Q

partial agonists

A

Depends on the activity of the sympathetic nervous system

EX: ligand for receptor is high the drug acts as antagonist, if it is low drugs can bind and activate it

18
Q

BETA blocker effects on the eye

A

Reduce the intraocular pressure and decrease aqueous humor

19
Q

Why is it a bad idea to abruptly stop taking a BETA blocker

A

Your sympathetic nervous system is upregulated while taking which could cause a angina and increase risk of sudden death

20
Q

CNS effects with BETA blockers

A
  • Fatigue
  • Depression
  • sleep disturbances

No clear correlation

21
Q

Propranolol clinical use

A

Treats hypertension, Angina pectoris , cardiac arrhythmias, myocardial infraction, and pheochromocytoma, migrane, tremor

22
Q

propranolol adverse effects

A

cardiovascular, bradycardia, hypotension, heart failure, fatigue ,withdrawal symptoms, bronchospasm,

23
Q

timolol Clinical use

A

Treatment of glaucomal, which decreases aqueous humor concentration

(Timmy got sum glasses)

24
Q

metoprolol clinical use

A

Hypertension,Cardiovascular, angima, congestive heart
failure C.A.C.H

(slows heart)

25
Metroprolol adverse effects
Overlap with propranolol . Less risk of bronchoconstriction. Mediated by B2 receptors -blurry, bradychardia, hypotension : METRO TOOK A BEAN
26
Esmolol clinical use
(B1) Administered when a beta blockade of short duration is desired. Mainly used to treat tachycardia
27
Esmolol Adverse Effect
Ultra short acting 1/2 life of 8 minutes
28
labetalol function
Antagonist for Beta 1 and Beta 2 receptors as well as Alpha 1 receptors Treats hypertensive emergencies
29
Labetalol clinical use
treats hypertension and treats hypertensive emergency
30
carvedilol function
antagonist for Alpha 1 and both beta receptors, but has anti-oxidant and anti inflammatory type properties - Slows heart making it easier for blood pumping
31
carvedilol clinical use
treat acute myocardial infraction, HTN, and heart failure MHH
32
Nebivolol function
B1 antagonist and stimulates nitric oxidate release.
33
Nebivolol clinical use
treat hypertension
34
drugs used following a myocardial infraction
Timolol, Propranolol, metoprolol
35
advantages of beta blockers in cardiac arrythmias
slows ventricular response rates to atrial flutter and fibrillation
36
advantages of beta blockers in heart failure
effective in reducing mortality in patients with chronic heart failure
37
drugs to reduce heart failure
metoprolol, bisoprolol, and carvedilol M.B.C
38
What type of beta blockers are suitable for local use in the eye
Beta blockers that lack local anesthetic properties
39
Beta blocker affects on hyperthyroidism
Beta blockers assist and make symptoms better in hyperthyroidism
40
Beta blockers for migraines
propranolol, metoprolol, timolol: PMT (same drugs used for post acute MI) probably effective: atenolol, nadolol
41
Beta blocker for anxiety and tremors
propranolol
42
When choosing a beta blocker what must be considered
comorbidities such as diabetes or other diseases
