What is the difference between typical and atypical antipsychotics?
Typical antipsychotic drugs act on the dopaminergic system, blocking the dopamine type 2 (D2) receptors. Atypical antipsychotics have lower affinity and occupancy for the dopaminergic receptors, and a high degree of occupancy of the serotoninergic receptors 5-HT2A.

Can you take 2 antipsychotics?
Might I need to take two antipsychotics at once? Prescribing more than one antipsychotic drug at the same time is called polypharmacy. In most cases doctors should avoid doing this, except in specific short-term situations. For example, this may happen while you are switching from one antipsychotic drug to another.
Do antipsychotics block dopamine?
Generally speaking, antipsychotic medications work by blocking a specific subtype of the dopamine receptor, referred to as the D2 receptor. Older antipsychotics, known as conventional antipsychotics, block the D2 receptor and improve positive symptoms.
