterone acetate (DMPA)

Prominent among these are vasomotor symptoms, sleep disturbances, urogenital atrophy, bone loss, and altered lipid metabolism.

Drugs for Cervical Ripening

Prostaglandins: DRUG: •Dinoprostone (Cervidil)- synthetic prostaglandin available in gel or vaginal insert •AE: uterine tachysystole, N/V/D, fever •Misoprostol (Cytotec) - more effective, cheaper, more convenient (off-label for this use) •AE: higher risk uterine tachysystole, delivery occurs faster than with dinoprostone

postpartum hommorhage is 2nd leading cause of maternal mortality behind preeclampsia

TRUE

Should any woman use HT?

The answer is "Yes"—provided the benefits for the individual outweigh the risks.

Estrogens and progestins are hormones with multiple actions.

They promote female maturation and help regulate the ongoing activity of the female reproductive organs. In addition, they affect bone mineralization and lipid metabolism.

nitrofurantoin and methenamine

Urinary Tract Antiseptics

Estrogens are classified by the U.S. Food and Drug Administration (FDA) as Pregnancy Risk Category

Menopausal HT appears to pose

a small risk of ovarian cancer. However, data on this risk are conflicting.

preeclampsia

abnormal condition associated with pregnancy, marked by high blood pressure, proteinuria, edema, and headache high risk of seizure

Vasomotor symptoms develop in

about 70% of postmenopausal women. Hormone therapy is the most effective way to suppress symptoms.

Estrogens, in the form of oral contraceptives, can help control

acne

(1) cause less local irritation (2) can't fall off (3) produce more consistent testosterone levels.

no!

are buccal tablets affected by eating or drinking?

Because the risks of HT are greater than previously appreciated, many women are

discontinuing treatment.

no!
