200 QUESTIONS AND ANSWERS
Pharmacology
1. Which of the following neurotransmitters is primarily associated with
Parkinson's disease pathophysiology?
• A) Serotonin
• B) Dopamine
• C) Acetylcholine
• D) GABA
Answer: B) Dopamine. Parkinson's disease is characterized by the
degeneration of dopaminergic neurons in the substantia nigra, leading to
reduced dopamine levels.
,2. Propranolol is classified as:
• A) Selective β1-adrenergic antagonist
• B) Non-selective β-adrenergic antagonist
• C) α1-adrenergic antagonist
• D) Mixed α and β antagonist
Answer: B) Non-selective β-adrenergic antagonist. Propranolol blocks both
β1 and β2 receptors.
3. Which of the following is NOT a common adverse effect of ACE
inhibitors?
• A) Dry cough
• B) Hyperkalemia
• C) Thrombocytopenia
• D) Angioedema
Answer: C) Thrombocytopenia. While ACE inhibitors can cause dry cough,
hyperkalemia, and angioedema, thrombocytopenia is not a common adverse
effect.
4. The mechanism of action of furosemide involves:
• A) Inhibition of Na⁺-K⁺-2Cl⁻ cotransporter in the ascending loop of Henle
• B) Antagonism of aldosterone receptors
• C) Inhibition of carbonic anhydrase
• D) Blockade of sodium channels in the distal tubule
Answer: A) Inhibition of Na⁺-K⁺-2Cl⁻ cotransporter in the ascending loop
of Henle. This is the main mechanism of action of loop diuretics.
5. Which calcium channel blocker is most frequently associated with
gingival hyperplasia?
• A) Amlodipine
• B) Nifedipine
• C) Diltiazem
• D) Verapamil
Answer: B) Nifedipine. Though all calcium channel blockers can cause
gingival hyperplasia, nifedipine has the highest incidence.
,6. The primary mechanism of antidepressant action for selective serotonin
reuptake inhibitors (SSRIs) is:
• A) Inhibition of monoamine oxidase
• B) Blockade of serotonin receptors
• C) Inhibition of serotonin reuptake
• D) Enhancement of norepinephrine release
Answer: C) Inhibition of serotonin reuptake. SSRIs selectively block the
reuptake of serotonin, increasing its concentration in the synaptic cleft.
7. Which of the following opioid analgesics is a partial agonist at μ-opioid
receptors?
• A) Morphine
• B) Fentanyl
• C) Buprenorphine
• D) Methadone
Answer: C) Buprenorphine. Buprenorphine acts as a partial agonist at μ-
opioid receptors and an antagonist at κ-opioid receptors.
8. Proton pump inhibitors work by inhibiting:
• A) H⁺/K⁺-ATPase
• B) Na⁺/K⁺-ATPase
• C) H⁺/Na⁺ exchanger
• D) Carbonic anhydrase
Answer: A) H⁺/K⁺-ATPase. PPIs irreversibly inhibit the hydrogen/potassium
adenosine triphosphatase enzyme system in gastric parietal cells.
9. Which of the following is an NMDA receptor antagonist used for
Alzheimer's disease?
• A) Donepezil
• B) Memantine
• C) Rivastigmine
• D) Galantamine
Answer: B) Memantine. Memantine is an NMDA receptor antagonist, while
the others are acetylcholinesterase inhibitors.
, 10. The primary mechanism of action of HMG-CoA reductase inhibitors
(statins) is:
• A) Inhibition of cholesterol absorption in the intestine
• B) Inhibition of bile acid reabsorption
• C) Inhibition of cholesterol synthesis in the liver
• D) Enhancement of LDL receptor degradation
Answer: C) Inhibition of cholesterol synthesis in the liver. Statins inhibit
HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis.
11. Which of the following antidepressants has the highest risk of causing
serotonin syndrome when combined with MAOIs?
• A) Bupropion
• B) Mirtazapine
• C) Fluoxetine
• D) Trazodone
Answer: C) Fluoxetine. As an SSRI with a long half-life, fluoxetine poses a
significant risk of serotonin syndrome when combined with MAOIs.
12. Naloxone is used to reverse opioid overdose because it is an:
• A) Opioid agonist
• B) Opioid antagonist
• C) Opioid partial agonist
• D) Opioid enzyme inducer
Answer: B) Opioid antagonist. Naloxone competitively binds to opioid
receptors, displacing opioid agonists and reversing their effects.
13. Which of the following is a sodium-glucose cotransporter 2 (SGLT2)
inhibitor?
• A) Sitagliptin
• B) Empagliflozin
• C) Liraglutide
• D) Pioglitazone
Answer: B) Empagliflozin. Empagliflozin is an SGLT2 inhibitor that reduces
blood glucose by promoting urinary glucose excretion.
14. Doxorubicin's cardiotoxicity is primarily due to:
• Pharmacology
• Medicinal Chemistry
• Pharmaceutics
• Pharmacokinetics
• Pharmacotherapy
• Pharmaceutical Care and Clinical Pharmacy
• Pharmacy Law and Ethics
• Pharmacognosy and Natural Products
