Final answer:
Haloperidol is a first-generation antipsychotic, and other drugs in this class don't share a standard suffix in their names. Examples include Trazodone, etoperidone, lorpiprazole, mepiprazol, and nefazodone. Risperidone, a drug from 1994, antagonizes D2 and serotonin type 2 receptors and is considered a second-generation antipsychotic.
Step-by-step explanation:
The drug Haloperidol is a classic antipsychotic medication used in the treatment of schizophrenia and is one of the first-generation antipsychotics. When looking at suffixes for other first-generation antipsychotic drugs, there isn't a uniform suffix that they all share.
However, some examples of other first-generation antipsychotics include drugs like Trazodone (Desyrel), etoperidone (Axiomin), lorpiprazole (Normarex), mepiprazol (Psigodal), and nefazodone (Serzone). Each of these drugs has distinct chemical structures and branding, yet they all share the property of modulating neurotransmitter systems in the brain. In 1994, a newer antipsychotic, risperidone (Risperdal), was introduced which antagonizes D2 (dopamine type 2) and serotonin type 2 receptors, offering a different pharmacological profile hence categorized as a second-generation antipsychotic.
