The decanoate ester of haloperidol (haloperidol decanoate, trade names Haldol decanoate, Halomonth, Neoperidole) has a much longer duration of action, so is often used in people known to be noncompliant with oral medication. A dose is given by intramuscular injection once every two to four weeks. [38]
Haloperidol decanoate is provided in the form of 50 or 100 mg/mL oil solution of sesame oil and benzyl alcohol in ampoules or pre-filled syringes. [ 6 ] [ 7 ] [ 9 ] Its elimination half-life after multiple doses is 21 days.
A correlation exists between average clinical potency and affinity of the antipsychotics for dopamine receptors. [50] Chlorpromazine tends to have a greater effect at serotonin receptors than at D2 receptors, which is notably the opposite effect of the other typical antipsychotics.
For reference, the typical antipsychotic haloperidol tends to block about 80% of D2 receptors at doses ranging from 2 to 5 mg per day. [5] On the aggregate level, no typical antipsychotic is more effective than any other, though people will vary in which antipsychotic they prefer to take based on individual differences in tolerability and ...
There have also been substantial price rises. Risperidone 6 mg tablets, the largest, increased from £3.09 in July 2017 to £41.16 in June 2022. The NHS is spending an additional £33 million annually on antipsychotics. Haloperidol 500 microgram tablets constituted £14.3 million of this. [289]

Haloperidol binds D 2, D 3 and D 4 with the highest affinity, but also binds D 1 and D 5. [1] [2] [3] Haloperidol also has a risk for QTc prolongation. [17] Fluphenazine binds D 2 and D 3 with the highest affinity but D 1 and D 5 as well [1] [2] Flupentixol binds D 1, D 2, D 3, and D 5 [2] and is also used as an antidepressant. [1] Fluspirilene ...
