Drugs on Exam 1 Flashcards
Acetylcholine
Muscarinic and Nicotinic Receptor Agonists
Used to treat conditions such as Myasthenia gravis and Alzhiemers disease
Bethanechol
Direct Muscarinic Receptor Agonist
Treats Urinary retention / paralytic ileus
Is a direct-acting cholinergic agonist
Is a choline ester that exerts minimal effects in the CNS Has greater affinity for muscarinic receptors than
nicotinic receptor
Causes SLUDGE in overdose
Pilocarpine
Direct Muscarinic Receptor Agonist
Treatment for Glaucoma and Xerostomia
Nicotine
Nicotinic Receptor Agonist
Overdose can cause can cause convulsions, respiratory paralysis, hypertension, arrhythmias (nicotinic ganglia and neuromuscular junction receptor effects)
Atropine
Direct Muscarinic Receptor Antagonist
Treatment of acute, severe bradycardia in coronary care unit
Treatment to reduce salivary and bronchial secretions
Antidote for SLUDGE
Physostigmine
Slowly reversible Acetylcholinesterase Inhibitor
Treatment of antimuscarinic (e.g., atropine, tricyclic antidepressants) drug intoxication
ENTERS CNS
Neostigmine
Slowly reversible Acetylcholinesterase Inhibitor
(Indirect Cholinergic Agonist)
Used as a treatment for Myasthenia gravis
Rapid reversal of neuromuscular blockade (paralysis) produced by nondepolarizing blockers to shorten post-op recovery time following surgical procedures
Treats Urinary retention / paralytic ileus
Edrophonium
Acetylcholinesterase Inhibitor
(Indirect Cholinergic Agonist)
Used as a treatment for Myasthenia gravis
Rapid reversal of neuromuscular blockade (paralysis) produced by nondepolarizing blockers to shorten post-op recovery time following surgical procedures
Organophosphates
Irreversible Acetylcholinesterase Inhibitor
(Indirect Cholinergic Agonist)
SLUDGE effects
