title: Schizophrenia treatment. Critical review on the drugs and mechanisms of action of antipsychotics.
abstract: Schizophrenic treatment was developed during the second half of the last century, mainly within the context of the development of antipsychotic drugs. Even though there has been significant progress due to the availability and use of multiple drugs, these can still be classified into three basic groups of antipsychotic drugs (atypical antipsychotics, typical antipsychotics and dopamine partial agonist antipsychotics). Their primary antipsychotic mechanism is still the action on the dopamine systems. Many of the second-generation antipsychotics are believed to offer advantages over first-generation agents in the treatment for schizophrenia. However, the drug properties that provide the different therapeutic effects from those of the first generation are not clear and some adverse effects may still affect the patient's health and quality of life. Furthermore, the efficacy of the antipsychotics is limited. This has led to the use of adjuvant medications to strengthen the treatment effects. On the other hand, work is being done on the development of new research lines to develop new non-dopaminergic antipsychotic drugs, with not very successful results. The aim of this paper is to make a brief review on the current therapeutic armamentarium for schizophrenia, the strategies to develop drugs, and theories of mechanisms of action of antipsychotics. Emphasis is placed on the new therapeutic targets for the development of future treatments.
