Catecholamines

4
Q

acting on different adrenergic receptors

A

Nonselective

5
Q

acting on one adrenergic receptor (EX: albuterol)

A

Selective

6
Q

drugs that block the effects of adrenergic neurotransmitters…“sympatholytics”

A

Adrenergic Blockers (Antagonists)

7
Q

drugs that block/inhibit a response at the alpha-adrenergic receptor site

Alpha-Blockers

8
Q

drugs that block/inhibit a response at the beta-adrenergic receptor site

A

Beta-Blockers

9
Q

drugs that stimulate the parasympathetic nervous system

A

Cholinergic Agonists (“Cholinergics” or “Parasympathomimetics”)

10
Q

neurotransmitter located at the ganglions and the parasympathetic terminal nerve endings

A

Acetylcholine (ACh)

11
Q

receptors in the parasympathetic nervous system that stimulate smooth muscle and slow the heart rate

A

Muscarine Receptors

12
Q

receptors in the parasympathetic nervous system that affect the skeletal muscles

13
Q

drugs that act on cholinergic receptors to activate a tissue response

A

Direct-Acting Cholinergic Agonists

14
Q

drugs that inhibit or inactivate the action of the enzyme cholinesterase (ChE)

A

Indirect-Acting Cholinergic Agonists

15
Q

drugs that inhibit cholinesterase (ChE)

A

Anticholinesterases (“Cholinesterase Inhibitor” or “Acetylcholinesterase (AChE) Inhibitors”)

16
Q

enzyme that catalyzes the hydrolysis of choline esters, such as acetylcholinesterase, which catalyzes the breakdown of acetylcholine to acetic acid & choline

A

Cholinesterase (ChE)
