Antipsychotics Classification and Indications

Quetiapine is categorized as a second-generation antipsychotic.

Nurses should advise patients taking antipsychotics to sip water frequently to counteract dry mouth, a common side effect.

Antipsychotics are specifically prescribed for conditions involving psychosis, such as schizophrenia. They are not used for major depression without psychotic features.

Haloperidol belongs to the first-generation (high potency) group of antipsychotics.

Patients on antipsychotics should get up slowly to prevent dizziness, a possible side effect.

Typical antipsychotics primarily work by blocking dopamine receptors, primarily targeting the dopamine system.

Patients taking antipsychotics should avoid extreme temperatures, as they can worsen side effects or lead to complications.

Hypersensitivity, or an allergic reaction to the drug, is a contraindication; meaning the medication should not be used in such cases.

MAOIs interact with tyramine-rich foods, leading to potentially dangerous reactions. Patients should avoid foods like aged cheese, cured meats, and fermented products.

Atypical antipsychotics go beyond just dopamine and also influence serotonin, norepinephrine, and histamine neurotransmission.
