  1. ANTIPSYCHOTICS (also called neuroleptics, major tranquilizers)
    1. Typical antipsychotics:
      1. Phenothiazines(prochlorperazine [Compazine], promazine HCl [Sparine], chlorpromazine HCl [Thorazine], thioridazine [Mellaril], trifluoperazine HCl [Stelazine], perphenazine [Trilafon], triflupromazine HCl [Vesprin], fluphenazine enanthate [Prolixin]).
      2. Butyrophenones(haloperidol [Haldol, Serenace], droperidol fentanyl citrate [Innovar]).
      3. Thiothixenes(chlorprothixene [Taractan], thiothixene [Navane])—chemically related to phenothiazines, with similar therapeutic effects.
      4. Dibenzoxazepines—loxapine succinate [Loxitane])
    2. Atypical antipsychotics:
      1. Risperidone (Risperdal), olanzapine (Zyprexa), quetiapine (Seroquel), ziprasidone (Geodon).
        1. Use—incremental increases for first 3 days to manage psychotic symptoms. Effective for both positive and negative symptoms of schizophrenia. Risperidone also available as long-acting injection (Risperdal Consta): IM q 2 wk in alternate gluteal muscle site; delayed onset of action. Benefit: lower incidence of extrapyramidal symptoms.
        2. Assessment—side effects: same as for typical antipsychotics but with higher incidence of weight gain.
      2. Clozapine (Clozaril).
        1. Use—those who do not respond to other neuroleptic antipsychotic drugs; offers relief from schizophrenic symptoms: hallucinations, delusions, flat affect, apathy.
        2. Assessment—side effects:
          1. Most serious is agranulocytosis (potentially fatal; reversible if diagnosed within 1 to 2 weeks of onset).
            1. Symptoms of agranulocytosis: infection, high fever, chills, sore throat, malaise, ulceration of mucous membranes.
            2. Laboratory value: Discontinue drug with white blood cell (WBC) count less than 2,000 mcg/L or granulocyte count less than 1,000 mcg/L.
          2. Other side effects: seizures, tachycardia, orthostatic hypotension.
          3. Caution: must have weekly blood tests for WBC count; do not resume clozapine once it is discontinued, due to side effects.
    3. General use of antipsychotic medications—acute and chronic psychoses; most useful in cases of disorganization of thought or behavior; to decrease panic, fear, hostility, restlessness, aggression, and withdrawal.
    4. General assessment—side effects:

        1. Parkinsonism (also called pseudoparkinsonism)—tremors, cogwheel rigidity, shuffling gait, pill-rolling, masklike facies, salivation, and difficulty starting muscular movement (dyskinesia).
        2. Dystonia—limb and neck spasms (torticollis), extensive rigidity of back muscles (opisthotonos), oculogyric crisis, speech and swallowing difficulties, and protrusion of tongue.
        3. Akathisia—motor restlessness, pacing, foot tapping, inner tremulousness, and agitation.
        4. Tardive dyskinesia (TD)—excessive blinking; vermiform tongue movement; stereotyped, abnormal, involuntary sucking, chewing, licking, and pursing movements of tongue and mouth; grimacing, frowning, rocking.
          1. Cause—long-term use of high doses of antipsychotic drugs.
          2. Predisposing factors—age, women, organic brain syndrome (OBS); history of electroconvulsive therapy (ECT) or use of tricyclic antidepressants or anti-Parkinson drugs.
      3. Potentiates central nervous system depressants.
      4. Orthostatic hypotension (less with butyrophenones).
      5. Anticholinergic effects (atropine-like)—dry mouth, stuffy nose, blurred vision, urinary retention, and constipation.
      6. Pigmentary retinopathy—ocular changes (lens and corneal opacity).
      7. Photosensitivity.
      8. Weight gain (especially true of the atypical antipsychotic medications).
      9. Neuroleptic malignant syndrome (NMS):
        1. Description: a rare complication of antipsychotic drugs, with a rapid progression (1 to 3 days) and a 20% mortality rate. It is a serious medical emergency for which early recognition of symptoms is critical. Onset: at start, after change, or dose increase, when used with combination of medications.
