Haloperidol is an antipsychotic medication used to treat certain psychiatric disorders. It belongs to the class of butyrophenone drugs that block dopamine receptors in the brain. By antagonizing d2 receptors it reduces excessive dopamine activity associated with psychosis. This action helps control hallucinations, delusions, and severe agitation. The drug also has sedative effects that contribute to its calming properties. Its therapeutic benefit arises from the combined reduction of positive symptoms of psychosis.

Haloperidol is an antipsychotic medication used primarily to manage symptoms of psychosis. It is classified as a butyrophenone derivative that works by blocking dopamine receptors in the brain. By selectively antagonizing d2 receptors it reduces excessive dopaminergic activity associated with hallucinations and delusions. This receptor blockade leads to a decrease in overstimulation of the mesolimbic pathway which helps alleviate psychotic manifestations. The drug also exhibits antiemetic and sedative properties through peripheral receptor interactions. Its long half-life allows for prolonged receptor occupancy which contributes to sustained symptom control. Clinically it is employed to treat severe agitation and to maintain stability in patients with chronic psychotic disorders.

Haloperidol is a typical antipsychotic medication used to treat certain mental health conditions. One common side effect is extrapyramidal symptoms, which can include muscle stiffness or involuntary movements. Patients may also experience sedation, leading to feelings of drowsiness or reduced alertness. Weight gain can occur due to changes in appetite and metabolism. Some individuals notice dry mouth, constipation, or blurred vision as part of the medication's impact. Increased heart rate is sometimes reported, though it is usually mild. In rare cases, the drug can cause hormonal changes such as irregular menstrual cycles or breast tenderness. Long-term use may require regular monitoring of blood levels and movement function.

Haloperidol can cause drowsiness and fatigue. It may lead to weight gain. Some individuals experience tremor or muscle stiffness. It can increase the risk of extrapyramidal symptoms. Sensitivity to sunlight may occur. Blood pressure changes are possible.
