Clozapina: una revisión

Schizophrenia is a psychiatric disorder that is the paradigm of mental illness. Its treatment remains a controversial issue, especially as regards side effects, remission of symptoms, function, and the quality of life of the individual who suffers from it. Clozapine, since its introduction in 1959, and its formal acceptance by the FDA for treatment resistant schizophrenia in 1990, is the drug that has led to most controversy, due to its atypical profile action at multiple receptors. These actions determine the side effects (e.g., hyper-salivation, sedation), and although not placing the integrity of the patient at risk, can be a threat to their quality of life. There are other side effects that can, in themselves, endanger the patient's life (e.g., agranulocytosis, myocarditis). However, the knowledge of the molecule, its indications for use, as well as mandatory monitoring, are actions that allow the safe use of the substance that can benefit the patients, and therefore their families. This is mainly due to the therapeutic action not only improving the positive and negative psychotic symptoms, but also its significant effect on suicidality and aggressiveness, which is greater than other antipsychotics. It can also be used in patients with concomitant diseases, such as Parkinson's disease, and tardive dyskinesia.
