When did antipsychotics become available?

• A. Mid-20th century advancements
• B. Early 19th century innovations
• C. 21st century developments
• D. Late 20th century stagnation

Answer: (A)

The main idea here is when pharmacologic treatment for psychosis first became available, marking the birth of modern antipsychotic drugs. Antipsychotics entered medical use in the mid-20th century. The first widely impactful drug, chlorpromazine, was introduced in the early 1950s and became widely used by the mid-1950s, transforming care for schizophrenia and related conditions by providing a chemical means to reduce psychotic symptoms. This breakthrough shifted psychiatry from largely custodial approaches to active pharmacologic management. Later developments followed, such as haloperidol in the late 1950s and various other agents, including the second-generation antipsychotics in the 1990s, but the initial availability happened in the mid-20th century.

The other timeframes don’t fit: early 19th century predates pharmacologic antipsychotics; 21st century reflects much later developments after the initial breakthrough; and late 20th century stagnation would miss the major advances that began in the 1950s and continued afterward.
