BIOM 3090 Final Drugs Exam Questions
With Correct Answers
Clonidine - CORRECT ANSWER✔✔-alpha 2 agonist. Will decrease cAMP
| | | | | | | | |
and decrease neurotransmitter release and increase PSNS activity
| | | | | | | |
therefore decrease BP. Can be used for heroin detox. Toxicity: sedation
| | | | | | | | | | |
and impaired concentration
| |
Prazosin - CORRECT ANSWER✔✔-alpha 1 blocker- will cause salt and
| | | | | | | | | |
water retention but BP will decrease (because a1 causes
| | | | | | | | |
vasoconstriction) the salt and water retention is reflex | | | | | | |
Toxicity: dizziness and palpitations
| | |
Propranol - CORRECT ANSWER✔✔-non selective B blocker- block b1
| | | | | | | | |
decrease rate and force of contraction of heart and decrease cardiac
| | | | | | | | | | |
output. Good antiarrythmic block b1 in kidneys, decrease renin release
| | | | | | | | |
Do not use in patients with asthma, previous bradycardia
| | | | | | | |
Metoprolol - CORRECT ANSWER✔✔-Selective b1 blocker, decrease rate
| | | | | | | |
and force of contraction of heart, decrease cardiac output. Good anti-
| | | | | | | | | |
arrhythmic. Decrease renin release from kidneys.
| | | | | |
Contraindication: bradycardia |
, Sodium nitroprusside - CORRECT ANSWER✔✔-For hypertensive
| | | | | |
emergencies, Nitric oxide (NO) is a part of the drug molecule and will
| | | | | | | | | | | | |
mediate vasodilation viaGC enzyme converting GTP to cGMP this causes
| | | | | | | | |
relaxation of smooth muscle.
| | | | |
Toxicities: cyanide poisoning, hypotension
| | |
Verapamil - CORRECT ANSWER✔✔-long term treatment use. Inhibits
| | | | | | | |
calcium flux into a cell decreasing the arteriole smooth muscle
| | | | | | | | | |
contraction and causing vasodilation. Also blocks calcium entering
| | | | | | | |
cardiac muscle cells and decreases contraction
| | | | |
Toxicities: bradycardia, heart failure, cardiac arrest
| | | | |
Enalapril - CORRECT ANSWER✔✔-ACE inhibitor,stops the conversion of
| | | | | | | |
AI to AII and stops the inhibition of bradykinin. Will cause vasodilation,
| | | | | | | | | | | |
decrease BP. | |
Coughing hypotension and dizziness are side effects
| | | | | |
Losartan - CORRECT ANSWER✔✔-ARB receptor blocker. Blocks the
| | | | | | | |
receptor AII binds to. Will work to decrease blood pressure. Side effects
| | | | | | | | | | | |
include hypotension, dizziness (no cough)
| | | |
Hydrochlorothiazide - CORRECT ANSWER✔✔-thiazide diuretic, inhibits | | | | | |
NaCl transport in the distal tubule therefore increasing fluid excretion.
| | | | | | | | | |
