Uses

Fluphenazine Decanoate is used in psychotropic drug treatments like those relating to schizophrenia. Antipsychotic.

Definition

ChEBI: Fluphenazine decanoate is the prodrug of fluphenazine, an antipsychotic drug used for the symptomatic management of psychosis in patients with schizophrenia. It has a role as a phenothiazine antipsychotic drug, a prodrug and a dopaminergic antagonist. It is a member of phenothiazines, a decanoate ester, an organofluorine compound and a N-alkylpiperazine. It is functionally related to a fluphenazine.

Clinical Use

Antipsychotic
Schizophrenia and other psychoses

Drug interactions

Potentially hazardous interactions with other drugs
Anaesthetics: enhanced hypotensive effect.
Analgesics: increased risk of convulsions with tramadol; enhanced hypotensive and sedative effects with opioids.
Anti-arrhythmics: increased risk of ventricular arrhythmias with anti-arrhythmics that prolong the QT interval; increased risk of ventricular arrhythmias with amiodarone and dronedarone - avoid; increased risk of ventricular arrhythmias with disopyramide.
Antibacterials: increased risk of ventricular arrhythmias with delamanid and moxifloxacin - avoid
Antidepressants: increased risk of ventricular arrhythmias with tricyclics, citalopram, escitalopram; possible increased risk of convulsions with vortioxetine
Antiepileptics: antagonises anticonvulsant effect.
Antimalarials: increased risk of ventricular arrhythmias with artenimol with piperaquine and artemether/lumefantrine - avoid.
Antipsychotics: increased risk of ventricular arrhythmias with droperidol, pimozide and risperidone - avoid; avoid use of depot formulations with clozapine (cannot be withdrawn quickly if neutropenia occurs).
Antivirals: increased risk of ventricular arrhythmias with saquinavir - avoid; concentration possibly increased with ritonavir.
Anxiolytics and hypnotics: increased sedative effects
Atomoxetine: increased risk of ventricular arrhythmias.
Beta-blockers: enhanced hypotensive effect; increased risk of ventricular arrhythmias with sotalol
Cytotoxics: increased risk of ventricular arrhythmias with arsenic trioxide
Diuretics: enhanced hypotensive effect.
Lithium: increased risk of extrapyramidal side effects and possibly neurotoxicity.
Pentamidine: increased risk of ventricular arrhythmias - avoid.
Avoid with drugs that prolong the QT interval.

Metabolism

The cytochrome P450 isoenzyme CYP2D6 is involved in fluphenazine metabolism.
