1. Suffixes, Prefixes, Antidotes, & Common Therapeutic Levels
Q1: What is the significance of the suffix "-cillin" in pharmacology?
A1: The suffix "-cillin" indicates that the drug is a penicillin antibiotic. It helps
healthcare providers identify the drug class quickly. Penicillins are used to treat
various bacterial infections by inhibiting cell wall synthesis.
Q2: What does the prefix "beta-" indicate in beta-blockers?
A2: The prefix "beta-" refers to the drug's action on beta-adrenergic receptors in
the heart and lungs. Beta-blockers are used to manage hypertension, angina, and
certain arrhythmias by decreasing heart rate and contractility.
Q3: Name an antidote for acetaminophen overdose and its mechanism of action.
A3: N-acetylcysteine (NAC) is the antidote for acetaminophen overdose. It works
by replenishing glutathione levels in the liver, which helps detoxify harmful
metabolites of acetaminophen, thereby preventing liver damage.
Q4: What are common therapeutic levels for lithium, and why is monitoring
important?
A4: The therapeutic range for lithium is typically 0.6 to 1.2 mEq/L. Monitoring is
crucial to prevent toxicity, which can cause severe neurological and physical
symptoms, including tremors, confusion, and seizures.
,Q5: Define the suffix "-statin" and its relevance in medication.
A5: The suffix "-statin" indicates that the drug is a cholesterol-lowering
medication (HMG-CoA reductase inhibitors). These drugs reduce LDL cholesterol
and are used to prevent cardiovascular disease.
Q6: What is the purpose of the prefix "anti-" in pharmacology?
A6: The prefix "anti-" signifies that the drug has an opposing effect, often relating
to infections or diseases. For example, "antibiotic" means it works against
bacterial infections.
Q7: What is the antidote for warfarin overdose?
A7: Vitamin K is the antidote for warfarin overdose. It helps restore normal
clotting factor synthesis, thus reversing the anticoagulant effects of warfarin and
reducing the risk of bleeding.
Q8: Identify the common therapeutic level for digoxin and the implications of
monitoring.
A8: The therapeutic range for digoxin is typically 0.5 to 2.0 ng/mL. Monitoring is
essential to prevent toxicity, which can lead to arrhythmias and gastrointestinal
disturbances.
Q9: Describe the relevance of the suffix "-pril" in medication.
A9: The suffix "-pril" indicates that the drug is an ACE inhibitor, which is used
primarily to treat hypertension and heart failure by inhibiting the conversion of
angiotensin I to angiotensin II, leading to vasodilation.
Q10: What does the prefix "anti-" in "antidepressants" imply?
, A10: The prefix "anti-" in "antidepressants" indicates that these medications are
used to counteract depressive symptoms, helping to improve mood and
emotional well-being.
Q11: What is the antidote for opioid overdose?
A11: Naloxone (Narcan) is the antidote for opioid overdose. It works by
competitively binding to opioid receptors, reversing the effects of opioids,
including respiratory depression.
Q12: Explain the significance of the suffix "-olol" in pharmacology.
A12: The suffix "-olol" indicates that the drug is a beta-blocker, which is used to
manage conditions such as hypertension, heart failure, and anxiety by blocking
the effects of adrenaline on beta receptors.
Q13: What is the common therapeutic level for theophylline, and why is
monitoring necessary?
A13: The therapeutic range for theophylline is typically 10 to 20 mcg/mL.
Monitoring is crucial to prevent toxicity, which can cause symptoms such as
nausea, arrhythmias, and seizures.
Q14: Identify an antidote for benzodiazepine overdose and its mechanism of
action.
A14: Flumazenil is the antidote for benzodiazepine overdose. It works by
competitively inhibiting the effects of benzodiazepines at the GABA receptor,
reversing sedation and respiratory depression.
Q15: Define the prefix "alpha-" in relation to medications.
