Identification
- Summary
Melperone is an atypical butyrophenone antipsychotic used to treat sleep disorders, confusion, and psychomotor dysfunction associated with geriatric, psychiatric, and alcohol-dependent patients.
- Generic Name
- Melperone
- DrugBank Accession Number
- DB09224
- Background
Melperone is an atypical antipsychotic of the butyrophenone chemical class, making it structurally related to the typical antipsychotic haloperidol. Melperone has been used for a span of greater than 30 years in the European Union 5. It has been well established in the treatment of confusion, anxiety, restlessness (particularly in the elderly) and schizophrenia as It is known to be well-tolerated with an excellent safety profile. Recently, it has been studied as a treatment of psychosis related to Parkinson's disease 5.

Melperone has been demonstrated to produce an antipsychotic effect at doses that cause minimal extrapyramidal symptoms frequently associated with more traditional antipsychotics 6,8.
- Mechanism of action
Melperone demonstrates antagonist activity at D2 dopaminergic and 5HT2A serotonergic receptors 8. It has a weak affinity to D2 receptors and possesses less risk of inducing dopamine receptor supersensitivity after both acute and chronic administration [L3146]. In addition, the ratio of dopamine D4/D2 occupancy for melperone has been shown to resemble the binding profile of clozapine 9.
Target Actions Organism ADopamine D2 receptor antagonistHumans - Absorption
Oral doses are rapidly absorbed (Tmax 1.5–3.0 hours post oral ingestion)[A3145].
- Volume of distribution
Not Available
- Protein binding
Melperone has a bioavailability of 50-70% [A3145].
- Metabolism
Mainly hepatic 11.
- Route of elimination
Excreted mainly in the urine, with small amounts of unchanged drug 11.
- Half-life
Approximately 3-4 hours after oral administration 1. After intramuscular injection, the half-life has been found to be approximately 6 hours 1.

Drug Interaction Integrate drug-drug
interactions in your software1,2-Benzodiazepine The risk or severity of adverse effects can be increased when Melperone is combined with 1,2-Benzodiazepine. Abacavir Abacavir may decrease the excretion rate of Melperone which could result in a higher serum level. Acebutolol Acebutolol may increase the arrhythmogenic activities of Melperone. Aceclofenac Aceclofenac may decrease the excretion rate of Melperone which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Melperone which could result in a higher serum level. Acetaminophen The metabolism of Acetaminophen can be decreased when combined with Melperone. Acetazolamide The risk or severity of adverse effects can be increased when Acetazolamide is combined with Melperone. Acetophenazine The risk or severity of adverse effects can be increased when Acetophenazine is combined with Melperone. Acetyldigitoxin Acetyldigitoxin may increase the arrhythmogenic activities of Melperone. Acetylsalicylic acid Acetylsalicylic acid may decrease the excretion rate of Melperone which could result in a higher serum level.
