Which medication is known as a long-acting antipsychotic?

• A. Fluphenazine decanoate
• B. Pimozide
• C. Chlorpromazine
• D. Haloperidol

Answer: (A)

Fluphenazine decanoate is classified as a long-acting antipsychotic due to its formulation that allows for extended intervals between doses. This medication is administered via intramuscular injection and is designed to release the active ingredient slowly into the bloodstream over a prolonged period, typically ranging from two to four weeks. This characteristic is particularly beneficial for individuals who may have difficulty adhering to a daily oral medication regimen, improving patient compliance and ensuring more consistent therapeutic levels. In contrast, the other medications listed are not considered long-acting. Pimozide, chlorpromazine, and haloperidol can all be used to treat various psychiatric disorders but typically require more frequent dosing when taken orally. While haloperidol is available in a long-acting injectable form, the specific mention of fluphenazine decanoate highlights its established role and classification as a long-acting antipsychotic.
