Gencate Depot (25Mg) 1Ml, 1 Injection

Fluphenazine, a typical antipsychotic medication, exerts its therapeutic effects primarily by antagonizing dopamine receptors, particularly the D2 subtype. This mechanism is central to its clinical utility in managing psychotic disorders. By blocking dopamine receptors in the brain, especially in areas like the mesolimbic and mesocortical pathways, fluphenazine helps to regulate dopamine signaling. This modulation plays a crucial role in alleviating symptoms associated with psychosis, such as hallucinations, delusions, and disorganized thinking. The selective action on dopamine receptors underpins the drug's effectiveness in treating these symptoms, contributing to its place as a significant pharmacological tool in psychiatry.

Following are the drug interactions for Fluphenazine 25mg Injection:

• Concurrent use with central nervous system (CNS) depressants (e.g., benzodiazepines, opioids, alcohol) may enhance sedation, respiratory depression, and drowsiness.
• Combining with other antipsychotics or dopamine-blocking agents (e.g., haloperidol, risperidone, metoclopramide) may increase the risk of extrapyramidal symptoms (EPS) and tardive dyskinesia.
• Concurrent use with antihypertensive medications (e.g., beta-blockers, ACE inhibitors) may cause excessive blood pressure lowering, leading to dizziness or fainting.
• Combining with medications that prolong the QT interval (e.g., amiodarone, erythromycin, quinidine) may increase the risk of serious heart arrhythmias.
• Fluphenazine may reduce the effectiveness of dopamine agonists (e.g., levodopa, pramipexole) used in Parkinson’s disease, worsening symptoms.
• Concurrent use with anticholinergic drugs (e.g., atropine, oxybutynin) may increase the risk of dry mouth, constipation, urinary retention, and blurred vision.
• Co-administration with serotonergic drugs (e.g., SSRIs, SNRIs, tramadol) may increase the risk of serotonin syndrome.
• Fluphenazine may interact with lithium, increasing the risk of neurotoxicity, manifesting as confusion, tremors, or muscle rigidity.
• Concurrent use with CYP2D6 inhibitors (e.g., fluoxetine, paroxetine) may increase fluphenazine levels, leading to a higher risk of side effects.
• Using fluphenazine with strong enzyme inducers (e.g., carbamazepine, rifampin) may decrease its effectiveness by increasing its metabolism.
