A Brief Overview of Psychotropic Medications Coni Kalinowski, M.D. 8 February 2013 Some general principles regarding medications: • Psychotropic medications are one tool among many that may lessen mental distress. • All medications have “side effects.” No medication is “safe.” • The effects of psychotropic medications on individuals are unique. • Anything can be a side effect of medication. • Side effects of psychotropic medications can mimic psychiatric symptoms. • Psychotropic medications do not cure psychiatric difficulties. • Psychotropic medications do not “treat” behaviors. • The mechanisms of action of psychotropic agents are essentially unknown. Some general principles regarding medications: • “Medical” medications, over-the-counter medications, and herbal remedies can have significant psychotropic side effects. • Medication combinations can be unpredictable. • Recreational substances and “social” substances often interact with psychotropic medications. • Older people, people who have health problems, people who have had brain injuries, and people having intellectual disabilities may be more sensitive to psychotropic medications and their side effects. • Psychiatric treatment must be differentiated from chemical restraint and social control. • No medication is “safe” during pregnancy. • More is not always better. Antipsychotic Medications (Neuroleptics) • Conventional medications (older): • haloperidol (Haldol) • fluphenazine (Prolixin) • pimozide (Orap) • trifluoperazine (Stelazine) • thiothixene (Navane) • perphenazine (Trilafon) • mesoridazine (Serentil) • loxapine (Loxitane) • molindone (Moban) • thioridazine (Mellaril) • chlorpromazine (Thorazine) Antipsychotic Medications (Neuroleptics) Atypical medications (newer): • clozapine (Clozaril) • risperidone (Resperidal) • olanzapine (Zyprexa) • quetiapine (Seroquel) • ziprasodone (Geodon) • aripiprazole (Abilify) • paliperidone (Invega) • iloperidone (Fanapt) • asenapine (Saphris) • lurasidone (Latuda) Antipsychotic Medications (Neuroleptics) Uses: • -reduce hallucinations • -improve organization of thought processes • -reduce preoccupations with improbable beliefs • -tranquilization • -anti-emesis • -treatment of Tourette's disorder Common Side effects of antipsychotics: • • • • • • • • • • • • • • sedation drowsiness anergy decreased motivation slowing of thought processes depression dry mouth or drooling constipation blurred vision weight gain, diabetes, hyperlipidemia orthostatic hypotension amenorrhea galactorrhea gynecomastia Common Side effects of antipsychotics: • • • • • • • • • rashes sun sensitivity sexual dysfunction restlessness restless leg syndrome discontinuation syndrome headache (especially aripiprazole and ziprasidone) nausea and vomiting (especially risperidone and ziprasidone) Neurological side effects of antipsychotics • Parkinsonian Side Effects – – – – – – – – Onset generally about 7 days after beginning antipsychotic medications Key features: "pill-rolling" tremor increased muscle tone and "cogwheeling" stooped, shuffling gait bradykinesia mask facies impaired balance Neurological side effects of antipsychotics • Akathisia – – – – – Characterized by extreme motor restlessness or "nervousness" People may be observed to pace, jog their legs, repeatedly sit then stand When severe, people may not be able to sleep May be a cause of increased SIB or aggression in people having developmental disabilities Onset: immediate to a few days Neurological side effects of antipsychotics • Dystonia – – – – – – – – – Characterized by a sustained, painful contraction of one or more muscle groups. Common presentations: rigid tongue protrusion throat "closing up" or tongue drawn back upward deviation of the eyes torticollis oculogyric crisis Onset: frequently within an hour of dosage, may be recurrent Can be lethal if airway obstruction occurs Neurological side effects of antipsychotics • Tardive Dyskinesia – – – – Characterized by involuntary muscle movements Onset generally after many years of taking antipsychotic medications, but can occur within weeks Can be progressive and permanent Typical movements: • • • • • • • – chewing, lip-smacking, lip-licking, puffing frequent blinking and blepharospasm tongue flickering or protrusion flexion-extension movements of fingers, writhing or arms foot tapping, ankle movements shrugging, twisting of torso or hips eructation, reflux, vomiting Progresses to cause dysphagia, respiratory difficulties, aspiration pneumonia Serious side effects of antipsychotics • • • • • • • • • • neutropenia seizures neuroleptic malignant syndrome cardiac arrhythmias hyperthermia cataracts precipitation of glaucoma priapism diabetes hyperlipidemia Antidepressants • SSRI's – fluoxetine (Prozac) – sertraline (Zoloft) – paroxetine (Paxil) – fluvoxamine (Luvox) – citalopram (Celexa) – escitalopram (Lexapro) Antidepressants • SNRI's and Novel agents – trazodone (Deseryl) – nefazodone (Serzone) – venlafaxine (Effexor) – bupropion (Wellbutrin) – mirtazepine (Remeron) – duloxetine (Cymbalta) – desvenlafaxine (Pristiq) – vilazodone (Viibrid) Antidepressants • Uses: – – – – – – – – – treatment of depression treatment of anxiety treatment of social phobia treatment of panic attacks treatment of eating disorders treatment of attention deficit disorder in adults treatment of migraine treatment in autism (especially SSRI's) treatment of obsessive-compulsive disorder (especially SSRI's) – treatment of irritability in posttraumatic stress disorder Common side effect of antidepressants: • G.I. side effects: nausea, constipation or diarrhea • Sexual and reproductive dysfunction: anorgasmia, erectile dysfunction, decreased libido, dysmenorrhea, menstrual irregularity • Sleep disturbance: insomnia, nightmares, somnolence • Weight gain • headache • tremor • agitation or "jitters" • excessive sweating • palpitations • dry mouth Common side effect of antidepressants: • • • • • • • • • • • • • • weight loss asthenia muscle pain “poop out” dizziness paresthesias visual disturbances, blurred vision akathisia rash sun sensitivity yawning changes in taste discontinuation syndrome worsening of depression Serious side effects of antidepressants • • • • • • • • • seizures intense suicidality or impulsivity kindling of mania or psychosis dyskinesias extrapyramidal side effects electrolyte disturbances elevation of cholesterol decreased platelet aggregation and bleeding birth defects Anticonvulsant Medications • • • • • • Divalproex sodium (Depakote) Carbamazepine (Tegretol) Oxcarbazapine (Trileptal) Topiramate (Topamax) Lamotrigine (Lamictal) Gabapentin (Neurontin) Anticonvulsant Medications • Uses: – – – – treatment of seizure disorders treatment of mood swings treatment of explosive aggression treatment of complex post-traumatic stress disorder Common side effects of anticonvulsants: • • • • • • • • • • • • drowsiness fatigue mental slowing nausea and vomiting tremor rash motor slowing weight gain hair loss (Depakote) changes in blood pressure birth defects suicidal impulses Serious side effects of anticonvulsants • Tegretol • agranulocytosis • aplastic anemia • hyponatremia • hypothyroidism • toxic epidermal necrolysis • Stevens-Johnson syndrome Serious side effects of anticonvulsants • Depakote – • hepatic failure • thrombocytopenia • polycystic ovary • anemia • pancreatitis • hyperammonemia Serious side effects of anticonvulsants • Neurontin – • elevated liver enzymes • hypertension • increased lability • sudden death elevated liver functions • pure red cell apalasia (risk in hemoglobinopathies) Serious side effects of anticonvulsants • Trileptal- hyponatremia • severe cognitive SE • Topamax – severe cognitve SE • kidney stones • hyperthermia, oligohidrosis Common Medication Errors • Over-medication (excessive dosage) – Common causes: – not waiting for therapeutic effect, overshooting the therapeutic dose. – increasing dose in a crisis, but forgetting to return to maintenance dose. – using medication for sedative side effect – “more is better” – failure to compensate for advanced age, medical problems, brain injury Common Medication Errors • Polypharmacy (more than one drug in the same class) – Common causes: – adding a new medication without removing ineffective medications. – stalled cross titration Common Medication Errors • Failure to recognize medication interactions. • Confusion of medication side effect with symptoms of the psychiatric disability. • Failure to assess a change in “medical” health. • Inadequate evaluation of situational and environmental contributors to psychiatric symptoms. Common Medication Errors • Failure to fully assess “medical” medications and non-prescription substances. • Inadequate monitoring of side effects. • Failure to take the person’s report of medication side effects seriously. Common Medication Errors • Over-reliance on medications; inadequate use of alternative or adjunct treatment. • Inadequate attention to informed consent. • Failure to warn about possible prenatal effects of medications.
