Clozapine is a medication commonly used to treat schizophrenia and bipolar disorder. It is also known by several other names, including Clozaril, Azaleptin, Denzapine, and Leponex. While these names may sound different, they all refer to the same medication. In addition, there are several generic versions of clozapine available, such as FazaClo and Versacloz. All of these drugs work by blocking certain neurotransmitters in the brain to reduce symptoms of psychosis. While different names and versions of the drug may be used in different parts of the world, all of these medications are intended to treat the same conditions.
