Lithium is used for manic episodes of bipolar disorder. Which pharmacologic class does it represent?

• A. Antineoplastic
• B. Antimanic
• C. Antituberculosis
• D. Antipyretic

Answer: (B)

Lithium’s main role is as a mood stabilizer that counteracts mania and helps prevent future manic and depressive episodes in bipolar disorder. That makes it an antimanic agent, a category used for drugs that quell mania and stabilize mood over time. The other options don’t fit because they refer to entirely different therapeutic areas: an antineoplastic treats cancer, an antituberculosis drug targets TB, and an antipyretic lowers fever. In clinical use, lithium requires careful long-term monitoring due to a narrow therapeutic window and potential effects on kidney and thyroid function, but its core function relevant to bipolar mania is to stabilize mood and reduce manic symptoms.
