testosterone
responsible for normal development and maintenance of primary and secondary male sex characteristics
development of bone and muscle tissue
- inhibition of protein catabolism (metabolic breakdown)
- retention of carious electrolytes (nitrogen, phosphorus, potassium, and sodium)
- stimulates the production of blood cells
ANDROGEN'S
-anabolic steroids
anabolic activity: synthesis of tissue and increasing tissue formation
- schedule 3, great potential for tissue by athletes
- oxymetholone (anadrol-50)
- oxandrolone (oxandrin)
- nandrolone (deca-durabolin)
androgens
-anabolic steroids: approved indications
adjunctive therapy to promote weight gain after extensive surgery, trauma, chronic diseases, anemia, hereditary angioedema, and metastatic breast cancer
androgens
-anabolic steroids: great potential for misuse
- serious consequences: sterility, cardiovascular diseases, and liver cancer
- misuse of these drugs can lead to psychological or physical dependence or both
androgens
-danazol (danocrine)
- synthetic androgen is danazol (danocrine)
- use: treatment or hereditary angioedema, and, in women, endometriosis and fibrocystic breast disease
androgens
-mechanism of action
- effects are similar to the body's endogenous androgens
- stimulate increased synthesis of body proteins, aiding in the formation of muscular and skeletal proteins
- enhanced erythropoiesis production by the kidneys
- stimulate normal growth and development of the male sex organs (primary sex characteristics)
alpha-adrenergic blockers
- used for symptomatic relief of obstruction caused by BPH
- doxazosin (cardura)
- tamsulosin (flomax)
- terazosin (hytrin)
- alfuzosin (uroxatral)
- silodosin (rapaflo)
drug therapy for benign prostatic hyperplasia
- alpha-1 adrenergic blocking agents alfuzosin and tamsulosin are used to relax smooth muscle of bladder and prostate.
- other alpha-1 adrenergic blocking agents are also used to treat hypertension
drug class: alpha-1 adrenergic blocking agents
BPH symptoms are similar to prostate cancer
action: block alpha-1 receptors on the prostate gland, causing muscle relaxation, allowing greater urinary outflow
alpha-1 - adrenergic blockers
- these drugs have clinical effects of prostate shrinkage immediately.
- 5-alpha reductase inhibitors may take up to 6 months of continual therapy for clinical effects of prostate shrinkage
antiandrogen agents
drug: dutasteride (avodart)
actions: inhibits enzyme 5-alpha reductase, reduce DHT levels
uses:treatment of symptoms of BPH, reduces risks of urinary retention, minimizes need surgery for BPH
Hormone replacement therapy (HRT)
Not recommended for women with histories of endometrial cancer
conjugated estrogens(Premarin)
MOST COMMON
Estrogen: contraindications
undiagnosed abnormal vaginal bleeding
- anything with estrogen always chose answer with bleeding and blood clots
Amenorrhea
absence of period
estrogen: interactions
decrease the activity of the oral anticoagulants
- smoking should be avoided-decrease effects of the estrogen and increase risk of thrombosis (blood clots)
contraceptive drugs: MOA
Prevent ovulation by inhibiting the release of gonadotropins and increasing uterine mucus viscosity resulting in decreased sperm movement and possible inhibition of implantation of fertilized egg
oral contraceptive's
prior to starting; pregnancy test needs to be preformed and negative
minipill
contains ONLY progestion
minipill-
what to teach your patient regarding this medication
if you miss a dose, take medication as soon as you notice
contraceptive drugs - pregnancy
known high risk for thromboembolic events
progestin's indication
- hormonal imbalance, fibroids, uterine cancer.
- prevention of threatened miscarriage
adverse effects of progestions
liver dysfunction, thrombophlebitis, thromboembolic disorders, such as PE
Megestrol - megace
can cause appetite stimulation and weight Gain
osteoporosis
the most common bone disease
female, postmenopausal women, hypogonadism, low body weight (slender body build), history of parental hip fracture, ethnic background (European or asian descent) have higher risk for osteoporosis
(T/F)
true
bisphosphonate
builders, can reverse lost bone mass and reduce fracture risk
alendronate (fosamax)
given once a week and has to sit up for at least 30 minutes and has to drink 8oz of water after
calcitonin (calcinar)
if patient has a salmon allergy; should NOT take
teriparatid (forteo)
stimulates bone formation
denosumab (prolia)
prevents bone resorption
raloxifene
decreases the effects of warfarin (anti-coagulant)
bisphosphonates
drug allergy, hypocalcemia, esophageal dysfunction, and the inability to sit or stand upright for at least 30 minutes after taking the medication
SERMS-
adverse effects
hot flashes, leg cramps
fertility drug: clomiphene
maturation of ovarian follicles is stimulated, leading to ovulation and increased chance of conception
menotropins
may also be given to men to stimulate spermatogenesis
diplopia
doubled vision
uterine stimulate
given to promote labor
- postpartum use: reduce the risk of postpartum hemorrhage, induction of therapeutic abortion
oxytocin (synthetic form)
used to induce labor or near full term gestation and to enhance labor when contractions are weak or ineffective
prostaglandins
used to induce labor by softening the cervix and enhancing uterine muscle tone
cytotec
think cervix
ergot alkaloids
increase force and frequency of uterine contractions
uterine stimulants (oxytocin)
- dont leave patient unattended, use IV pump
- monitor uterine contractions, fetal heart rate and rhythm, observe for fetal distress.
- overdose may cause hyper stimulation of the uterus
