  • low-dose (preferred dose: 0.3 mg Premarin®/25 µg Estradot® patch, can increase if necessary)
  • progestin
  • given in combination with estrogen for women with an intact uterus to prevent development of endometrial hyperplasia/cancer
19
Q

Describe this HRT regimen: Unopposed Estrogen

  • Estrogen dose
  • Progestin dose
  • Notes
A

20
Q

Describe this HRT regimen: Standard-Dose

  • Estrogen dose
  • Progestin dose
  • Notes
A
  • Estrogen dose: CEE 0.625 mg PO OD
  • Progestin dose: MPA 2.5 mg PO OD, or micronized progesterone 100 mg PO OD
  • Notes:
    • Withdrawal bleeding may occur in a spotty, unpredictable manner
    • Usually abates after 6-8 mo due to endometrial atrophy
    • Once patient has become amenorrheic on HRT, significant subsequent bleeding episodes require evaluation (endometrial biopsy)
21
Q

Describe this HRT regimen: Standard-Dose Cyclic

  • Estrogen dose
  • Progestin dose
  • Notes
A
  • Estrogen dose: CEE 0.625 mg PO OD
  • Progestin dose: MPA 5-10 mg PO days 1-14 only, or micronized progesterone 200 mg PO OD days 1-14 only
  • Notes:
    • Bleeding occurs monthly after day 14 of progestin (can continue for years)
    • PMS-like symptoms (breast tenderness, fluid retention, headache, nausea) are more prominent with cyclic HRT
22
Q

Describe this HRT regimen: Pulsatile

  • Estrogen dose
  • Progestin dose
  • Notes
A
  • Estrogen dose: CEE 0.625 mg PO OD
  • Progestin dose: MPA low-dose
  • Notes: 3 d on, 3 d off
23
Q

Describe this HRT regimen: Transdermal

  • Estrogen dose
  • Progestin dose
  • Notes
A
  • Estrogen dose:
    • Estroderm®-Estradiol 0.05 mg/d or 0.1 mg/d
    • Estalis®-Estradiol 140 µg/d or 250 µg/d

    • Estroderm®-MPA 2.5 mg PO OD
    • Estalis®-NEA 50 µg/d
  • Notes:
    • Use patch twice weekly
    • Can use oral progestins (Estroderm®)
    • Combined patches available (Estalis®)
24
Q

Describe this HRT regimen: Topical

  • Estrogen dose
  • Progestin dose
  • Notes
A
  • Estrogen dose:
    • Estrace® 2-4 g/d x 1-2 wk, 1 g/d maintenance
    • Premarin® 0.5-2 g/d for 21 d then off 7 d for vaginal atrophy, 0.5 g/d for 21 d then off 7 d or twice/wk for dyspareunia
    • Estragyn® 2-4 g/d
  • Progestin dose: Crinone® 4% or 8% (45 or 90 mg applicator)
  • Notes:
    • If simultaneously taking oral estrogen tablet, may need to adjust dosing
    • If intact uterus, also take progesterone
25
Q

Name Side Effects of HRT (5)

A
  • abnormal uterine bleeding
  • mastodynia: breast tenderness and swelling

  • pre-existing uncontrolled HTN
  • uterine fibroids and endometriosis
  • familial hyperlipidemias
  • migraine headaches
  • family history of estrogen-dependent cancer
  • chronic thrombophlebitis
  • DM (with vascular disease)
  • gallbladder disease, hypertriglyceridemia, impaired liver function (consider transdermal estrogen)
  • fibrocystic disease of the breasts
28
Q

Describe: Women’s Health Initiative (6)

A
  • launched in 1991
  • two non-randomized studies investigating health risks and benefits of HRT in healthy postmenopausal women 50-79 yr old
    • continuous combined HRT (CEE 0.625 mg + MPA 2.5 mg OD) in 16,608 women with an intact uterus
    • estrogen-alone (CEE 0.625 mg) in 10,739 women with a previous hysterectomy
  • both arms of the trial were stopped early because of evidence of increased risk of breast cancer, stroke, PE, and CHD in the combined HRT arm, and increased risk of stroke with no CHD benefits in the estrogen-alone arm
  • the apparent increase in CHD was in disagreement with results of previous observational trial
  • results of the WHI study have since been challenged and revision of how CHD was diagnosed led to loss of statistical significance of the results
  • benefits and risks reported as number of cases per 10,000 women each year
29
Q

Name absolute contraindications to HRT (4)

A

ABCD

  • Acute liver disease
  • Undiagnosed vaginal Bleeding
  • Cancer (breast/uterine), Cardiovascular disease
  • DVT (thromboembolic disease)
30
Q

Name benefits of HRT (3)

A
  • Vasomotor Symptoms: less frequent and severe with use of either combined or estrogen alone HRT
  • Osteoporosis: 5 fewer cases of hip fractures and 47 fewer cases of all fractures with combined HRT; 6 fewer cases of hip fractures with estrogen alone
  • Colon Cancer: 6 fewer cases with combined HRT (WHI); one additional case with estrogen alone
31
Q

Name risks of HRT (5)

A
  • Stroke: 8 additional cases with combined HRT and 12 additional cases for estrogen alone (WHI)
  • DVT/PE: 18 additional cases with combined HRT and 9 additional cases for estrogen-alone (WHI)
  • CHD: 7 additional MIs with combined HRT (WHI); secondary analysis suggests greater absolute risk for women aged >70 yr and for women who start HRT >10 yr post-menopause
  • Breast Cancer: 8 additional cases with combined HRT (WHI); risk only increased after >5 yr of combined HRT use; no increased risk for estrogen alone
  • Dementia and Mild Cognitive Impairment: 50% greater risk of developing dementia in women taking estrogen alone after age 65; risk is greater for women taking combined HRT; risk of developing dementia was reduced for women taking HRT before age 65
