Pharm General Flashcards
alpha 1
Gq
-Causes smooth muscle constriticion. (arterioles, dilator, bladder)
alpha 2
Gi
- Autoreceptor, inhibits outflow
- Minimizes lipolysis and insulin secretion
B1
Gs
-Heart, Renin release from Kidneys, Lipolysis
B2
- Gs
- Smooth muscle relaxation, insulin release, lipolysis
- Decrease uterine and bronchial smooth muscle tone
- Increase Aqueous humor prouction
D1
- Renal blood flow
- Parkinsons
D2
- Gi
- Schizophrenics have too much
H1-
Gq
-Increases nasal and larimal secretions and pruritis
H2
Gs
-Gastric acid secretion
V1
Gq
Vasculature
V2
Gs
ADH receptor in kidney lead to increased water resportpition
Bethanacol
- Direct Ach Agonist
- Used in post operative ileus and bladder paralysis
Pilocarpine
- AchR gonist, strong
- Used for acute angle closure glaucoma
- Constricts cilliary and sphinter pupillae allowing for flow of aqueous humor
Carbachol
-AchR agonist, weaker version of pilocapine
Methacholine
-Asthma challenge AchR agonist
Neostigmine
AchE inhibitor dose not cross BBB
-Used to treat MG, Post operative NM blockade, postoperative ileus
Pyridostigmin
Same as neo. MG ans postoperative NMJ blockade are two main indication
Edrophonium
short acting
Donepazil
-Increase Ach in alzheimers disease
Physostigmine
-Crosses BBB, used to treat atropine/jimsom weed overdose
Organophaosphate
- irreversible AchE inhibitor cause overactivation of AchR
- Treat with atropine and praladoxime
Atropine, tropicamaide
- Block AchR
- Used in acetylcholine toxicity
- Also used to dilate eyes for opthalmologic exam
Benztropine
-Used to treat tremor in parkinsons
Scopolamine
CNS
Ipra/triproum
-Block AchR in bronchial airway and improve asthma
