#2
Which of the following is a common side effect of opioids?
Respiratory depression
ExplanationRespiratory depression is a common side effect of opioids, affecting the central respiratory centers in the brain.
#3
Which of the following drugs is commonly used to treat attention deficit hyperactivity disorder (ADHD)?
Methylphenidate

#5
Which of the following drugs is commonly used to treat peptic ulcers by inhibiting gastric acid secretion?
Omeprazole
ExplanationOmeprazole is commonly used to treat peptic ulcers by inhibiting gastric acid secretion and promoting ulcer healing.
#6
Which neurotransmitter is primarily targeted by selective serotonin reuptake inhibitors (SSRIs)?
Serotonin
ExplanationSSRIs primarily target serotonin, inhibiting its reuptake and increasing its availability in the synaptic cleft, contributing to mood regulation.
#7
What is the primary mechanism of action of beta-blockers?
Antagonism of adrenergic receptors
ExplanationBeta-blockers work by antagonizing adrenergic receptors, particularly beta receptors, leading to decreased heart rate and blood pressure.
#8
Which class of drugs is commonly prescribed for the treatment of hypertension and heart failure?
Angiotensin-converting enzyme (ACE) inhibitors
ExplanationACE inhibitors are commonly prescribed for hypertension and heart failure, inhibiting the conversion of angiotensin I to angiotensin II.
#9
What is the primary mechanism of action of statins?
Inhibition of HMG-CoA reductase
ExplanationStatins inhibit HMG-CoA reductase, reducing cholesterol synthesis and lowering blood cholesterol levels.
#10
Which medication is commonly used as an antiplatelet agent to prevent blood clot formation?
Clopidogrel
ExplanationClopidogrel is commonly used as an antiplatelet agent, preventing blood clot formation by inhibiting platelet activation.
#11
Which of the following drugs is a selective serotonin and norepinephrine reuptake inhibitor (SNRI)?
Venlafaxine
ExplanationVenlafaxine is an SNRI that primarily inhibits the reuptake of serotonin and norepinephrine, impacting mood regulation.
#12
What is the primary mechanism of action of proton pump inhibitors (PPIs)?
Inhibition of gastric acid secretion
ExplanationProton pump inhibitors (PPIs) work by inhibiting the proton pump in gastric cells, reducing the secretion of gastric acid.
#13
Which of the following drugs is used as a first-line treatment for uncomplicated malaria?
Artemether-lumefantrine
ExplanationArtemether-lumefantrine is a first-line treatment for uncomplicated malaria, acting against Plasmodium parasites.
#14
Which class of drugs is commonly used to treat type 2 diabetes by decreasing hepatic glucose production and enhancing insulin sensitivity?
Biguanides
ExplanationBiguanides, like metformin, treat type 2 diabetes by decreasing hepatic glucose production and improving insulin sensitivity.
#15
Which medication is commonly used as a first-line treatment for rheumatoid arthritis by inhibiting TNF-alpha?
Etanercept
ExplanationEtanercept is commonly used in rheumatoid arthritis, inhibiting TNF-alpha and reducing inflammation.
#16
Which medication is commonly used for the treatment of opioid addiction by blocking opioid receptors?
Naltrexone
ExplanationNaltrexone is used for opioid addiction by blocking opioid receptors, reducing the rewarding effects of opioids.
#17
Which medication is commonly used as a first-line treatment for acute mania in bipolar disorder?
Lithium
ExplanationLithium is commonly used as a first-line treatment for acute mania in bipolar disorder, stabilizing mood and preventing manic episodes.
