Psychotic Disorders Medications

Antipsychotic medications are the cornerstone of treatment for psychotic disorders such as schizophrenia, bipolar psychosis, and schizoaffective illness. They act primarily by modulating dopaminergic pathways, thereby reducing hallucinations, delusions, and thought disorganization. Clinicians prescribe these agents when patients exhibit persistent psychosis, functional decline, or risk of self-harm. The category includes first-generation (typical) agents that block dopamine D₂ receptors, second-generation (atypical) agents that combine dopamine antagonism with serotonin 5-HT₂A blockade, and long-acting injectable formulations that improve adherence. Selection depends on symptom profile, side-effect tolerance, previous response, and comorbid conditions. In Singapore, antipsychotics are prescription-only medicines, regulated by the Health Sciences Authority, and require ongoing clinical supervision.

Understanding Psychotic Disorders

Psychotic disorders encompass a spectrum of conditions marked by loss of reality testing, including schizophrenia, brief psychotic disorder, and psychotic features of bipolar disorder. The primary therapeutic goal is to achieve symptom remission, restore functional capacity, and prevent relapse. Antipsychotics intervene by dampening hyperactive dopaminergic transmission in mesolimbic pathways, while atypicals additionally address negative symptoms and cognitive deficits through serotonergic modulation. Regulatory frameworks classify these drugs as Schedule 4 (prescription-only) in Singapore, ensuring that a qualified psychiatrist or medical officer authorises each prescription. The category splits into several sub-domains: typical oral tablets, atypical oral agents, long-acting injectables (LAIs), and clozapine-specific protocols for treatment-resistant schizophrenia. Treatment philosophy emphasizes individualized dosing, gradual titration, and regular monitoring for metabolic, cardiac, and neurological adverse effects.

Common Medications in This Category

Major Therapeutic Subcategories

• First-Generation Antipsychotics (FGAs): Haloperidol, fluphenazine, and chlorpromazine block dopamine D₂ receptors strongly, producing robust antipsychotic effects but a higher risk of extrapyramidal symptoms (EPS) such as tremor and rigidity. They are useful when rapid sedation is needed or when patients have contraindications to atypicals.
• Second-Generation Antipsychotics (SGAs): Risperidone, olanzapine, quetiapine, and aripiprazole combine dopamine antagonism with serotonin 5-HT₂A blockade, offering lower EPS rates and effectiveness against negative symptoms. Metabolic side effects-including weight gain, dyslipidaemia, and glucose intolerance-are more common with certain SGAs.
• Long-Acting Injectable Antipsychotics (LAIs): Paliperidone palmitate, risperidone microspheres, and aripiprazole monohydrate provide sustained plasma levels for weeks to months, improving adherence in patients with unstable outpatient follow-up.
• Clozapine: Reserved for treatment-resistant schizophrenia, clozapine uniquely reduces suicidal behaviour but requires mandatory blood monitoring for agranulocytosis, myocarditis, and metabolic disturbances.
• Adjunctive Agents: Benztropine or diphenhydramine may be prescribed to counteract EPS, while lithium or valproate can augment antipsychotics in bipolar psychosis.

Treatment Considerations & Safety

Antipsychotic therapy demands close medical supervision. Baseline assessments should include fasting glucose, lipid profile, weight, and ECG, with follow-up monitoring every 3-6 months to detect metabolic shifts or cardiac QT prolongation. Drug interactions are common; for example, combining SGAs with strong CYP3A4 inhibitors can raise plasma levels, increasing sedation and orthostatic hypotension. Titration typically starts low and escalates slowly to the minimum effective dose, reducing the risk of EPS, akathisia, or sudden onset of sedation. LAIs require a loading dose and periodic injection site evaluation. Clozapine mandates weekly complete blood counts for the first six months, then bi-weekly thereafter. Patients should be educated about early signs of neuroleptic malignant syndrome, agranulocytosis, and severe weight gain, prompting immediate medical review.

Frequently Asked Questions

• What determines the choice between a typical and an atypical antipsychotic? Typical agents excel at controlling acute positive symptoms but carry higher EPS risk, whereas atypicals balance positive and negative symptom control with a lower tendency for motor side effects, albeit with metabolic considerations.

• How long should a patient remain on antipsychotic medication after remission? Maintenance therapy generally continues for at least one to two years after symptom remission, and often longer in chronic schizophrenia to prevent relapse.

• Can antipsychotics be taken with common over-the-counter supplements? Certain supplements, such as St. John’s wort or high-dose omega-3 fatty acids, may alter cytochrome P450 activity and affect antipsychotic levels. Discuss any supplement use with your prescriber before initiating therapy.

• Why are regular blood tests required for clozapine? Clozapine can cause agranulocytosis, a potentially life-threatening drop in white blood cells. Weekly blood counts detect this early, allowing prompt discontinuation if needed.

• Do long-acting injectables reduce the need for daily pills? Yes, LAIs release medication over weeks or months, improving adherence for patients who struggle with daily oral dosing, while providing steady plasma concentrations.

• What lifestyle adjustments support antipsychotic treatment? Maintaining a balanced diet, regular physical activity, and consistent sleep patterns can mitigate metabolic side effects and enhance overall mental health.

• Are there differences in side-effect profiles among second-generation agents? Olanzapine is strongly associated with weight gain, while ziprasidone has a lower metabolic impact but may prolong QT interval. Individual risk factors guide selection.

• How should a patient respond if they experience sudden dizziness after starting an antipsychotic? Dizziness can signal orthostatic hypotension, especially during dose escalation. Patients should rise slowly from seated positions and report persistent symptoms to their clinician.

• Is it safe to switch from one antipsychotic to another without a washout period? Cross-tapering is often employed to minimise withdrawal and rebound psychosis. Direct switches without supervision risk destabilisation and should only occur under professional guidance.

• Can antipsychotics be used during pregnancy? Some agents, such as haloperidol, have a longer safety record in pregnancy, whereas others carry higher teratogenic or neonatal adaptation risks. Decision-making must involve obstetric and psychiatric expertise.

• What should a patient do if a dose is missed? If a single oral dose is forgotten, take it as soon as remembered unless the next scheduled dose is near; then skip the missed dose and resume the regular schedule. Do not double-dose.
