1

what is the most potent form of endogenous estrogen in women?

estradiol

2

how is estrogen transported in the blood?

bound to albumin and sex binding hormone (they are later broken down by the liver to inactive compounds and excreted in urine)

3

what is the most important therapeutic benefit of HRT?

estrogen decreases resorption of bone and thus blunts the process of osteoporosis.

- it can also assist with sleep quality in post-menopausal women

4

Increased risks with HRT?

Stroke and blood clots

decreased risk of fractures

5

are bio-identical hormones considered synthetic?

yes, they are. They just look similar to the ones produced by the body.

6

What is the hormone ratio of BiEst?

80:20 ratio of estriol (E3) to estradiol (E2)

7

What is the hormone ratio of TriEst?

most commonly found in a ratio of 80: 10: 10, estriol (E3), estradiol (E2) and estrone (E1).

8

What is the source of premarin

obtained from the urine of pregnant mares is a preparation of conjugated estrogens – estrone and equillin.

9

when is premarin indicated?

for prevention and treatment of osteoporosis and of post-menopausal symptoms such as hot flashes, vaginal dryness and itching.

can be used in women who has not undergone hysterectomy. Do not use in pregnant women.

10

MOA of premarin?

Alters gene transcription.

11

Side effects of premarin?

breast pain, increased breast size, palpitations, fever, hives, hoarseness, joint pain, stiffness or swelling, rash, redness of skin, shortness of breath, wheezing, edema and weight gain.....etc.

12

What pregnancy category are conjugated estrogens/Premarin?

Category X

also CI in prior hx of DVT or breast/ovarian/urine cancer

what class is Medroxyprogesterone/Provera?

synthetic variant of progesterone (progestin)

14

when is provera indicated?

Contraceptive, hormone replacement therapy, dysfunctional uterine bleeding and treatment of endometriosis.

15

MOA of provera?

alters gene transcription

16

to prevent the development of endometrial hyperplasia and endometrial cancer.

17

What is the Depo form of provera?

I.M.

18

what are the functions of estrogen and progestin in oral contraceptives?

alteration of gene transcription

23

What is the administration route for testosterone

injectable, PO, Sub-lingual, transdermal patches, gels, creams

24

What is the deal with anabolic steroids

They are synthetic derivatives of testosterone that have far stronger anabolic effects than androgenic effects

25

What class is Leuprolide (lupron)

Anti-androgenic hormone and anti estrogenic hormone

26

What are the indications for leuprolide (lupron)

Prostatic cancer, precocious puberty, endometriosis and uterine fibroids, as well as being part of some protocols of I.V.F.

27

What drug class is finasteride

Anti-androgen

28

What is the MOA of finasteride

Limits conversion of T to DHT by inhibiting 5-alpha-reductase II

29

What are warnings that come with using finasteride
