The first LAI antipsychotics (often referred to as simply "LAIs") were the typical antipsychotics fluphenazine and haloperidol. [18] Both fluphenazile and haloperidol are formulated as decanoates, referring to the attachment of a decanoic acid group to the antipsychotic molecule. [18] These are then dissolved in an organic oil. [18]

Dopamine receptor flow chart. Dopamine receptors are all G protein–coupled receptors, and are divided into two classes based on which G-protein they are coupled to. [1] The D 1-like class of dopamine receptors is coupled to Gα s/olf and stimulates adenylate cyclase production, whereas the D 2-like class is coupled to Gα i/o and thus inhibits adenylate cyclase production.
