Drugs act through receptors by binding to the receptors to initiate a response or prevent a response.
Receptor Theory
drugs that produces a response
Agonist
drugs that blocks a response
Antagonist
Has a catechol ring and amines
Catecholamines
has no catechol ring
Noncatecholamines
It influences all receptors
Non-selective
influences one type of receptor
Selective
Hypotension, nasal congestion, dilation of pupils
Alpha 1
Hypertension
Alpha 2
Heart failure, cardiac arrest, shock
Beta 1
Asthma, premature labors of contraction
Beta 2
Prazosin, Terazosin is used for
Hypertension
Pilocarpine is used for
Constricts pupil, decrease IOP for acute glaucoma
this will increases heart rate, force of contraction in heart failure, shock
Dobutamine
