Brands of epinephrine, ephedrine, ethylnorepinephrine?
Primatene
Bronkaid
Adrenalin
Medihaler-Epi
Bronitin
Epinephrine is in the pharmacologic class?
beta2-agonist bronchodilators that work by stimulating both BETA (BRONCHO) and alpha (AWAY FROM BRONCHO...ex: arterial constriction in mucous membranes...useful as nasal decongestant) receptors
Beta2-stimulation properties result in?
BRONCHODILATION....this is achieved by stimulation of beta2 located throughout lungs...causes constricted airways to dilate..

conversely, a NONSPECIFIC beta-blocker (epinephrine) would cause airways to constrict

conversely, the alpha receptor stimulation has effects ELSEWHERE in the body...one is mucous membrane arteriolar constriction...useful as nasal decongestant
Epinephrine is available with or without?
prescription
(treats asthma)
Ephedrine and ethylnorepinephrine are available only with a?
prescription
Beta-agonists ex: epinephrine are commonly used in which phase of an asthmatic attack?
ACUTE!
Beta-agonists stimulate?
SNS
Beta-agonists are also called?
sympathomimetic bronchodilators
Epinephrine is a NONSELECTIVE adrenergic drug...true or false?
true...it stimulates alpha, beta1 (cardiac) and beta2 (respiratory) receptors

the beta1 (cardiac) stimulation is an UNWANTED side effect because it increases heart rate and force of contraction

the stimulation of alpha causes vasoconstriction which is helpful as it reduces amount of edema and swelling of mucous membranes and limits quantity of secretions normally secreted from these membranes
A patient taking epinephrine and a hypoglycemic agent may need?
an adjustment in their dose because of the increased blood glucose levels that can occur
