Beta blockers are known to depress myocardial contractility and excitability, thus caution must be exercised in giving this drug to patients with what condition?
COMPENSATED HEART FAILURE
Drugs that mimic the actions of epinephrine or norepinephrine have traditionally been termed
Sympathomimetic drugs.
Of the adrenoceptors, this one is responsible for actions over juxtaglomerular cells.
BETA-1 adrenoreceptors
This is a reaction of the SNS that causes certain muscles to contract and hair follicles to protrude outward from the skin
PILOERECTION or GOOSEBUMPS
Coming from the directing-acting alpha agonists class, it can be used for nasal decongestion, mydriasis and for hypotension
PHENYLEPHRINE
This is a direct-acting αlpha agonist used as a topical decongestant because of its ability to promote constriction of the vessels in the nasal mucosa and conjunctiva.
Oxymetazoline
