Class of drugs derived from barbituric acid that act as CNS depressants and are used for their sedative and anti- seizure effect are known as _
Correct answer
Antidepressants treat mood disorders. Anxiolytics reduce anxiety but aren't barbituric-derived. Barbiturates fit the description. Benzodiazepines aren't barbituric-based.
Rationale
The correct answer is C: Barbiturates. Barbiturates are drugs derived from barbituric acid, acting as CNS depressants for sedative and anti-seizure effects. Antidepressants (A) are used for mood disorders, not CNS depression. Anxiolytics (B) are for anxiety and not all are barbituric-derived. Benzodiazepines (D) are a different class of CNS depressants, not derived from barbituric acid. Therefore, choice C is the most appropriate based on the specific description provided in the question.
