Presymptomatic and prodromal treatments for schizophrenia: putting the cart before the horse or preventing disease progression? This chapter will explore antipsychotic drugs, with an emphasis on treatments for schizophrenia.
These treatments include not only conventional antipsychotic drugs, but also the newer atypical antipsychotic drugs that have largely replaced the older conventional agents. Qualitative and semi-quantitative representation of receptor binding properties. Throughout this chapter, the receptor binding properties of the atypical antipsychotics are represented both graphically and semi-quantitatively. Each drug is represented as a blue sphere, with its most potent binding properties depicted along the outer edge of the sphere. Additionally, each drug has a series of colored boxes associated with it. Antipsychotic drugs exhibit possibly the most complex pharmacologic mechanisms of any drug class within the field of clinical psychopharmacology.
In this section we will discuss the pharmacologic properties of the first drugs that were proven to effectively treat schizophrenia. A list of many conventional antipsychotic drugs is given in Table 5-1. 60 years ago, rather than from scientific knowledge of the neurobiological basis of psychosis, or of the mechanism of action of effective antipsychotic agents. Chlorpromazine indeed has antihistaminic activity, but its therapeutic actions in schizophrenia are not mediated by this property. Conventional antipsychotics, also called first-generation antipsychotics or typical antipsychotics, share the primary pharmacological property of D2 antagonism, which is responsible not only for their antipsychotic efficacy but also for many of their side effects.

Shown here is an icon representing this single pharmacological action. Mesolimbic dopamine pathway and D2 antagonists. In untreated schizophrenia, the mesolimbic dopamine pathway is hypothesized to be hyperactive, indicated here by the pathway appearing red as well as by the excess dopamine in the synapse. This leads to positive symptoms such as delusions and hallucinations. Hypothetical thresholds for conventional antipsychotic drug effects. Mesocortical dopamine pathway and D2 antagonists.
Nigrostriatal dopamine pathway and D2 antagonists. The nigrostriatal dopamine pathway is theoretically unaffected in untreated schizophrenia. However, if D2 receptor blockade is removed early enough, tardive dyskinesia may reverse. D2 receptors by an appropriate decrease in the number or sensitivity of them in the nigrostriatal pathway once the antipsychotic drug that had been blocking these receptors is removed.
