Chlorpromazine is an example of which drug class?

Explanation:
Chlorpromazine is classified as a phenothiazine, a group of typical antipsychotic drugs. These medications share a phenothiazine chemical structure and work mainly by blocking dopamine D2 receptors in the brain, especially in pathways involved in psychosis like the mesolimbic system. This receptor antagonism helps reduce positive symptoms of schizophrenia such as hallucinations and delusions. Chlorpromazine was one of the first antipsychotics and also has sedative effects due to its broader CNS activity. The other options belong to different drug classes: benzodiazepines are GABA-A receptor modulators used for anxiety and sedation, theophylline is a methylxanthine bronchodilator and stimulant, and amikacin is an aminoglycoside antibiotic.
