Drugs that stimulate the parasympathetic receptors:
Cholinergics
Parasympathomimetics
Cholinergic agonists
Drugs that block the parasympathetic receptors:
Anticholinergics
Parasympatholytics
Cholinergic antagonists
Useful in treating lung disorders – helps smooth muscle to relax
Drugs that stimulate sympathetic receptors:
Adrenergic
Sympathomimetics
Primary type of bronchodilators commonly used
Drugs that block the sympathetic receptors:
Antiadrenergics
Sympatholytics
Beta blocker - primarily used to control cardiac arrhythmias and can cause bronchoconstriction
Trade names are in Capital Letters (proper nouns)
Benzos generally end in “am”
ACE inhibitors generally end in “pril”
Betablockers usually end in “lol”
Corticosteroids usually end in “sone”
In Chapter 10 – Know these tables: 1, 2, 3, 5, 6, 7, 10,
Table 12: anticoagulants, antihistamines, beta-agonists, beta-blockers, calcium channel blockers, cholinergics,
corticosteroids, diuretics, insulin, narcotics, neuromuscular blocking agents, sympathomimetics

Beta 1 usually heart (1), Beta 2 usually is lungs (2)
Epinephrine is both alpha and beta.
•
Epinephrine acts directly on α- and β-adrenergic receptors. Its effect on β-receptors is much more profound, and
includes the following:
• Increased heart rate
• Increased cardiac contractile force
• Increased electrical activity in the myocardium
• Increased systemic vascular resistance
• Increased blood pressure
• Increased automaticity
Precautions for Epinephrine:




Should be protected from light
Can be deactivated by alkaline solutions such as sodium bicarbonate
The IV line must be adequately flushed between administrations of epinephrine and sodium bicarbonate.
The effects of epinephrine can be intensified in patients who are taking antidepressants.
Antidysrhythmics classes- (works on Ventricular dysrhythmias for the heart)
