Description
Curator's Comment:: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/10372606

Clozapine was discovered in 1958 by an anesthetist and now it is used for the treatment of schizophrenia. Although the exact mechanism of its action is unknown, the effect of clozapine on schizophrenia is associated with inhibition of dopamine D2 and serotonin 2A receptors.

Sample Use Guides

Start with 12.5 mg once daily or twice daily, then increase the total daily dosage in increments of 25 mg to 50 mg per day (if well-tolerated) in order to reach 300 mg to 450 mg per day, in divided doses, by the end of 2 weeks.
Route of Administration: Oral
The effects of antipsychotic medication on the energy metabolism of OLN-93 cells were analyzed by adding a vehicle (0.01% HCl, same dissolving solution used to solubilize the antipsychotics), 1 or 10 ug/ml of clozapine to the cell culture for 6 or 24 h.
