Pharm Reproduction Exam 2 Flashcards
Menopause and non hormonal therapy
The best studied agents with positive results include
SSRI SNRI Anti epileptics Clonidine Oxybutynin Centrally acting drugs
MHT
Menopausal hormone therapy (MHT)
Broad term that describes unopposed estrogen use for women who have undergone hysterectomy,
and
combined estrogen-progestintherapy (EPT) for women with an intact uterus who need a progestin to prevent estrogen-associated endometrial hyperplasia.
The primary goal of MHT is to?
Relieve vasomotor symptoms (hot flashes).
Other symptoms associated with perimenopause and menopause that respond to estrogen include
sleep disturbances, depression/anxiety, and, in some cases, joint aches and pains.
Standard recommendations of use of MHT
3 to 5 years
Extended use can be done in severe or persistent cases
Which types of estrogen are good for hot flashes
All types of estrogen are equal for hot flashes
17 beta estradiol is preferred
structurally identical to estrogon secreted by ovary
Estradiol indications
Estrace (estrogen)
Moderate-to-severe vasomotor symptoms of menopause. Atrophic vaginitis. Hypoestrogenism. Osteoporosis prevention.
Estradiol
Contraindications
warnings
Contra Breast or estrogen dependent cancer Thromboembolic disorders Undiagnosed abnormal genital bleeding Preg CAT X
Warnings
Increased risk of endometrial carcinoma or hyperplasia in women with intact uterus (adding progestin is essential).
Increased risk of cardiovascular events (eg, MI, stroke, VTE); discontinue if occurs. Manage risk factors for cardiovascular disease and venous thromboembolism appropriately.

2 types of dysmenorrhea
Primary and secondary
Primary dysmenorrhea

Improves with age
Common and normal
Secondary Dysmenorrhea

Uterine fibroids
PID
Begins 1-2 days before period
Lasts for over 3 days
Lower abdomen (radiate to legs and back)
Gets worse with age
Indicates reproductive tract disease
Which type of dysmenorrhea gets better with age
Primary dysmenorrhea
Dysmenorrhea treatment goal
Relief of pain
Should allow women to perform usual activities
Primary dysmenorrhea can be treated empirically
Dysmenorrhea resistant to treatment
NSAIDS
Hormonal contraceptives’
are mainstay of treatment
Dysmenorrhea resistant to treatment
NSAIDS

Endometrial cancer
Affects postmenopausal women almost exclusively
Endometrial hyperplasia drug causes
Tamoxifen
Prevention for ovarian cancer
OCP (oral contraceptive pills)
Decreases risk of developing ovarian cancer
especially in young women who have used it for several years
If used for over 5 years, 50% less chance of ovarian cancer
