Question

Administration of caffeine with choral hydrate comes under ______ incompatibility.

• A. Physical
• B. Chemical
• C. Therapeutic
• D. Tolerable

Hint:

Stimulant + Depressant = Opposing actions = Therapeutic Incompatibility.

Answer 1

The Correct Option is C

Step 1: Concept
Pharmaceutical incompatibility occurs when the mixing of two or more substances results in an undesirable product.

Step 2: Meaning
Therapeutic incompatibility refers to an interaction where the pharmacological action of one drug opposes or excessively enhances another.

Step 3: Analysis
Caffeine is a central nervous system (CNS) stimulant, while chloral hydrate is a CNS depressant (sedative-hypnotic). Administering them together results in opposing therapeutic effects.

Step 4: Conclusion
Because the conflict is between their medicinal actions rather than their chemistry or physical state, it is a therapeutic incompatibility.

Final Answer: (C)
