treat positive AND negative sx | risperidone, clozapine, olanzapine, quetiapine
43
risperidone
blocks serotonin and dopamine in the CNS caution with immunosuppressive medications, opioids, alcohol, levodopa, tricyclic antidepressants, clarithromycin, barbiturates avoid with pregnancy & lactation, bone marrow suppression
44
risperidone side effects
can cause metabolic syndrome, orthostatic hypotension, anticholinergic symptoms, agitation, dizziness, mild EPS, elevated prolactin, sexual dysfunction
45
clozapine (clozaril)
atypical antipsychotic reduces dopamine in CNS caution with bone marrow depression, Parkinson disease, lactation avoid use with antihypertensives, CNS depressants, levodopa, lithium, other anticholinergic drugs
46
clozapine (clozaril) adverse effects
can cause agranulocytosis (highest risk of any psych med), seizures!, neuroleptic malignant syndrome, ventricular arrhythmias, type 2 diabetes, anticholinergic side effects, orthostatic hypotension caffeine increases side effects
47
clozapine (clozaril) nursing interventions
periodic WBC counts WBC is ≤3000, hold drug. If WBC is ≤1500 d/c monitor BP ↓↑ and change positions slowly give with food or milk
48
olanzapine (zyprexa)
atypical antipsychotic/mood stabilizer antagonizes dopamine and serotonin in the CNS caution with phenylketonuria, lactation avoid use with antihypertensives, CNS depressants, levodopa, nicotine, fluvoxamine
49
olanzapine (zyprexa) adverse effects
agranulocytosis, seizures, neuroleptic malignant syndrome, drug reaction with eosinophilia, type 2 diabetes, anticholinergic side effects, orthostatic hypotension
50
olanzapine (zyprexa) interventions
monitor BP ↓↑, monitor for side effects, observe for cheeking, assess for falls
51
third-gen antipsychotics | serotonin-dopamine activity monitors
developed to control for the side effects of the other classes of antipsychotic medications and still be effective in dealing with both positive and negative symptoms of schizophrenia aripiprazole (abilify), cariprazine, lumateperone
52
cariprazine (vraylar)
third gen antipsychotic stabilizes dopamine to reduce antipsychotic symptoms caution with lactation, third trimester pregnancy avoid use with diuretics, antihypertensives
53
cariprazine (vraylar) adverse effects
Stevens Johnson, agranulocytosis, neuroleptic malignant syndrome, drowsiness, blurred vision, headache, dyspepsia, orthostatic hypotension, akathesia, constipation
54
cariprazine (vraylar) interventions
``` assess mental status watch for cheeking administer with or without meals assess for rash monitor BP ↑↓ ```
55
anticholinergic effects
``` blurred vision urinary retention dry mouth dry eyes constipation orthostatic hypotension photosensitivity ```
56
extrapyramidal effects
akathesia: feeling of restlessness and need for constant movement. Worse in women. Increased risk with increased dosage dystonia: acute muscle rigidity in any muscle of the body; mostly tongue, neck. can occur in first week of treatment laryngospasm, torticollis is a stiff neck with muscle spasms causing lateral contracture, oculogyric crisis eyes roll up in the head, opisthotonos is tightness in entire body with head, back and arched neck pseudoparkinsonism
57
pseudoparkinsonism
``` stooped posture masklike face w minimal affect noted drooling (clozapine) bradykinesia tremors pill-rolling cogwheel rigidity: ratchet-like movement of joints. festinating gait with shuffling, baby steps ```
58
tx of extrapyramidal effects
AIMS to assess treat dystonia with benadryl, report signs of muscle stiffness treat akathesia with antiparkison, beta-blocker, or benzo lowering dose usually helps
59
neuroleptic malignant syndrome
a life-threatening neurologic emergency associated with the use of antipsychotic agents AMS, delirium, rigidity, hyperpyrexia, dysautonomia, elevated CPK, diaphoresis, tachycardia, tachypnea, salivation
60
neuroleptic malignant syndrome tx
d/c drug and switch medication muscle relaxers, antiparkinson drugs 1-2 week recovery time
61
tardive dyskinesia
irreversible neurological syndrome that results in involuntary and repetitive body movements; associated with long-term therapy with conventional antipsychotics more common in females and > 50 y/o
62
tardive dyskinesia tx
change drugs AIMS to assess no cure, but tx to decrease sx
63
agranulotcytosis
medication causes the bone marrow to slow down production of white blood cells highest risk with clozapine lethargy, sore throat, malaise, fever, and mouth ulcers
64
agranulocytosis diagnosis
WBC counts done weekly for six months then every two weeks throughout therapy ≤3500 mm3, the medication is held until it returns to the normal levels of 4000-11000 mm3. ≤1500 mm3, the drug is discontinued forever

do not stop taking the drug abruptly smoking increases the metabolism of some antipsychotics avoid extremes in temperature do not drink alcohol do not take OTCs without physician approval be aware of risks during pregnancy continue to take the med even if feeling well
68
antipsychotic adverse effects: tx
antiparkinson agents increase dopamine to decrease side effects Benztropine (Cogentin) Trihexyphenidyl (Artane) antihistamines have some anticholinergic properties Diphenhydramine (Benadryl) benzodiazepines will relax some rigidity Diazepam (Valium) beta blockers relieve anxiety and tension Propranolol (Inderal) dopaminergic agents will increase dopamine Amantadine (Symmetrel)
69
benztropine (cogentin)
antiparkinson drug restores natural balance of neurotransmitters in CNS caution with antihistamines, tricyclic antidepressants, antacids, antidiarrheals. avoid with tardive dyskinesia, pregnancy, lactation can cause anticholinergic side effects, decreased sweating assess EPS, monitor pulse and BP, administer PO with food.
70
anger interventions
anger becomes negative when it is suppressed, denied or expressed inappropriately NEVER approach an angry client alone remain calm and in control, describe options clearly: express feelings verbally; be truthful, punch the pillow or mattress allow space, de-escalation, maintain eye contact decrease the environmental stimuli offer medication or time out in their room
71
