What is the primary mechanism of action for beta-blockers? Answer:
Blocking beta-adrenergic receptors Beta-blockers reduce heart rate and blood
pressure by decreasing adrenaline and noradrenaline effects.
. Which of the following is a common side effect of opioid analgesics?
Answer: Constipation Opioids slow gastrointestinal motility, causing
constipation.
. What is the therapeutic use of warfarin? Answer: Anticoagulation
Warfarin prevents blood clots in conditions like atrial fibrillation and deep vein
thrombosis.
. Which class of drugs is commonly used to treat hypertension? Answer:
Diuretics Diuretics reduce fluid retention and lower blood pressure.
. What is the antidote for acetaminophen overdose? Answer: N-
acetylcysteine This antidote replenishes glutathione stores and prevents liver
damage.
. Which drug is classified as a proton pump inhibitor (PPI)? Answer:
Omeprazole Omeprazole reduces stomach acid by blocking the enzyme
responsible for acid secretion.
. What is the primary use of digoxin? Answer: Management of heart failure
Digoxin improves heart contractions, especially in heart failure and atrial
fibrillation.
. Which of the following is a common side effect of ACE inhibitors?
Answer: Dry cough ACE inhibitors increase bradykinin levels, leading to a
persistent dry cough.
. What is the mechanism of action of insulin? Answer: Stimulating glucose
uptake by cells Insulin helps glucose enter muscle and fat cells while promoting
glycogen synthesis in the liver.
,. Which drug is commonly used to reverse opioid overdose? Answer:
Naloxone Naloxone rapidly reverses opioid overdose by blocking opioid
receptors.
. What is the therapeutic use of furosemide? Answer: Diuretic treatment
Furosemide treats fluid retention and hypertension by promoting sodium and
water excretion.
. Which drug is classified as a benzodiazepine? Answer: Diazepam
Diazepam is a benzodiazepine with sedative and muscle relaxant properties.
. What is the primary use of statins? Answer: Reducing cholesterol levels
Statins inhibit HMG-CoA reductase, lowering cholesterol.
. Which of the following is a common side effect of corticosteroids?
Answer: Weight gain Corticosteroids cause weight gain due to increased
appetite and fluid retention.
. What is the mechanism of action of aspirin as an antiplatelet agent?
Answer: Inhibiting cyclooxygenase (COX) enzymes Aspirin reduces
thromboxane A2 production, preventing platelet aggregation.
. What is the primary mechanism of action for calcium channel blockers?
Answer: Blocking calcium entry into cells Calcium channel blockers relax
blood vessels and reduce heart workload by preventing calcium from entering
muscle cells.
. Which drug is commonly used to treat hypothyroidism? Answer:
Levothyroxine Levothyroxine is a synthetic thyroid hormone that replaces
deficient thyroid hormones.
. What is the therapeutic use of albuterol? Answer: Bronchodilation
Albuterol is a beta-agonist that relaxes airway muscles, relieving
bronchospasms in asthma and COPD.
. Which of the following is a common side effect of loop diuretics? Answer:
Hypokalemia Loop diuretics increase potassium excretion, leading to low
potassium levels.
. What is the mechanism of action of heparin? Answer: Inhibiting clotting
factors Heparin enhances antithrombin activity, preventing clot formation.
. Which drug is classified as an H2 receptor antagonist? Answer:
Ranitidine Ranitidine reduces stomach acid by blocking histamine H2 receptors
in the stomach lining.
, . What is the primary use of metformin? Answer: Management of type 2
diabetes Metformin lowers blood glucose by reducing liver glucose production
and improving insulin sensitivity.
. Which of the following is a common side effect of anticholinergic drugs?
Answer: Dry mouth Anticholinergic drugs block acetylcholine, reducing saliva
production and causing dry mouth.
. What is the antidote for benzodiazepine overdose? Answer: Flumazenil
Flumazenil is a benzodiazepine antagonist that reverses sedation and
respiratory depression.
. Which drug is commonly used to treat gout? Answer: Allopurinol
Allopurinol reduces uric acid production, preventing gout attacks.
. What is the therapeutic use of nitroglycerin? Answer: Treatment of angina
Nitroglycerin dilates blood vessels, improving blood flow and relieving chest
pain.
. Which of the following is a common side effect of SSRIs (Selective
Serotonin Reuptake Inhibitors)? Answer: Nausea SSRIs increase serotonin
levels, which can cause nausea as a side effect.
. What is the mechanism of action of sulfonylureas? Answer: Stimulating
insulin secretion Sulfonylureas stimulate the pancreas to release more insulin,
lowering blood glucose levels.
. Which drug is classified as an antiepileptic? Answer: Phenytoin Phenytoin
is used to prevent and control seizures by stabilizing neuronal activity.
. What is the primary use of clopidogrel? Answer: Prevention of blood clots
Clopidogrel inhibits platelet aggregation, reducing the risk of stroke and heart
attack
. What is the primary mechanism of action for angiotensin-converting
enzyme (ACE) inhibitors? Answer: Inhibiting the conversion of angiotensin I
to angiotensin II ACE inhibitors lower blood pressure by preventing the
formation of angiotensin II, a vasoconstrictor.
. Which drug is commonly used to treat Parkinson's disease? Answer:
Levodopa Levodopa is converted to dopamine in the brain, helping to manage
Parkinson's symptoms.
. What is the therapeutic use of atropine? Answer: Treatment of bradycardia
Atropine increases heart rate by blocking the parasympathetic nervous system.
