Topics To Be Discussed
 New information from the WHI
 The expanding range of treatments for
managing menopausal symptoms
– Which treatments are available to your patient?
 Practice Recommendations
– How can your patient use these treatments safely,
effectively, and conveniently?
NAMS Definitions

 ET
 EPT
 HT
 CC-EPT
 CS-EPT
Progesterone or progestin (P)
Estrogen (E) therapy

Let’s Get This
Out of the Way….
The WHI Re-analyzed
Background: HRT 1960-1980s
 Menopause seen as endocrine deficiency
requiring hormone replacement therapy
 1960s: successful oral contraceptive introduction
– “The Pill” freed women from fear of pregnancy
– HRT offered women freedom from fear of aging
 1972: Forever Feminine by Robert A. Wilson, MD
 1980s: Expanding uses of HRT
– Initially used to treat hot flashes, vaginal sxs
– Later uses…protection of bone and heart
Background: Late 1980s
 In 40 retrospective observational studies, both EPT and
ET reduced the risk of heart attack by 50%
– Most studies included women in their 50s
– Women were self-selected for hormone use (or not);
studies were subject to selection bias
 Conventional wisdom
– All women should use HT for heart protection,
unless there was a reason not to do so
– Women with CVD risk factors, especially previous
MI, stroke, HTN or diabetes, should use HT
Background:1990s
 1990: Wyeth requested that FDA add labeling to
HT products that included cardioprotection
 FDA insisted that RCTs be performed to prove
that HT improved CVD outcomes vs. placebo
 Two RCTs initiated to evaluate cardioprotection
– HERS: secondary prevention trial
– WHI: primary prevention trial
HERS Study: 1998
 Does EPT reduce MIs in women with CHD?
 2,763 women randomized to CC-EPT or placebo
– Entry: MI, CABG, balloon angioplasty, + angiogram
– Menopausal, intact uterus, 44-80 years of age
– Average follow up: 4.1 years
 Study findings
– EPT had no value in reduction of MIs or CHD deaths
»More deaths in year 1; neutral thru year 8
»Not seen in prior observational studies
– 3-fold increased risk of VTE events
Hulley, JAMA 1998:280:605
Women’s Health Initiative (WHI): 2002
 1993-2005: RCT with 17,000 women
 Postmenopausal women 50-79 years old
– 33%: 50-59 yrs old; 45%: 60-69 yo; 22% 70-79 yo
– Average age: 64 years old
 End points
– Primary prevention of MI and stroke
– Hip fracture, various cancers
 Treatment arms
– If uterus: CC-EPT (CEE+MPA) vs. placebo
– If no uterus: ET (CEE) vs. placebo

The 2004 Take Home Message
 HT does not protect women from heart
attacks over the long term
…and actually may increase the risk of
MI in the first year of HT use
 The rest is “specialty-specific” perception
of benefit and risk
Was the WHI designed to evaluate the
safety and efficacy of EPT in treating
menopausal changes?
The Women’s Health Initiative
 Was not a menopause study
 Was a drug study of the effect of hormones
on CVD, cancer, fractures, and memory in
older women (average 64 year old)
How Different Were WHI Findings
Compared to Earlier Studies?

Clinical Implications: Unified Hypothesis
 Mild cardioprotection
– Women in their early-mid 50s, who
– Initiate HT soon after menopause, with
– Few or no heart disease or stroke risk factors
– And who use estrogen-only regimens
 Increased heart disease risk
– Women in their mid-60s or later, who
– Initiate HT long after menopause, who have
– Heart disease or stroke risk factors
– And who use estrogen and progestin regimens

HT and Coronary Heart Disease
 ET/EPT not recommended as single or
primary indication for coronary
protection in women of any age
 Data do not currently support EPT
in secondary prevention of CHD
NAMS position statement. Menopause 2007.
HT and Stroke
 Both ET and EPT appear to increase the risk
of ischemic stroke in postmenopausal women
 No HT regimen should be used for the
primary or secondary prevention of stroke
 HT should be avoided for women who have
elevated baseline risk of stroke
NAMS position statement. Menopause 2007.
HT and Venous Thromboembolism
 Significant increase in VTE risk in




postmenopausal women using systemic HT
Risk increased with both EPT and ET
VTE risk appears during first 1-2 years after
therapy initiation and decreases over time
Transdermal 17ß-estradiol and oral therapies may
have different risk
Lower doses of oral estrogens may be safer than
higher doses
NAMS position statement. Menopause 2007.
EPT and Breast Cancer Risk
 Breast cancer risk increases with EPT use
beyond 5 years
 Increased absolute risk in WHI is viewed as
rare (4-6 additional invasive cancers/10,000
women/year when use EPT used for ≥ 5 yrs)
 Not clear whether risk differs between CC-EPT
and CS-EPT
NAMS position statement. Menopause 2007.
ET and Breast Cancer Risk (cont’d)
 Women in WHI’s ET arm had 8 fewer cases of
invasive breast cancer/10,000 women/yr of ET use
 Available evidence suggests ET for < 5 years has
little breast cancer risk impact
 Limited observational data suggest ET given
longer than 15 years may increase risk
NAMS position statement. Menopause 2007.

Therapeutic Interventions
Non-Hormonal
General Health Recommendations
 Exercise: aerobic + strength training
– Reduction in hot flashes in some women

»400-800 IU of vitamin D3
– Adults 50 and over need, per day
»1,200 mg of calcium*
»800-1,000 IU of vitamin D3
* In divided doses, preferably with meals

Choice of Estrogens
 Start low dose transdermal or oral estrogen
 If suboptimal response, modify by:
– Change the estrogen dose (upward)
– Change the estrogen preparation
– Change delivery systems (oral
transdermal)
– Consider an estrogen-androgen combination
 Injectable estrogen not recommended
– Dosage equivalencies are not known
– Estrogen cannot be discontinued easily
Route of Administration
 Non-oral routes of ET/EPT administration may
offer advantages and disadvantages vs oral routes,
but the long-term risk-benefit ratio has not been
demonstrated
 Possible lower risk of deep venous thrombosis
(DVT) with non-oral route
 Similar increased breast cancer risks with oral and
transdermal estrogens, per large observational study

“First Line” Use of
Transdermal Estrogen
 Underlying medical conditions
– History of DVT or PTE
– High triglyceride levels
– Gall bladder disease
 Need for “steady state” drug release
– Daily mood swings (especially while on oral HT)
– Migraine headaches
 Inability to use oral tablets
– Stomach upset due to oral estrogen intake
– Problems with taking a daily pill
Lower HT Doses
 Provide nearly equivalent vasomotor and genital
skin symptom relief and preservation of BMD
compared to standard doses
 Additional local ET may be required for
persistent vaginal symptoms
 Lower HT doses better tolerated and may have a
better risk-benefit ratio than standard doses
(cont’d)
NAMS position statement. Menopause 2007.
Lower HT Doses (cont’d)
 Lower-than-standard ET/EPT doses should be
considered, such as daily doses of
– 0.3 mg oral conjugated estrogens
– 0.25-0.5 mg oral micronized 17β-estradiol
– 0.025 mg transdermal 17β-estradiol patch
– or the equivalent
NAMS position statement. Menopause 2007.
Progestogen Indication
 Primary menopause-related indication is
endometrial protection from unopposed ET
 Adequate progestogen (as CC-EPT or CS-EPT)
recommended with intact uterus
 Progestogen not generally indicated with ET
post-hysterectomy

Off-Label EPT Uses
 Insufficient endometrial safety evidence to
recommend off-label use of
– Long-cycle progestogen (ie, P every 3-6 months
for 12-14 days)
– Vaginal administration of progesterone
– Levonorgestrel intrauterine system (Mirena)
– Low-dose estrogen without progestogen
 Close endometrial surveillance recommended with
these approaches
NAMS position statement. Menopause 2007.
Compounded Bioidentical
Hormones
“Then, suddenly, the Seven
Dwarfs of Menopause arrived at
my door without warning: Bitchy,
Sweaty, Sleepy, Bloated,
Forgetful, and All-DriedUp….What was it that sent those
wretched dwarfs packing?
Natural bioidentical hormones.”
Somers S. The Sexy Years: Discover the Hormone Connection:
The Secret to Fabulous Sex, Great Health, and Vitality for Women and Men.
Front Matter. 2004 Random House, Crown Publishing, NY.
Compounded Hormone Therapy
 The marketing of compounded hormonal therapy
– Only bioidentical hormones are used
– Combination of 2 or 3 estrogens is more “natural”
– Dosage is tailored to the individual
– More “pure” than commercial products
– Safer delivery systems (no dyes, etc)
 The reality
– The same hormones are used in commercial and
compounded 17b-E2 and progesterone
Sources of Exogenous Hormones
Compounded Hormone Therapy
Compounded hormones will probably work, but…
 Salivary hormone levels are not useful
 The value of adding E1 + E3 has not been evaluated
 Progesterone skin cream is not absorbed
 Compounded hormone doses are not standardized
 FDA-approved HT products will offer
– Bioidentical hormones
– Choice of delivery systems
– Formulary coverage/ lower out-of-pocket costs

Act 3
Practice Guidelines
How can your patient use these
treatments safely, effectively, and
conveniently?
Treatment of Hot Flashes
 If mild sxs, try exercise, black cohosh + phytoSERM
 Initiate low dose HT if
– Moderate or severe symptoms
– Non-hormonal treatments have failed
– No interest in non-hormonal therapy
 Titrate estrogen dosage upward if needed
 When estrogen can’t be used, offer
– SSRI or SNRI
– Gabapentin, clonidine, a-methyldopa,
– MPA or Megesterol (Megace)
 Attempt discontinuation after 1-2 years
Treatment of Sleep/ Irritability Sxs
 If mild symptoms
– Lifestyle change, black cohosh, phytoSERMs
 If severe symptoms or no response to above
– Low dose HT, then titrate upward
– If mood swings, transdermal E preferred
 Depression component, or no response to HT
– SNRI or SSRI
HT and Vaginal Atrophy
 When HT is considered solely for this
indication, local (not systemic) vaginal ET is
generally recommended
 Progestogen generally not indicated with lowdose, local vaginal ET
 Vaginal lubricants often improve vaginal
dryness and painful intercourse

Vaginal ET: Endometrial Surveillance?
 There are insufficient data to recommend annual
endometrial surveillance in asymptomatic women
using low-dose, local vaginal ET
 Closer surveillance may be required if a
woman is
– At high risk for endometrial cancer
– Using a greater dose of vaginal ET
– Having symptoms such as spotting,
breakthrough bleeding
NAMS position statement. Menopause 2007.
HT and Cognition
 Initiating EPT after age 65 not recommended for
primary prevention of dementia or cognitive
decline
 Insufficient evidence to support ET/EPT for
primary prevention of dementia when therapy is
initiated during perimenopause or early
postmenopause
 ET does not appear to convey direct benefit or
harm for treatment of Alzheimer’s disease
NAMS position statement. Menopause 2007.
HT and Cognition
 Many women experience worsening of short term
memory with onset of menopause
 9 RCTs and 8 cohort studies
– HT does not improve cognitive performance in
women without symptoms
– If symptoms, HT improved verbal memory,
reasoning, and motor speed tests
 Reasonable to provide HT to lessen cognitive
changes in symptomatic menopausal women
Hormone Therapy and
Fracture Prevention
Pros
 Good data on fracture prevention (mainly 2o prevention)
 Relatively lower cost than boisphosphonates
 Less concern of adverse effects with ET alone (vs EPT)
Cons
 Requires long term use and surveillance
 Post-menopausal bleeding can be troublesome
 Increased risk of breast cancer after 5 years of use
Utility
 Fracture prophylaxis if using HT for another indication
 Otherwise, consider bisphosphonates as first line
HT and “Quality of Life”
 RCTs and retrospective studies show that HT has no
effect on “quality of life” measures
 Many woman who wean from HT state that they “feel
worse”…even after 20 years after menopause!
 Conventional wisdom
– In women who “feel better on/ worse off” of HT,
continue low dose HT if few or no risk factors
– When (& how often) to re-attempt wean uncertain
– Don’t start HT for solely for improving QOL
Act 4
The Finale
Discontinuation of HT
 After 2 years, recommend a trial of HT discontinuation
 Is tapering from hormone therapy necessary?
– Grady D, Obstet Gynecol 2003;102:1233
– n= 377 who attempted discontinuation of HT
– 74% successfully stopped; 26% resumed
– 71% stopped abruptly; 29% tapered: equal success
 “Rebound” hot flashes occur in some women and can
last up to 3 months…many experts recommend a taper
 Taper hormone therapy over 8-12 weeks
– Reduce dose or extend intervals (every 2, then 3 days)
– Cut patches in half
If what I just said
sounded unusually
clear, then you
must have
misunderstood me
