Paliperidona Krka (Paliperidone)

Paliperidone is used in psychiatric care to manage psychotic disorders and related symptoms.

• Schizophrenia: Reduces hallucinations, delusions and thought disorder.
• Schizoaffective disorder: Controls both mood and psychotic symptoms.
• Maintenance therapy: Helps prevent relapse after an acute episode.

• Paliperidone acts as a dopamine D2 and serotonin 5‑HT2A receptor antagonist. By blocking D2 receptors in mesolimbic pathways it reduces positive psychotic symptoms, while 5‑HT2A antagonism modulates mood and negative symptom domains. The drug also has moderate affinity for α1‑adrenergic and histamine H1 receptors, contributing to its overall pharmacologic profile.

Paliperidone may cause a range of adverse reactions that vary in frequency and severity.

Common Side Effects

• Akathisia: Restlessness and an urge to move.
• Drowsiness: Feeling unusually sleepy.
• Weight gain: Increased appetite leading to weight increase.
• Dry mouth: Reduced salivation.
• Constipation: Decreased bowel motility.
• Elevated prolactin: Hormonal changes causing menstrual disturbances.

Serious or Rare Side Effects

• Neuroleptic malignant syndrome: Potentially life‑threatening reaction with fever and muscle rigidity.
• Tardive dyskinesia: Involuntary, repetitive movements.
• Seizures: Increased risk of convulsive episodes.
• Orthostatic hypotension: Marked drop in blood pressure on standing.
• Cardiac arrhythmias: QT‑interval prolongation.
• Severe hyperglycaemia: Marked increase in blood glucose levels.

Before initiating Paliperidona Krka, clinicians should evaluate patient history and monitor for specific safety concerns.

• Cardiovascular assessment: Check for history of arrhythmias or QT prolongation.
• Metabolic monitoring: Track weight, glucose and lipid profiles regularly.
• Prolactin levels: Observe for signs of hyperprolactinemia.
• CNS disorders: Use cautiously in patients with seizures or Parkinsonian features.
• Elderly patients: Start at lower doses and monitor for falls and sedation.
• Store below 25°C: Keep in the original packaging, protect from moisture and direct sunlight.

Paliperidone can interact with several medicines, affecting its efficacy or safety profile.

Major Interactions (Avoid)

• Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): Increase paliperidone exposure.
• Strong CYP3A4 inducers: Reduce the ​...
