Show Hint
Phenothiazines = Antipsychotics = CNS Depression.
Updated On: May 15, 2026
- Depression of the CNS
- Reduction of hepatic enzyme activity
- Entirely binds with iodine
- Stimulation of CNS
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Phenothiazines are a class of antipsychotic (neuroleptic) drugs.
Step 2: Meaning
Antipsychotics work by blocking dopamine receptors ($D_{2}$) in various brain pathways.
Step 3: Analysis
The primary pharmacological effect of this class is a sedative and calming effect, leading to central nervous system (CNS) depression.
Step 4: Conclusion
Therefore, phenothiazines act as CNS depressants. Final Answer: (A)
