Question

Match List I with List II
List I:
A. Dissociative anaesthetic
B. Antiseptic
C. Barbiturate
D. Benzodiazepine derivative
List II:
I. Chlorhexidine
II. Phencyclidine
III. Thiamylal
IV. Midazolam
V. Naloxone
Choose the correct answer from the options given below:

• A. A-II, B-I, C-III, D-IV
• B. A-I, B-II, C-III, D-IV
• C. A-II, B-I, C-IV, D-V
• D. A-V, B-IV, C-I, D-II

Hint:

Identifying midazolam as a benzodiazepine (D-IV) and chlorhexidine as an antiseptic (B-I) quickly narrows down the options in competitive exams.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Veterinary pharmacology requires categorizing chemical agents based on their therapeutic applications, mechanisms of action, and chemical families.

Step 2: Detailed Explanation:
Let us analyze and match the items in List I with the chemical agents in List II:
- A. Dissociative anaesthetic: These agents interrupt transmission between the diencephalon and the association areas of the brain.
Phencyclidine (II) is a classic dissociative anesthetic (along with ketamine and tiletamine).
- B. Antiseptic: These are chemical agents applied to living tissues to inhibit or destroy microorganisms.
Chlorhexidine (I) is a widely used biguanide antiseptic.
- C. Barbiturate: These are central nervous system depressants derived from barbituric acid.
Thiamylal (III) is an ultra-short-acting thiobarbiturate used for anesthetic induction.
- D. Benzodiazepine derivative: These are minor tranquilizers that enhance GABA-mediated inhibition.
Midazolam (IV) is a highly water-soluble benzodiazepine derivative.
- Note: Naloxone (V) is an opioid antagonist, which remains unmatched.
Combining these: A \(\rightarrow\) II, B \(\rightarrow\) I, C \(\rightarrow\) III, D \(\rightarrow\) IV.

Step 3: Final Answer:
The correct matching sequence is A-II, B-I, C-III, D-IV.
