Fluphenazine Brand Name– Prolixin | Prolixin Decanoate
What is Fluphenazine
Fluphenazine is a piperazine phenothiazine that is structurally similar to trifluoperazine, prochlorperazine, and perphenazine.
Fluphenazine is used to treat psychotic disorders and schizophrenia. A 2 mg dose of oral fluphenazine is roughly equivalent to 100 mg of chlorpromazine, the prototype antipsychotic.
Fluphenazine is most often used in patients that require depot therapy with a long-lasting injection.
Fluphenazine decanoate is a long-lasting intramuscular injection used for chronic schizophrenia or other chronic psychotic disorders. At steady-state (after 3 months on the same dose),
10 mg of fluphenazine decanoate injection given every 14 days would be equivalent to 100 mg of oral chlorpromazine given daily.
Fluphenazine enanthate, another intramuscular dosage form of fluphenazine, is rarely used clinically.
Fluphenazine was approved by the FDA in 1959.
