PHARMACODYNAMICS 2 Flashcards
Transport proteins / carrier molecules are located in?
Cell membrane
Pump that facilitates the exit of sodium and entry of potassium in the cell
Sodium - Potassium ATPase pump
(T/F) Digoxin is an inotropic drug
True
Also known as proton pump
H+ - K+ ATPase pump
Drugs that are used to treat peptic ulcer disease (PUD)
Proton Pump Inhibitors
Loop diuretics such as Furosemide are used to treat?
Hypertension (Decreases fluid volume, which decreases blood flow)
Transport protein that facilitates the entry of sodium into the body
Na+ - K+ - 2Cl cotransport
Also known as protein catalyst or increase chemical reactions
Enzymes
Enzyme that converts xanthine into uric acid
Xanthine oxidase
Drug that is used to inhibit Xanthin oxidase to prevent gouty arthritis
Allopurinol
Enzyme that is important in the production of prostaglandins from arachidonic acid
Cyclooxygenase (COX)
Substance that initiate inflammation in the body
Prostaglandins
What are the examples of Non-Steroidal Anti-Inflammatory Drugs
Mefenamic Acid
Ibuprofen
(T/F) NSAID’s inhibit the enzyme Cyclooxygenase (COX) preventing the transformation of arachidonic acid into prostaglandins
True
Enzyme that plays a vital role in RAAS (blood pressure regulation)
Angiotensin-converting enzyme (ACE)
It regulates blood pressure in the body
renin-angiotensin-aldosterone system (RAAS)
Examples of ACE inhibiting drugs (Anti-Hypertensive)
Drugs that end with “pril”
(T/F) Angiotensin II is a vasoconstrictor that is produced by the ACE enzyme from Angiotensin I
True
Enzyme that metabolizes catecholamines (Norepinephrine, Epinephrine, Dopamine)
Mono-amine oxidase (MAO)
What are the examples of Mono-amine oxidase inhibitors
Antidepressants such as:
Phenelzine
Isocarbozaxid
Tranylcypromine
(T/F) MAO Inhibitors inhibit the metabolism of catecholamines increasing their numbers in the brain (Antidepressants)
True
Enzyme that deactivates acetylcholine into Choline + Acetic Acid
Acetylcholinesterase
Examples of drugs that are AcTHE inhibitors
Edrophonium (Diagnostic for Tensilon test)
Organophosphates (Insecticides, may cause DUMBELS)
Enzyme that metabolizes catecholomines (phase II)
Catechol-O-methyl-transferase
Catechol-o-methyl-transferase inhibitors
Entacapone + Levodopa = treatment for parkinsons
Tolcapone + Levodopa = treatment for parkinsons
Macromolecule components of cell with specific stereochemical configuration
Receptors
Refers to any chemical that can bind to a receptor
Ligand
(T/F) Ligands bind using chemical interactions
True
