Which medications interact with St. John's Wort? -
ANSWERS-SSRI antidepressants, warfarin, and birth control.
Combining St. John's Wort and SSRI antidepressants, could
lead to an increased serotonin level causing serotonin
syndrome. Combining estrogen containing oral
contraceptives with St. John's Wort can lead to a decreased
efficacy of the contraceptive and eventually unplanned
pregnancies. It is also known to decrease the efficacy of HIV
medications, cholesterol medications, as well as transplant
medications. It should be noted however that traditional
SSRI antidepressants such as fluoxetine carry similar
contraindications. Use nonjudgmental approach so they tell
u what herbs they take. Tricyclics and SJW can increase the
risk for serotonin syndrome.
,Doxazosin - ANSWERS--an alpha-1 adrenergic receptor
blocker that inhibits the binding of norepinephrine released
from sympathetic nerve terminals to the alpha 1 receptors
in the membrane of vascular smooth muscle cells
-the primary effect of this inhibition is relaxed vascular
smooth muscle tone or vasodilation, which decreases
peripheral vascular resistance leading to decrease blood
pressure.
-is used to treat high blood pressure and urinary retention
associated with benign prostatic hyperplasia (BPH).
Doxazosin also shows potential for treatment of benign
prostatic hyperplasia and erectile dysfunction. Doxazosin
has shown some efficacy in in treating chronic epididymitis.
Adverse effects include orthostatic hypotension and reflex
tachycardia.
What is the action of effective beta-blockers? - ANSWERS-
Beta-blockers are a class of drugs that are particularly used
for the management of cardiac arrhythmias, protecting the
heart from a second attack after first heart attack, which is
called secondary prevention.
They have been used in hypertension but no longer our
treatment of first choice.
Beta-blockers block the action of endogenous
catecholamines, epinephrine, and norepinephrine on
, adrenergic beta receptors of the sympathetic nervous
system, which mediates the flight or fight response. Some
block all activation of beta adrenergic receptors and others
are selective.
3 types of beta receptors - ANSWERS-*Beta-1 adrenergic
receptors are located mainly in the heart and kidneys.
*Beta-2 are located in the lungs, GI tract, liver, uterus,
vascular smooth muscle and skeletal muscle.
*Beta-3 adrenergic receptors are located in fat cells.
Beta receptors and stress responses - ANSWERS-Beta
receptors are found on cells of the heart muscles, smooth
muscles, airways, arteries, kidneys, and other tissues that
are part of the sympathetic nervous system and lead to
stress responses especially when they are simulated by
epinephrine. Beta 1 receptors effect chronotropy, inotropy,
dromotropy, renin release and lypolysis.
Beta-blockers interfere with binding of the receptor to
epinephrine and other stress hormones and weaken the
effects of stress hormones.
non selective beta blockers - ANSWERS-show combined to
both beta-1 and beta-2 receptors, those include propranolol
