Hormone Replacement Therapy Flashcards
Peak occurences and ethnic disparity for vasomotor symptoms in menopause
- late perimenopause and early postmenopause
- - greater severity and frequency in African Americans
Non pharmacologic approaches to post menopausal management
- avoid smoking
- moderate alcohol consumption
- dress in layers/cool drinks/maintain low ambient temp
- aerobic exercise (indirect effect on mood/perceived stress/body image)
- paced respiration/clinical hypnosis/behavioral therapy
17-Beta-Estradiol, Ethinyl Estradiol, Conjugated Estrogen
Oral estrogen replacement therapies,
Bazeedoxifene (conjugated estrogen)
combination estrogen + SERM (selective estrogen receptor modifier) – acts as agonist to some estrogen receptors and antagonist to others (uterus),
reducing endometrial outgrowth!
Transdermal estrogen advantages
17-Beta-Estradiol patch/gel/spray/emulsion
– avoids 1st pass metabolism = decreases prothrombotic hemostatic changes
Targets for Prothrombotic hemostatic changes instigated by oral estradiol
- Factor IX
- Protein C Resistance
- TPA (tissue plasminogen activator)
How long after initiating hormone replacement will patients feel symptom relief?
1 month
Most effective treatment for vasomotor symptoms and urogenital atrophy?
estrogen + progesterone
3 mechanisms of administration for estrogen, 2 for progestogen
Estrogen:
Oral,
transdermal (17B-estradiol patch/gel/spray/emulsion)
Vaginal (17B-estradiol cream/tablet/emulsion)
Progestogen:
Oral
Transdermal
Oral progesterones? Transdermal?
oral: Medroxyprgosesterone acetate, Norethindrone acetate, draspirenone, Micronized progesterone
transdermal: norethindrone acetate, levonorgestril
most common dose related adverse effects?
breast tenderness, uterine bleeding, (+ HAs, vomiting, weight change, rash/pruritis, cholecystitis)
consequences of stopping MHT?
- 50% chance of VMS recurring
- bone resorption accelerates
- vulvovaginal atrophy
- risks/benefits return relatively rapidly to baseline w/ exception of breast cancer risk which persists a few years
Non hormonal medications for VMS? + common side effects?
Paroxetine, Fluoxetine, Escitalopram – nausea, HA, insomnia, sexual dysfunction
Venlafaxine — nausea, vomit, dry mouth, anorexia, sexual dysfunction
Clonidine – dry mouth, insomnia, drowsiness, skin reaction with transdermal patch
Gabapentin – dizziness, unsteadiness, drowsiness
Clonidine MOA in VMS
lowers peripheral vascular reactivity, raises sweat threshold,
Gabapentin MOA?, use?
VMS in menopause, MOA unknown
