Risperidone, also known as Risperdal, is an atypical antipsychotic medication of the benzisoxazole chemical class. Risperidone is prescribed for bipolar disorder, autism, and psychotic disorders, such as in schizophrenia. It is sometimes used as a sedative to reduce the effects of psychedelics like LSD and to induce sleepiness. Benzodiazepines are also used for this purpose.

Pharmacology

Risperidone has a quite complex pharmacology, but its main mechanism of action is that it is a D2 dopaminergic receptor antagonist, meaning it blocks dopamine from binding to the receptor, meanwhile not activating it. [citation needed] It also blocks most of the serotonin receptors, being an inverse agonist at the 5-HT2A, 5-HT2B, and 5-HT2C serotonin receptors.[citation needed] Risperidone has the strongest affinity to the 5-HT2A receptor.[citation needed] On top of that, it acts as an irreversible antagonist at the 5-HT7 serotonin receptor. Its hypnotic effects come from the blockade of dopamine D2 receptors.

Subjective effects

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.

It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.
