Blonanserin
Uses of Blonanserin
Blonanserin is an atypical antipsychotic medicine used to manage schizophrenia and related psychotic conditions. It helps reduce the symptoms that affect thinking, perception, and behaviour.
Blonanserin is commonly used for:
• Schizophrenia: Reduces positive symptoms such as hallucinations (hearing or seeing things that are not there) and delusions (fixed false beliefs), as well as negative symptoms such as emotional withdrawal, reduced motivation, and difficulty with social interaction.
• Other psychotic disorders: Used in the management of other conditions involving psychosis, where a doctor determines it to be appropriate.
• Treatment-resistant schizophrenia: May be considered in some patients who have not responded adequately to other antipsychotic medicines, under specialist supervision.

How Blonanserin works
- Blonanserin works by blocking specific chemical receptors in the brain that are involved in regulating mood, perception, and behaviour.
- It primarily targets two types of receptors: dopamine D2 receptors and serotonin 5-HT2A receptors. In schizophrenia, an imbalance in dopamine and serotonin activity in different areas of the brain contributes to the symptoms of the condition. By blocking D2 receptors, Blonanserin reduces the excessive dopamine activity associated with hallucinations and delusions. By also blocking 5-HT2A receptors, it helps modulate dopamine release in certain brain areas, which may improve negative symptoms and reduce the risk of movement-related side effects compared to older antipsychotics that target only dopamine receptors.
- This dual receptor-blocking profile is what distinguishes Blonanserin as an atypical (second-generation) antipsychotic.

Overdose and Missed Dose
- Taking more than the prescribed dose of Blonanserin may cause serious symptoms including excessive sedation, a significant drop in blood pressure (hypotension), involuntary muscle movements (extrapyramidal reactions), and abnormal heart rhythm (QT prolongation). These require prompt medical attention. If an overdose is suspected, seek emergency medical help immediately.
If you miss a dose of Blonanserin, take it as soon as you remember. If it is nearly time for your next dose, skip the missed one and continue with your regular schedule. Do not take two doses at the same time to make up for a missed one. Do not stop taking Blonanserin without consulting your doctor.

Most side effects are temporary and generally harmless and resolve when discontinuing this medicine. However, if you experience any severe side effects or worsening of any of the symptoms, please consult your doctor.
To manage side effects such as constipation, it may help to drink plenty of fluids and consume dietary fibre.
If experiencing insomnia or sedation, adjusting the timing of the dose could potentially help mitigate these effects.
