Fluphenazine Decanoate Injection

Fluphenazine Decanoate Injection is a long-acting injectable (LAI) antipsychotic formulation containing fluphenazine decanoate, a depot ester of fluphenazine. It belongs to the phenothiazine class of first-generation antipsychotics and is administered by deep intramuscular injection.

It is primarily used for the maintenance treatment of schizophrenia and other chronic psychotic disorders, particularly when long-term antipsychotic therapy is required. The decanoate formulation provides a prolonged therapeutic effect, allowing administration at extended intervals compared with oral formulations.
