Test Questions with
Correct Answers
Competitive antagonist drugs - Answer--Have a higher binding affinity than the
neurotransmitter to a receptor
-Blocks neurotransmitter from binding
Non-competitive antagonist - Answer-Are drugs that bind to receptor sites to block the
effects of the agonist
Angiotensin-converting enzyme (ACE) inhibitors "perils" - Answer-Block conversion of
angiotensin I to angiotensin II (lower BP by vasodilation; decreasing preload and
afterload)
e.i., ramipril, captopril, lisinopril, enalapril
Angiotensin II Receptor Blockers (ARBs)- "sartans" - Answer-Often prescribed as
alternative when pt develop persistent cough from ACEi
-it decrease afterload and preload by promoting diuresis & vasodilation
-ex candesartan, losartan, valsartan
Therapeutic effect of ACEI & ARB - Answer--vasodilation
-reduced aldosterone release
-reduced ADH release
-reduced growth effects to A II on the heart
Beta 1 receptors - Answer-located primarily in the heart and kidneys
- result in increase HR, increase contractility of heart
-release of Renin (RASS) causes increase in BP
Beta 2 receptors - Answer-Located in: smooth muscles-smooth muscle relaxation
Lungs-bronchodilation
Arteries that supply blood to SM and coronary arteries - vasodilate
GI tract- decrease peristalsis & digestion
Liver-Gluconeogenesis
Pancreas- increase release of insulin
, Beta 3 receptors - Answer-primarily in adipose cells and smooth muscle cells in walls of
digestive tract
Pharmacotherapy - Answer-use of drugs to treat, prevent and diagnose disease
Pharmacokinetics - Answer-The process by which drugs are absorbed, distributed
within the body, metabolized(bio transformation), and excreted.
Pharmacodynamics - Answer-The way the drug affects the body
Adverse effects - Answer-unintended and usually undesired of a drug
Contraindications/Precautions - Answer-A specific situation in w/c a drug should not be
used because it could cause harm
Drug interactions - Answer-the effects that may occur when the drug is given along with
another drug, food, or substance
Adverse Reaction/ Side effects - Answer-Side effects are CAPITALIZED & most
frequent side effects are underlined
Agonist - Answer-Activates
Antagonist - Answer-Prevents activation
Affinity - Answer-ability of a drug to bind to a receptor
efficacy - Answer-Measure how well a drug produces a response
Potency - Answer-The amt of drug req for a given response
receptor sites - Answer-Many drugs are thought to act at specific areas on cell
membranes
Agonist (Receptor site ) - Answer-Drugs that interact directly w/ receptor sites to cause
the same activity that natural chemicals would cause at that site
1st Generation Beta blockers - Answer-non-selective/non specific (binds to both B1 and
B2 receptors)
Timolol, Propranolol, Sotalol
2nd Generation Beta Blockers - Answer-B1 selective *can also bind to B2 w/ higher
concentration
-metoprolol
-Bisoprolol
