Medication Recommendation for Psychosis – Schizophrenia (Short Version)​

Status as of: Aug 01, 2025

Overview​

This treatment approach combines the intermittent use of an atypical antipsychotic (preferably Aripiprazole) with the daily administration of Bupropion, a SNDRI antidepressant. The goal is not only to manage positive symptoms, but especially to improve negative symptoms and cognitive functioning (e.g., working memory, attention, executive control).

Benefits and Use of Bupropion and Aripiprazole in Interval Therapy (Short Summary)

• Bupropion enhances alertness, focus, and mental clarity → significantly lowers the risk of delusions by enabling more reflective processing of psychotic triggers.
• During aripiprazole-free intervals, bupropion reduces irritability and inner restlessness — symptoms often reappear only after several months.
• Particularly effective against negative symptoms like slowed thinking and lack of motivation.
• Ideal for individuals with strong self-awareness or insight into their condition.

Positioning Interval Therapy within the Treatment Pathway

• Conventional antipsychotics (e.g. risperidone or depot formulations) are useful in the acute phase.
• Transitioning to activating agents like aripiprazole or cariprazine improves tolerability and motivation.
• Aripiprazole is highly suitable for interval treatment: even 5 mg can suffice for stabilization.
• Interval therapy offers hope: many patients on long-term medication experience relapses or stop treatment.
• Monotherapy is recommended — mild residual symptoms may even help foster self-reflection.

Conceptual Framework

• Complete symptom suppression is unrealistic — some symptoms (e.g. paranoid fears) reflect real inner conflicts.
• Interval therapy creates space for controlled engagement with psychotic experiences.
• Goal: more autonomy, with prospects for part-time work and social reintegration during stable phases.

Core Components of the Strategy​

1. Intermittent Use of Aripiprazole​

• Taken for approx. 1–3 weeks during early warning symptoms, followed by a pause of 2 to 6 months
• Goal: Short-term symptom control – especially stabilization of positive symptoms
• After discontinuation: notable improvement in negative symptoms and cognition (in combination with Bupropion)
• Aripiprazole should be reintroduced briefly if symptoms begin to worsen

Important: Since Bupropion is a CYP2D6 inhibitor, Aripiprazole blood levels may rise by approx. 40–80% – dose adjustment is advised. Therapeutic drug monitoring (TDM) is recommended.

2. Continuous Intake of Bupropion (SNDRI)​

• Dosage: 300–450 mg daily (gradual titration recommended)
• Effects:
  • Enhances cognition and reduces negative symptoms
  • Calms inner agitation, irritability, and mood swings
  • Supports smoking cessation through dopamine effects
• Limitation: Its effectiveness decreases after approx. 4–6 months → Aripiprazole needs to be reintroduced to maintain stability

Note: Bupropion is not effective against addictions such as alcohol, gambling, or compulsive shopping – additional support is needed in those cases.

3. Adjunctive Therapy During Intervals​

SSRI Antidepressants (Citalopram, Sertraline or Escitalopram)

• Regulate emotional reactivity and libido
• Improve depressive symptoms
• Help with urinary retention or constipation potentially caused by Bupropion

May cause restlessness during transition → Bupropion should be stabilized first

Tricyclic Antidepressants or SARI (Trimipramine drops or Trazodone)

• Trimipramine: strongly sedating, may cause daytime fatigue
• Trazodone: gentler, less residual sedation
• Used for sleep disturbances and addiction prevention, especially in activated phases with elevated drive (“reborn feeling”)

SARI (Trazodone) as an Alternative or Addition to SSRI

• For isolated sleep disturbances, 100 mg of Trazodone in the evening is typically sufficient.
• At higher doses (200–300 mg), Trazodone exhibits mild to moderate SSRI-like effects and may substitute for a conventional SSRI in some cases.
• Due to overlapping serotonergic mechanisms, combining SSRI + Trazodone should only be considered under strict clinical monitoring, especially in psychotic disorders, to reduce the risk of serotonin syndrome and unpredictable interactions.

Comparison of SERT Reuptake Inhibition:

Ki = inhibition constant; lower value = higher binding potency SERT Occupancy = percentage of serotonin transporters blocked in vivo

4. Addiction Risk and Prevention​

• Antipsychotic-free interval phases often come with increased drive and a “reborn feeling” → elevates risk for alcohol, gambling, and shopping addiction
• Even brief use of Aripiprazole can trigger compulsive behavior in some cases
• Trimipramine or Trazodone can be protective, optionally combined with Naltrexone
• Bupropion is especially effective in treating nicotine dependence, as it reduces craving via dopamine & noradrenaline reuptake inhibition

5. Nutritional Supplementation​

• Vitamin B6 (50–300 mg/day): alleviates inner agitation and may reduce akathisia
• Magnesium & B-complex vitamins: support general stability and nervous system balance
• Niacin (Vitamin B3): improves circulation and may provide neurobiological benefits

At higher doses (400–1200 mg/day), B6 requires medical supervision – above 200 mg, there's risk of peripheral neuropathy

Dosage Adjustment & Drug Interactions​

Bupropion is a moderate CYP2D6 inhibitor, which can impact Aripiprazole metabolism:

Recommendation: One-time TDM (Therapeutic Drug Monitoring) for personalized dose adjustment when used in combination.

Therapeutic Concept Summary​

This patient-led approach provides a framework for long-term stabilization based on:

• Short-term use of Aripiprazole to manage positive symptoms
• Ongoing Bupropion intake to support cognition and motivation
• Adjunctive medications to address sleep, emotional sensitivity, and addiction risks
• Supplements to aid in calming and physiological support

Goal: Achieving as normal a daily life as possible, with reduced medication load and targeted interventions instead of continuous antipsychotic use.
