Haldol decanoate (haloperidol)
Haldol decanoate injection contains the active ingredient haloperidol, which is a type of medicine called an antipsychotic. It is used in the treatment of various psychiatric illnesses.
When used in psychiatric illness, haloperidol is sometimes described as a neuroleptic or a 'major tranquilliser', though this last term is fairly misleading, as this type of medicine is not just a tranquilliser, and any tranquillising effect is not as important as the main way it works in psychiatric illness.
Haloperidol works by blocking a variety of receptors in the brain, particularly dopamine receptors. Dopamine is a natural compound called a neurotransmitter, and is involved in transmitting messages between brain cells. Dopamine is a neurotransmitter known to be involved in regulating mood and behaviour, amongst other things. Psychotic illness, and particularly schizophrenia, is considered to be caused by overactivity of dopamine in the brain. Haloperidol blocks the receptors that dopamine acts on and this prevents the overactivity of dopamine in the brain.
This helps to control psychotic illness. Haloperidol improves disturbed thoughts, feelings and behaviour in various mental conditions, including schizophrenia, mania, and behavioural disorders that involve aggression or severe agitation or excitement. It produces a calming effect and controls aggression, delusions and hallucinations. Haldol decanoate is a type of injection called a depot injection. It is administered into the muscle of the buttock, where it forms a reservoir of medicine that is slowly released into the bloodstream over a period of four weeks.
