Exam 2 Meds Flashcards
Aripiprazole (ABILIFY): what is it
dopamine modulator (less affinity-less EPS), partial agonist, and more affinity for serotonin (reduce affective and cognitive symptoms and help with negative symptoms): particularly with suicide ideation
• Experts believe that Abilify works by adjusting dopamine, instead of completely blocking it, as other atypical antipsychotics do, which affects serotonin
- It raises the level of these brain chemicals when there’s not enough and lowers the level when there’s too much.
- Extended release injectable suspension (Aristada)
Lumateperone-(Caplyta)
60x higher affinity for 5HT2A(this is seratonin) than D2 receptors
• Moderate serotonin reuptake inhibition
• Half-life is 18 hours: long half life
Novel Antipsychotic
Clozapine/Clozaril
• First one and is not first line treatment and 45-50% don’t respond but by adding Lamictal up to 200 mg/day can help
• Helps with– and + SX
• Some studies suggest it is more protective of suicide and used inEurope before USA• Side effect-most serious agranulocytosis
• a marked decrease in granulated WBC’s
• <1% risk
• May acquire an infection
• Deteriorate rapidly
• Bleed spontaneously and ER situation
Novel Antipsychotic
Protocol for Clozapine/Clozaril
• First 6 months blood WBC’s q week
• If stable may proceed to biweekly
• Then monthly after 6 months
• High fiber diet, fluids
• Exercise, Stool softeners/laxatives
• KUB quarterly
Clozapine/Clozaril Side Effects
-Constipation

• Elevated Liver Enzymes: usually mild and transient
Risperdal
• May also alleviate depression and anxiety
• Doses less than6 mg have been linkedwith better outcomes

Novel Antipsychotic
Uzedy (Risperidone)
no loading dose for this one

Novel Antipsychotic
Olanzapine/Zyprexa, Zydis
Used in difficult cases of Schizophrenia,Bipolar, Psychosis
• Weight gain
• Mood relief
• Cognitive improvement
• Metabolic syndrome: they developed DM within 2 weeks of starting ; need to start metformin
Quetiapine/Seroquel
• Atypical antipsychotic
• Less risk of EPS, akathasia and TD
• Not strong antipsychotic agent but has utility as prn medication: for break through symptoms
• Cardiac risks at higher doses
• Annual eye examination due to possible development of cataracts
• Bipolar depression: good for this
• Usually taken at bedtime
Ziprasidone/Geodon
• Atypical antipsychotic not mood stabilizing
• FDA approved for acute Bipolar manic episode
• Comes in oral and IM formulation
• Oral administration-take with food as bioavailability is 80%: take with food to increase bioavailability
• ECG monitoring for QTC prolongation
• Can increase prolactin levels
• Less weight gain
Latuda/Lurasidone HCL
• Black box warning for risk with elderly with dementia: this affects memory ability
• Once a day dosing
• FDA approved for Schizophrenia and Bipolar I Disorder (bipolar depression -BP II)
• Used in adults and childrenage 10-17
• Avoid eating grapefruit or drinking grapefruit juice due to chance of increasing side effects
Invega/Invega Sustenna
• Comes in oral and IM(0.25-1.5ml; monthly)formulations
• Loading dose and one week after: Loading dose every day for one week
• FDA approved for Schizophrenia and Schizoaffective Disorder
• Used in adults and children 12-17 years
• Can be used in clients with advanced liver disease: metabolized by kidneys (will come out in BM as a whole pill)
• Client instruction about elimination of the oral formulation
Lumateperone
• Mechanism of action
– Very high affinity to 5
-HT2A rather than D2 receptors
– Presynaptic agonist and postsynaptic antagonist at D2 receptors
– Moderate serotonin reuptake inhibition
• Pharmacokinetics
– Metabolized by CYP3A4 and UGT
– Effective half-life: 18hr
-Clozapine-Resistant (non-responder)
Pimavanserin (Nuplazid)
-needs to be titrated low dosages, very slowly–> Steven Johnson Syndrome
• Significantly reduced refractory hallucinationsin clozapine
-resistant patients (34 mg./day)
• Add Lamictal up to 200 mg./day can help halfthe patients
• Add Preservative Benzoate (D-amino acidoxidase inhibitor) 1-2 mg./day
• Xanomeline-trospium (combined Kar-XT)
not on the market; it is an agonist, but when combined with another drug, it can also become an antagonist
Antagonists = block receptors; Agonists =binding to receptors
-will be used for Schizophrenia; supposedly has a better AE profile, but it needs to be taken BID
• Xanomeline
- agonist at M1 and M4 receptors
• Dose-dependent for adverse cholinergic side effects (nausea, vomiting, diarrhea, sweating,hypersalivation)
• Trospium
- Muscarinic antagonist
-Added toxanomeline to minimize peripheral effects
• Day 1-2: 50/20 (xanomeline 50 mg/trospium Cl 20 mg) BID, Day 3-7 100/20 BID; Day 7-35100/20 BID or 125/30 BID (based tolerability) 6
