    Study Notes

    Female Reproductive System

    • Consists of ovaries, fallopian tubes, uterus, vagina, & vulva.
    • Development and maintenance controlled by pituitary gonadotropin hormones and female sex hormones: estrogens and progestins

    Female Sex Hormones

    • Estrogens:
      • Three major types: estradiol, estrone, estriol.
      • Synthesized from cholesterol in ovarian follicles.
      • Responsible for development & maintenance of female reproductive system and secondary sex characteristics.
    • Progestins:
      • Synthetic version of progesterone.
      • Responsible for endometrial tissue proliferation, increased basal body temperature, thickening of vaginal mucosa, relaxation of uterine smooth muscle, and alteration of menstrual blood flow.

    Pituitary Gonadotropin Hormones

    • Follicle-stimulating hormone (FSH) and Luteinizing hormone (LH).
    • Regulate menstrual cycle through hormonal communication between pituitary gland and ovaries.

    Estrogenic Drugs

    • Used when there is underproduction of endogenous estrogens.
    • Two types: steroidal and nonsteroidal.
    • Examples: conjugated estrogens (Premarin®), estradiol transdermal (Climara®, Divigel®), estradiol vaginal ring (Estring®).
    • Mechanism of action: Bind to intracellular estrogen receptors, stimulating synthesis of DNA, RNA, and proteins.
    • Indications: Treatment or prevention of estrogen deficiency disorders, oral contraception, hysterectomy, uterine bleeding, vasomotor spasms of menopause, osteoporosis, breast cancer, ovarian failure, cross-gender hormone treatment, severe acne.

    Progestational Drugs

    • Examples: levonorgestrel (Min-Ovral®), medroxyprogesterone (Provera®, Depo-Provera®), megestrol (Megace®), norethindrone acetate (Norlutate®), progesterone (Prometrium®).
    • Indications: Treatment of functional uterine bleeding, primary & secondary amenorrhea, cancers, endometriosis.
    • Contraindications: Similar to estrogens, including drug allergy, estrogen-dependent cancer, undiagnosed abnormal vaginal bleeding, pregnancy, active thromboembolic disorder.

    Contraceptive Drugs

    • Prevent pregnancy through inhibition of ovulation and increased uterine mucus viscosity.
    • Types: Oral contraceptive medications, IUD, long-acting injectable medroxyprogesterone, transdermal contraceptive patch, contraceptive vaginal ring.
    • Indications: Primarily for preventing pregnancy, but also used for treatment of endometriosis, hypermenorrhea, amenorrhea.

    Osteoporosis

    • Low bone density and deterioration of bone tissue, increasing fracture risk.
    • Primarily affects women.
    • Risk factors: gender, age, fragility fracture over 40, history of hip or vertebral fracture, medical conditions, smoking, alcohol use, menopause before 45, low estrogen levels, weight under 60 kg.
    • Treatment options: bisphosphonates, SERMs, hormones, denosumab.

    Uterine Stimulants

    • Medications used to increase uterine contractions to promote labor progression.
    • Used to promote labor, reduce postpartum hemorrhage, promote uterine shrinkage.
    • Types: oxytocin, prostaglandins, ergot derivatives.
    • Contraindications: drug allergy, pelvic inflammatory disease, placenta previa, uterine prolapse.

    Tocolytics

    • Inhibit labor and maintain pregnancy.
    • Used to delay delivery to allow fetal lung development (glucocorticoid administration).
    • Used to stop premature labor (20th to 37th week of gestation).
    • Nonpharmacological measures: bed rest, sedation, hydration.

    Men's Reproductive System

    • Consists of testes, seminiferous tubules, and androgens (testosterone being the most well-known).

    Androgens

    • Testosterone: responsible for development and maintenance of male sex characteristics, bone and muscle tissue development, inhibition of protein catabolism, electrolyte retention, and red blood cell production.
    • Anabolic steroids: chemical derivatives of testosterone with high anabolic activity, often misused by athletes. Examples: oxandrolone, nandrolone.
    • Mechanism of action: stimulate growth and development of male sex organs, maintain secondary sex characteristics, increase protein synthesis, enhance red blood cell production.

    Prostate Drugs: Androgen Inhibitors

    • Block the effects of androgens, inhibiting growth.
    • Examples: finasteride (Proscar®), dutasteride.
    • Used for treating symptomatic BPH, preventing thinning hair in male pattern baldness.

    Prostate Drugs: α1-Adrenergic Blockers

    • Used for symptomatic relief of obstruction caused by BPH.
    • Examples: tamsulosin (Flomax®), doxazosin (Cardura®), terazosin (Hytrin®).
    • Provide immediate clinical effects of prostate shrinkage compared to 5-α reductase inhibitors.

    Drugs to Treat Erectile Dysfunction: Phosphodiesterase Inhibitors

    • Used in the treatment of erectile dysfunction (ED).
    • Examples: sildenafil (Viagra®), tadalafil (Cialis®).
    • Mechanism of action: cause relaxation of smooth muscle in the penis, permitting blood inflow for erection.
    • If erection lasts longer than 4 hours, seek medical attention immediately.

    Nursing Implications: Women’s Health Drugs

    • Assess baseline vital signs, weight, blood glucose levels, renal and liver function, and smoking history.
    • Assess medication history, contraindications, and potential pregnancy.
    • Follow specific administration guidelines for uterine relaxants or stimulants.
    • Monitor patient's vital signs and fetal condition.
    • For estrogens and progestins, use the lowest effective dose for the shortest time possible.
    • Educate patients on correct self-administration and report any weight gain.
    • Advise patients to complete annual follow-up examinations.

    Nursing Implications: Men’s Health Drugs

    • Assess complete history including medication history, urinary elimination problems, and potential contraindications.
    • Obtain baseline vital signs, weight, height, serum electrolyte levels, and PSA if relevant to prostate concerns.
    • Assess renal and liver function and current medications for potential interactions.
    • Follow specific administration guidelines and educate patients on proper administration techniques.
    • Monitor for therapeutic responses.
    • For men with erectile dysfunction, seek immediate medical attention if erection lasts longer than 4 hours.### Diuretics
    • Carbonic anhydrase inhibitors, loop diuretics, osmotic diuretics, potassium-sparing diuretics, and thiazide/thiazide-like diuretics are five main types of diuretics.
    • Loop diuretics are more potent than thiazides, potassium-sparing, and combination diuretics
    • Furosemide is more likely used for edema associated with heart failure than for routine management of HTN
    • Hypotension and electrolyte disturbances are common concerns with diuretic use.
    • Caution is advised when using diuretics in patients who are older, have chronic illness, and/or with renal or hepatic compromise.

    Fluid Volume and Administration

    • Total body water is primarily in the intracellular space.
    • The extracellular space is primarily divided across the interstitial space and the intravascular space (plasma).
    • Extracellular water distribution is a balance between colloid osmotic pressure and intravascular hydrostatic pressure.
    • Normal saline is an inexpensive means of increasing extracellular volume and does not typically interact with medications.
    • Colloids are indicated for increasing intravascular volume with a reduced risk of shifting to the interstitial space.
    • Hypertonic solutions, potassium solutions, and various blood products are more likely to be irritating to veins.

    Electrolytes and Blood Products

    • Na and K imbalances are the most commonly treated electrolyte imbalances.
    • Blood products must be given only with 0.9% sodium chloride.

    Contraceptives, Uterine Stimulants and Relaxants

    • The most commonly used form of oral contraceptives is a combination of estrogens and progestins.
    • Uterine stimulants include oxytocin, prostaglandins, and ergot derivatives.
    • Uterine relaxants are used to stop preterm labor.

    Osteoporosis Treatments

    • Drugs used to treat osteoporosis include bisphosphonates, selective estrogen receptor modulators, calcitonin, and denosumab.
    • Bisphosphonates are the commonly prescribed medications for the treatment of osteoporosis.

    Men's Health Drugs

    • The most commonly used men's health drugs are finasteride (BPH), sildenafil (ED), and testosterone.
    • Nitrates are contraindicated if patients are taking sildenafil, tadalafil, vardenafil, or alprostadil.
    • Oral testosterone use is uncommon, typically topical or parenteral.
