Indications of estrogen use
- Prevention of pregnancy
- Menopausal hormone replacement
- Endometriosis
- Dysfunctional uterine bleeding
- Urogenital atrophy
- Infertility
- PCOS
Contraindications of Estrogen Use
- Liver disease - can worsen disease
- Hypercoagulable states - impact the clotting cascade and increases risk of DVT or PE
- Cancers with increased growth in response to estrogen - breast, ovarian, uterine, endometrial
- Strong risk factors for atherosclerosis - HTN, DM, High cholesterol, Strong Family Hx
MOA Estrogen
Modulates the pituitary secretion of LH and FSH
Side Effects Estrogen
Migraine headaches, water retention (abdominal bloating, weight gain), stimulation of reproductive organs (vaginal bleeding or spotting - growth of endometrial tissue), enlarged fibroids, breast tenderness, gallbladder disease (associated with long term use), nausea, thrombosis, skin rashes, increased triglycerides
In post-menopausal woman what do you need to administer with estrogen and why?
Progesterone. Estrogen stimulates endometrial growth and can stimulate cancers of reproductive tissues.
Only applies if the patient has a uterus. If patient has hysterectomy, then can just give estrogen only.
What role does estrogen play with blood clotting and delivery?
Right after birth, estrogen is high and aids in preventing hemorrhage after birth. However, it increases her risk of DVT and PE in the long term recovery process of delivery.
Indications of Progestins
- prevention of pregnancy
- menopausal HTR
- decrease endometrial hyperplasia
- treatment of secondary amenorrhea
- Emergency contraception: high dose only
- Dysfunctional uterine bleeding - aids in excessive bleeding for pt
Contraindications Progestins
- Risks for DVT and PE (less than estrogen though)
- Unexplained vaginal bleeding
- Breast cancer
- Active liver disease
- Conditions of concern for hypoestrogenic effects and reduce HDL levels, can increase CVD risk - HTN with vascular disease, ischemic heart disease, Hx stroke
- DM for over 20 years or with neuropathy, retinopathy, neuropathy, or vascular disease
MOA progestin
inhibits the pituitary GnRH, prevents follicular maturation, transforms proliferative endometrium into secretory endometrium, Inhibits spontaneous uterine contractions
What generation of progestins is most androgenic?
second generation
The more androgenic progestin, what happens for the patient?
creates more testosterone like side effects
What progestin is the most androgenic?
Levonorgesterol
Side Effects Progestins
- Androgenic activity - acne, hirsutism, increased LDL, increased insulin resistance
- DVT
- Vaginal bleeding - common with progesterone only OC
- Weight gain
What patient education do you need to include with progesterone only OC?
Must take it at the same time every day (at least within the same 30-60 mins)
Drospirenone (a progestin) is structurally similar to what medication? And who can this medication be good for?
