Atypical antipsychotics, such as clozapine block both the D2 Dopamine receptors as well as 5HT2A serotonin receptors. Atypical antipsychotics are favored over conventional antipsychotics because they reduce the prevalence of pseudoparkinsonism which causes tremors and muscular rigidity similar to Parkinson's disease.
The atypical antipsychotics (AAP), also known as second generation antipsychotics (SGAs) and serotonin–dopamine antagonists (SDAs), [1] [2] are a group of antipsychotic drugs (antipsychotic drugs in general are also known as tranquilizers and neuroleptics, although the latter is usually reserved for the typical antipsychotics) largely introduced after the 1970s and used to treat psychiatric ...
Bipolar disorder (acute mania and mixed episodes) may be treated with either typical or atypical antipsychotics, although atypical antipsychotics are usually preferred because they tend to have more favourable adverse effect profiles [16] and, according to a recent meta-analysis, they tend to have a lower liability for causing conversion from ...
Find out what typical and atypical antipsychotics are, what they are used for, how they work, and their potential risks and benefits.
Both typical and atypical antipsychotics can cause tardive dyskinesia. [50] According to one study, rates are lower with the atypicals at 3.9% as opposed to the typicals at 5.5%. [ 50 ] Although quetiapine and clozapine are atypical antipsychotics, switching to these atypicals is an option to minimize symptoms of tardive dyskinesia caused by ...
Second-generation (atypical) antipsychotics: The concept of "atypicality" is from the finding that second generation antipsychotics (SGAs) have a greater serotonin/dopamine ratio than earlier drugs, and might be associated with improved efficacy (particularly for the negative symptoms of psychosis) and reduced extrapyramidal side effects.
Antipsychotics are sometimes referred to as neuroleptic drugs and some antipsychotics are branded "major tranquilizers". There are two categories of antipsychotics: typical antipsychotics and atypical antipsychotics. Most antipsychotics are available only by prescription. Common antipsychotics:
Typical antipsychotics (also known as major tranquilizers, and first generation antipsychotics) are a class of antipsychotic drugs first developed in the 1950s and used to treat psychosis (in particular, schizophrenia). Typical antipsychotics may also be used for the treatment of acute mania, agitation, and other conditions.
