  2. Classes of Psychiatric Medications • Antipsychotics: -first generation -atypical or second generation • Antidepressants: -tricyclics -SSRI’s & SNRI’s -Others (wellbutrin, remeron, nefazodone, trazodone, viibryd) -MAO Inhibitors • Mood Stabilizers: -Lithium -Anticonvulsants

  3. Classes of Psychiatric Medications • Anxiolytics and Hypnotics: -Benzodiazepines -Buspar -Antihistamines (benadryl, vistaril) -Sleep agents (ambien, lunesta, sonata, melatonin) • Stimulants and Cognitive enhancers: -Amphetamines, methylphenidate, strattera, provigil -Aricept, Namenda, Reminyl, Exelon

  4. First Generation Antipsychotics -> D2 Receptors Antagonists * Chlorpromazine=Thorazine * Thioridazine=Mellaril * Fluphenazine=Prolixin (injection) * Perphenazine=Trilafon * Trifluoperazine=Stelazine * Thiothixene=Navane * Haloperidol=Haldol (inj) * Pimozide=Orap

  5. Antipsychotic Side Effects * EPS, TD (haldol) * Sedation * Orthostatic hypotension * NMS *leukopenia(low white blood cell count) * Constipation * Urinary retention, dry mouth, blurry vision * Galactorrhea, breast enlargement * Skin pigmentation (mellaril) * Seizures (increases risk)

  6. ABNORMAL MOVEMENTS • EPS (Extrapyramidal Symptoms): inability to move, akathisia (restlessness), acute dystonia, tremor, difficulty with gait, mouth/tongue tremor. • TardiveDyskinesia: rapid repetitive movements. * Neuroleptic Malignant Syndrome: confusion, fever, muscle rigidity.

  8. SIDE EFFECTS • Sedation (seroquel +++) • Weight gain (zyprexa, clozaril+++) • Metabolic changes (zyprexa, seroquel, clozaril) • EPS, TD • Risks if pregnancy • Constipation, dry mouth • Irritability • Changes in blood cells (clozaril needs blood counts regularly)

  9.

  11. LITHIUM • Thirst/ Increased Urination • Tremor • Weight gain • Nausea, diarrhea • Acne • Fatigue • Thyroid abnormalities • Toxicity: severe tremor, confusion, seizures • Interactions with Diuretics, NSAID’s, lisinopril

  12. Valproic Acid -> Increases GABA transmission • Gastrointestinal • Low platelet count • Tremor • Sedation • Weight gain • Alopecia

  13. Carbamazepine -> Blocks sodium channels • Dizziness, uncoordination • Double vision • G.I. upset • Tremor • Decreased white blood cells • Rash * Interactions with other drugs

  14. Other Mood Stabilizers • Lamotrigine : no weight gain. RASH. • Neurontin: used for pain. Somnolence. • Topiramate : migraine prophylaxis. Weight loss, memory deficits, sedation, osteoporosis. *ALL: Neonatal complications and fetal malformations. Neurological side effects.

  24. Always remember…. • “All things are poison, and nothing is without poison” • Patients with a psychiatric diagnosis have a higher incidence of co-existent medical problems, therefore are at higher risk of pharmacological interactions • Most patients do not take medications as prescribed • Providers forget to ask about the use of CAM • Birth Control • Substance Abuse • Epocrates.com • Erowid.org

  25. Hispanic Population • High risk of depression, anxiety and substance abuse: women • Attempted suicide: high rate in US Latino high school students • Higher rate of mental illness: US born and long-term residents

  26. Challenges of Providing Care to Hispanic Populations • Less than 10% with a Dx seek services • Largest uninsured group in the US • Research on Evidence based treatments tested mainly on white populations • Over-reliance on family and religion • Low socio-economic status: 2-3 times more likely to have a mental illness • Poor Health overall

  27. Factors Interfering with Access to Mental Health Care • Stigma of mental illness and Psychiatry care • Being an “Illegal alien” • Lost in Translation: 1% of APA members are Hispanic • Gender roles • Different Hispanic cultures/ countries • Over-representation in the criminal and Juvenile justice systems
