HRT Compounding & Bioidentical Hormones 1 — Questions and Answers
Question 1: What distinguishes bioidentical hormones from synthetic hormones?
- They have the same molecular structure as hormones produced by the human body (Correct answer)
- They are derived exclusively from plant sources without laboratory modification
- They are more potent than synthetic hormone preparations
- They are only available through FDA-approved commercial products
Correct answer: They have the same molecular structure as hormones produced by the human body
Bioidentical hormones are chemically identical in molecular structure to the hormones naturally produced by the human body, unlike synthetic hormones which may differ structurally.
Question 2: Which U.S. regulatory bodies share oversight of compounding pharmacies?
- The FDA and individual state boards of pharmacy (Correct answer)
- The DEA and the CDC jointly
- CMS (Centers for Medicare & Medicaid Services) exclusively
- The FTC and state attorney general offices
Correct answer: The FDA and individual state boards of pharmacy
Compounding pharmacies are regulated by both the FDA under federal law and individual state boards of pharmacy under state law, creating a dual oversight system.
Question 3: What is the primary advantage most often cited for compounded bioidentical HRT over standard commercial preparations?
- Customizable dosing tailored to individual patient needs (Correct answer)
- Lower cost guaranteed by federal compounding regulations
- Complete absence of side effects compared to commercial HRT
- Longer shelf life than commercially manufactured products
Correct answer: Customizable dosing tailored to individual patient needs
The principal advantage of compounded BHRT is the ability to customize hormone doses, combinations, and delivery forms to meet each patient's specific requirements.
Question 4: Compounded estriol vaginal cream is commonly used for which condition?
- Hot flashes and night sweats
- Vaginal atrophy with localized estrogen effect (Correct answer)
- Osteoporosis prevention requiring systemic exposure
- Male hypogonadism hormone replacement
Correct answer: Vaginal atrophy with localized estrogen effect
Compounded estriol vaginal cream targets vaginal atrophy by delivering estrogen locally to vaginal tissues with minimal systemic absorption.
Question 5: What does the compounded formulation 'Bi-Est' contain?
- A combination of estradiol (E2) and estriol (E3) (Correct answer)
- A combination of estradiol (E2) and estrone (E1)
- A combination of two synthetic progestins
- A combination of testosterone and DHEA
Correct answer: A combination of estradiol (E2) and estriol (E3)
Bi-Est is a compounded formulation combining two bioidentical estrogens—estradiol (E2) and estriol (E3)—typically in a ratio such as 20:80 or 80:20.
Question 6: What does the compounded formulation 'Tri-Est' contain?
- Estrone (E1), estradiol (E2), and estriol (E3) (Correct answer)
- Three different synthetic progestins
- Testosterone, DHEA, and pregnenolone
- Estradiol, progesterone, and testosterone
Correct answer: Estrone (E1), estradiol (E2), and estriol (E3)
Tri-Est combines all three primary endogenous estrogens: estrone (E1), estradiol (E2), and estriol (E3) in a single compounded preparation.
Question 7: From which plant precursors are most bioidentical hormones derived before laboratory conversion?
- Wild yam and soy (Correct answer)
- Aloe vera and chamomile
- Conjugated equine sources only
- Synthetic petrochemical compounds
Correct answer: Wild yam and soy
Most bioidentical hormones are derived from diosgenin found in wild yam and phytoestrogens from soy, which are then chemically converted in the laboratory to the identical molecular structure of human hormones.
