Objectives
Discuss the current recommendations for
the
use of hormone replacement therapy
Compare and contrast the various dosage
forms available for hormone replacement
therapy
Facts and Figures
35 million women are >50 years of age
50-85% of menopausal women will
experience symptoms of estrogen
deficiency
25% of these women will have significant
distress from these symptoms

Goals of Therapy
Reduce symptoms resulting from estrogen
imbalance
Treat urogenital atrophy and vaginal dryness
Minimize risk of disorders that may be more
frequent during hormone replacement therapy

Current Recommendations
FDA Indications for HRT
Treatment of moderate to severe vasomotor
symptoms associated with menopause
Treatment of moderate to severe symptoms of
vulvar and vaginal atrophy
Prevention of postmenopausal osteoporosis
Current Recommendations
Decision to use HRT should be based on
patient specific risk vs benefit
Use the lowest dose to control symptoms
for the shortest duration
Reevaluate dose as patient ages
Use progestogen with estrogen in women
with a uterus
HRT should not be used to prevent
chronic diseases
Ann Intern Med. 2005;142:855-860.
Endocrine Practice Vol 12 No. 3 May/June 2006
Transdermal
Advantages
Avoids first-past effect
Avoids induction of triglyceride production
Does not increase production of angiotensinogen
May reduce thromboembolic risk associated with
oral estrogen
Transdermal
Transdermal Patches
17-estradiol (e.g. Menostar
, Vivelle Dot
,
Estraderm
)
Doses 0.014 mcg to 0.1 mcg
17-estradiol + Norethindrone acetate
(CombiPatch
)
17-estradiol + levonorgestrel acetate
(Climara Pro
)
Once or twice weekly application
Transdermal Gels
All products are once a day
Apply at the same time each day
Apply after bath, shower, sauna use
Wash hands after application
No currently available products with a
progestogen
Women with a uterus still require a progestogen
All Gels and spray are not approved for
osteoporosis prevention or treatment

Indicated for treatment of moderate to
severe vasomotor symptoms/ vulvar and
vaginal atrophy
May cause hyperkalemia
Only available in 1mg/0.5mg
Cannot provide low dose estrogen with this
product
Angeliq Package Insert Bayer 2007
Vaginal Products
Local therapy is effective in treating vaginal
therapy
Cochrane Review suggests all vaginal estrogen
products are equally effective
Progestogen therapy is not needed for local
therapy
However systemic absorption does occur
Conjugated estrogens creams may have higher
incidence of adverse effect compared to the ring
or vaginal tablet delivery

Systematic Reviews 2006, Issue 4. Art. No.: CD001500.

Androgens
In 2003 FDA question the effectiveness of
conjugated estrogen/ methyltestosterone
products
Products never have been approved by FDA
Controversial when androgens should be
utilized
Difficult to determine true androgen deficiency
Endocrine Practice Vol 12 No. 3 May/June 2006
Federal Register: April 14, 2003 (Volume 68, Number 71)
Androgens
Androgen insufficiency
Loss of Libido
Decreased sexual motivation, enjoyment
Insomnia, depression, poor concentration
Adequate estrogen status
Very low free-testosterone levels
Testosterone typically does not decline in
menopause
Produced by ovaries
Endocrine Practice Vol 12 No. 3 May/June 2006
Androgens
Possible applications (more studies
needed)
Post-menopausal women with androgen
insufficiency despite adequate estrogen
replacement
Women who have undergone bilateral
oophorectomy and are on estrogen therapy
Generally not recommended
