Second-generation antipsychotics work by blocking D2 dopamine receptors as well as serotonin receptor antagonist action. 5-HT2A subtype of serotonin receptor is most commonly involved.
What is the main difference between typical and atypical antipsychotics?
Typical antipsychotics and atypical antipsychotics are two different subtypes of antipsychotics which are often used in this field of psychiatry. The main difference between typical and atypical antipsychotics is the fact that atypical antipsychotics have fewer side effects than typical antipsychotics.
What is a second generation drug?
Second-generation antipsychotics (SGAs), also known as atypical antipsychotics, generally have lower risk of extrapyramidal side effects and tardive dyskinesia compared with first-generation antipsychotics (FGAs).

What are the differences between the first and second generation anticonvulsants?
The higher cost of second-generation AEDs compared with first-generation drugs is a major reason for their restriction from formularies. Data show that second generation AEDs have lower risk of teratogenesis and a more favorable side-effect profile compared with first-generation drugs.
What is the difference between SSRI and SNRI medications?
The main difference between SSRIs and SNRIs is that SSRIs prevent the reuptake of serotonin and SNRIs prevent the reuptake of serotonin and norepinephrine. Serotonin and norepinephrine are substances that the brain uses to send messages from one nerve cell to another.

Atypical antipsychotics are commonly referred to as second-generation antipsychotics, while typical psychotics are called first-generation antipsychotics.
