- Summary
Pimozide is an antipsychotic used to manage debilitating motor and phonic tics in patients with Tourette's Disorder.
- Brand Names
- Orap
- Generic Name
- Pimozide
- DrugBank Accession Number
- DB01100
- Background
A diphenylbutylpiperidine that is effective as an antipsychotic agent and as an alternative to haloperidol for the suppression of vocal and motor tics in patients with Tourette syndrome. Although the precise mechanism of action is unknown, blockade of postsynaptic dopamine receptors has been postulated. (From AMA Drug Evaluations Annual, 1994, p403)

Pimozide is an orally active antipsychotic drug product which shares with other antipsychotics the ability to blockade dopaminergic receptors on neurons in the central nervous system. However, receptor blockade is often accompanied by a series of secondary alterations in central dopamine metabolism and function which may contribute to both pimozide's therapeutic and untoward effects. In addition, pimozide, in common with other antipsychotic drugs, has various effects on other central nervous system receptor systems which are not fully characterized. Pimozide also has less potential for inducing sedation and hypotension as it has more specific dopamine receptor blocking activity than other neuroleptic agents (and is therefore a suitable alternative to haloperidol).
- Mechanism of action
The ability of pimozide to suppress motor and phonic tics in Tourette's Disorder is thought to be primarily a function of its dopaminergic blocking activity. Pimozide binds and inhibits the dopamine D2 receptor in the CNS.
