Pharmacology Flashcards
Alpha 1
- Vasoconstriction
- Mydriasis
- Intestinal and bladder sphincter contraction
Alpha 2
Decreases sympathetic tone: (-) feedback
Decrease Insulin release
Beta 1
Inc. HR
Inc. Contractility
Inc. lipolysis
Inc. renin release
Beta 2
Bronchodilation
Vasodilation (reflex tachycardia, cont)
Inc. insulin release
Dec. uterine tone (tocolytic)
Inc. aqueous humor production
M1
CNS
Enteric NS
M2
Dec. HR
Dec. Contractilty
M3
Inc. Gland secretion Inc. gut peristalsis Inc. bladder contraction Bronchoconstriction Miosis Accomodation
Increase Insulin
D1
Kidneys - relaxes vascular smooth muscle
D2
CNS - modulates transmitter release
H1
Allergy Sx:
Inc. Nasal and Bronchial mucus production
Inc. Vascular permeability
Inc. contraction bronchioles
Pruritis, Pain
H2
Inc. Gastric Acid Secretion
V1
vasoconstriction
V2
kidney - Inc. H20 permeability and reabsorption in collecting tubules (V2 for 2 kidneys)
G protein coupler receptors
Gq: HAV1 M1&M3
Gi: MAD2
GS: everything else
Hemicholinium
Inhibit Choline-Na transporter
Vesamicol
Inhibit Ach packaging into vesicles
Botulinum
Inhibit exocytosis of Ach
Black Widow Spider Toxin
Stimulate exocytosis of Ach
Metyrosine
Inhibit Tyrosine hydroxylase: Tyr –> L-DOPA
Reserpine
Inhibit NE packaging into vesicles
Drugs that stimulate NE release
Amphetamine
Tyramine
Ephedrine
Drugs that inhibit NE Reuptake
Cocaine
TCA
Drugs that inhibit NE exocytosis
Bretylium
Guanethidine
Metabolism of NE
COMT
MAO
Dopa -> HVA
NE -> VMA
Epi -> Metanephrine
