A drug ending in the suffix (azole) is considered a ______.
- A. H
- B. ACE inhibitor
- C. Antifungal
- D. Beta agonist
Correct Answer: C
Rationale: The correct answer is C: Antifungal. Drugs ending in the suffix (azole) are commonly used to treat fungal infections. The suffix indicates that the drug belongs to the azole class, which specifically targets fungal pathogens by inhibiting their growth. Therefore, a drug ending in (azole) is classified as an antifungal medication.
Summary of other choices:
A: H - Incorrect. There is no pharmacological relevance to the suffix (azole) in relation to the letter H.
B: ACE inhibitor - Incorrect. Drugs ending in (pril) are commonly ACE inhibitors, not those ending in (azole).
D: Beta agonist - Incorrect. Drugs ending in (ol) or (olol) are typically beta agonists, not those ending in (azole).

Which of the following conditions is not treated with Methotrexate?
- A. Sarcomas
- B. Leukemias
- C. Ectopic pregnancy
- D. Rheumatic fever
Correct Answer: D
Rationale: The correct answer is D: Rheumatic fever. Methotrexate is not typically used to treat rheumatic fever as it is an autoimmune inflammatory condition, not typically responsive to Methotrexate. Methotrexate is commonly used to treat sarcomas, leukemias, and ectopic pregnancies due to its ability to inhibit cell proliferation. Sarcomas and leukemias are types of cancers, while ectopic pregnancy is a condition where a fertilized egg implants outside the uterus.
Which of the following drugs is associated with the reaction of Cinchonism?
- A. Valproic acid
- B. Quinidine
- C. Isoniazid
- D. Ethosuximide
Correct Answer: B
Rationale: The correct answer is B: Quinidine. Cinchonism is a condition caused by the toxicity of Cinchona alkaloids, which are found in drugs like quinine and quinidine. Quinidine is specifically known to cause symptoms of cinchonism such as tinnitus, headache, blurred vision, and nausea. Valproic acid (choice A) is an anticonvulsant, not associated with cinchonism. Isoniazid (choice C) is an antibiotic used to treat tuberculosis and does not cause cinchonism. Ethosuximide (choice D) is an anticonvulsant used to treat absence seizures and is not linked to cinchonism.
Which of the following conditions is not treated with Ephedrine?
- A. COPD
- B. Hypotension
- C. Congestion
- D. Incontinence
Correct Answer: A
Rationale: The correct answer is A: COPD. Ephedrine is a sympathomimetic drug that acts on alpha and beta adrenergic receptors, leading to vasoconstriction and increased heart rate. It is used to treat hypotension and congestion by increasing blood pressure and dilating airways, respectively. Incontinence is not typically treated with Ephedrine. However, COPD involves bronchoconstriction, which can worsen with Ephedrine due to its vasoconstrictive effects. Therefore, Ephedrine is not used to treat COPD.
Which of the following drugs is associated with Stevens-Johnson syndrome?
- A. Valproic acid
- B. Quinidine
- C. Isoniazid
- D. Ethosuximide
Correct Answer: D
Rationale: Step 1: Ethosuximide is the correct answer as it is a known trigger for Stevens-Johnson syndrome due to its association with hypersensitivity reactions.
Step 2: Valproic acid can cause liver toxicity but is not typically linked to Stevens-Johnson syndrome.
Step 3: Quinidine is associated with drug-induced lupus but not commonly known to cause Stevens-Johnson syndrome.
Step 4: Isoniazid is linked to drug-induced hepatitis but not typically associated with Stevens-Johnson syndrome.
In summary, Ethosuximide is the correct choice due to its well-documented association with Stevens-Johnson syndrome, while the other options are linked to different adverse effects.
A drug ending in the suffix (navir) is considered a ______.
- A. Antidepressant
- B. Protease inhibitor
- C. Beta antagonist
- D. H antagonist
Correct Answer: B
Rationale: The correct answer is B: Protease inhibitor. Drugs ending in the suffix (navir) are commonly used to inhibit protease enzymes in viruses, particularly in the treatment of HIV/AIDS. Protease inhibitors disrupt viral replication by preventing the cleavage of viral proteins, thus inhibiting the production of new infectious viral particles.
Choice A, Antidepressant, is incorrect as drugs used to treat depression usually end in (ine) or (pram).
Choice C, Beta antagonist, is incorrect as drugs affecting beta receptors typically end in (olol) or (lol).
Choice D, H antagonist, is incorrect as drugs targeting histamine receptors usually end in (ine) or (idine).
