Sedation is a common effect of conventional antipsychotics, especially when they are taken at high doses. For example, the high-potency, low-dose atypical antipsychotic risperidone is less sedating than the lower-potency, high-dose atypical antipsychotics quetiapine and clozapine.What does risperidone do to the brain?
Risperidone is a medication that works in the brain to treat schizophrenia. It is also known as a second generation antipsychotic (SGA) or atypical antipsychotic. Risperidone rebalances dopamine and serotonin to improve thinking, mood, and behavior.When did second generation antipsychotics start?
First-generation antipsychotics (FGAs), also known as “typical antipsychotics,” were developed in the 1950s. Second-generation antipsychotics (SGAs), also known as “atypical antipsychotics,” emerged in the 1980s.What happens if a normal person takes antipsychotics?

Drugs called antipsychotics are the main treatment for schizophrenia. Typical examples of low-potency antipsychotic drugs are chlorpromazine, chlorprothixene, thioridazine or levomepromazine. High- and low-potency antipsychotics also seem to differ in their side-effects.What generation is chlorpromazine?
Chlorpromazine. What is chlorpromazine? First generation 'typical' antipsychotics such as chlorpromazine are an older class of antipsychotic than second generation 'atypical' antipsychotics.Why do antipsychotics cause EPS?
Antipsychotic medications commonly produce extrapyramidal symptoms as side effects. Extrapyramidal symptoms are caused by dopamine blockade or depletion in the basal ganglia; this lack of dopamine often mimics idiopathic pathologies of the extrapyramidal system.What are phenothiazine drugs?

By contrast, typical antipsychotics are more likely to cause Parkinson disease-like rigidity and spasticity (sometimes permanent).Is clozapine a phenothiazine?
The results confirmed that clozapine was an effective antipsychotic with no disabling neurological side-effects. They believed that if there are no Parkinsonian symptoms, the drug is not a true antipsychotic. The more pronounced the extrapyramidal symptoms were, the more effective the drug was.Which atypical antipsychotic drug has the lowest hypotensive effects?
Risperidone can occasionally cause orthostatic dizziness, hypotension including orthostatic hypotension, and reflex tachycardia. The least hypotensive effects are reported with ziprasidone.What is 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.
