How was schizophrenia treated in the 1950s?
The early 20th century treatments for schizophrenia included insulin coma, metrazol shock, electro-convulsive therapy, and frontal leukotomy. Neuroleptic medications were first used in the early 1950s.
What are the third generation antipsychotics?
Aripiprazole as the third generation antipsychotic prototype. Aripiprazole is a relatively new approved antipsychotic drug proffered by its developers as a high affinity, low intrinsic activity partial D2 agonist.
What is a second generation antipsychotic?
Second-generation antipsychotics (SGAs), also known as atypical antipsychotics, generally have lower risk of extrapyramidal side effects and tardive dyskinesia compared with first-generation antipsychotics (FGAs).
Is Risperdal a first generation antipsychotic?
Risperidone (15970) Risperidone (7.2. 1) (Risperdal) is the first second-generation antipsychotic that was specifically designed as a combined D2 and serotonin 5-HT(2A) receptor antagonist, thus following the pharmacological mechanism thought to be responsible for the antipsychotic effects.
