How Haloperidol Tablet Works

The science behind haloperidol's effectiveness lies in its unique interaction with the brain's chemical messaging system. This medication belongs to the butyrophenone family and works primarily by affecting how the brain processes certain chemicals. Haloperidol's main action comes from its strong ability to block dopamine receptors, particularly the D2 type, in specific areas of the brain called the mesolimbic and mesocortical systems. This blocking action helps control symptoms associated with conditions like schizophrenia.

The medication affects several brain receptors:

• Strong blocking effect on D2 dopamine receptors
• Moderate effect on 5-HT2 receptors
• Limited impact on D1 dopamine receptors
• Minimal effect on histamine H1 receptors

• Opioid medicines
• Other antipsychotic medications
• Rifampin
• Ritonavir
• Selective serotonin reuptake inhibitors (SSRIs) like fluoxetine, paroxetine, or sertraline
