Study Notes

Drugs for the Treatment of Central Nervous System Disorders

  • The chapter discusses drugs used to treat central nervous system (CNS) disorders, specifically psychiatric disorders.
  • Three categories of functional disorders are discussed.
  • Basic precautions for dental professionals when treating patients with psychiatric disorders are outlined.
  • Antipsychotic agents, their mechanisms of action, adverse reactions, drug interactions, uses, and dental implications are discussed.
  • First-generation antipsychotics and their associated side effects, along with their dental implications, are included.
  • Second-generation antipsychotics and their side effects, drug interactions, uses, and dental implications are also discussed.
  • Antidepressant agents, including mechanism of action, side effects, and drug interactions are detailed.
  • Several other antidepressant types and their potential implications are listed.
  • Several drugs used for bipolar disorder are listed.
  • Psychiatric disorders, including schizophrenia, affective disorders, and neuroses are discussed.
  • Characteristics of each of these disorders are outlined (e.g. schizophrenia; positive symptoms, negative effects).
  • Communication and compliance issues with psychiatric patients are addressed.
  • Specific drugs are listed and described for functional psychiatric disorders (e.g.: first generation antipsychotics and second-generation antipsychotics).
  • Adverse drug reactions and dental implications are noted for many classes of drugs.
  • Lists of specific drugs within the categories are included.
  • Included is information about the mechanisms of action of various types of psychiatric drugs.

Antipsychotic Agents

  • First-generation antipsychotics include: Fluphenazine, Haloperidol, Loxapine, Perphenazine, Thiothixene, and Chlorpromazine.
  • Second-generation antipsychotics include: Aripiprazole, Asenapine, Clozapine, Iloperidone, Lurasidone, Olanzapine, Paliperidone, Risperidone, Ziprasidone.
  • First-generation agents are primarily dopamine antagonists.
  • Second-generation agents act on more than one receptor.

Antipsychotic Agents: Mechanism of Action

  • First-generation agents primarily target dopamine receptors.
  • Second-generation agents target multiple receptors.
  • Agents produce slowing of psychomotor activity, calming of emotional responses, and suppression of hallucinations and delusions.
  • Some agents have antiemetic properties.

First-Generation Antipsychotic Agents: Adverse Reactions

  • Sedation is a common side effect.
  • Extrapyramidal effects (including acute dystonia, parkinsonism, akathisia, and tardive dyskinesia) are possible side effects.
  • Orthostatic hypotension, tachycardia, and seizures are also potential side effects.
  • Anticholinergic effects may occur as well.

Second-Generation Antipsychotic Agents: Adverse Reactions

  • Weight gain is associated with some agents (e.g. clozapine, olanzapine, quetiapine).
  • Agranulocytosis and granulocytopenia are possible side effects of clozapine.
  • Hyperglycemia and diabetes are also potential adverse reactions
  • Some agents may increase the risk of tachycardia (e.g., ziprasidone).
  • Metabolic syndrome is a potential side effect associated with some agents.

Antipsychotic Agents: Drug Interactions

  • Antipsychotics can interact with central nervous system (CNS) depressants, potentially increasing sedation and causing respiratory depression.
  • Epinephrine can interact with antipsychotics, potentially causing hypotension.
  • Antipsychotics can interact with anticholinergic agents by exhibiting additive anticholinergic effects.

Antipsychotic Agents: Uses

  • Antipsychotics are commonly used to treat schizophrenia.
  • They can also be used for their antiemetic effects (e.g., Prochlorperazine).
  • Some are used for bipolar disorder.
  • Others may be used to treat depression, intractable hiccups, or certain drug withdrawals.

Antipsychotic Agents: Dental Implications

  • Use caution with patient interactions; some antipsychotics may cause xerostomia, and extrapyramidal effects which can affect TMJ.
  • Oral hygiene instructions are necessary due to xerostomia and other potential effects.
  • Epinephrine can safely be used; orthostatic hypotension is a possible side effect.

Antidepressant Agents

  • Electroconvulsive therapy (ECT), Selective serotonin reuptake inhibitors (SSRIs), Serotonin norepinephrine reuptake inhibitors (SNRIs), Tricyclic antidepressants (TCAs), and other antidepressant agents.

Selective Serotonin Reuptake Inhibitors (SSRIs)

  • Inhibit the reuptake of 5-hydroxytryptamine (5-HT).
  • May cause xerostomia, altered taste, aphthous stomatitis, glossitis, increased salivation, enlarged salivary glands, and tongue discoloration or edema.

Selective Serotonin Reuptake Inhibitors (SSRIs) (specific drugs)

  • Citalopram (Celexa)
  • Duloxetine (Cymbalta)
  • Escitalopram (Lexapro)
  • Fluoxetine (Prozac)
  • Fluvoxamine (Luvox)
  • Sertraline (Zoloft)
  • Paroxetine (Paxil)

Serotonin Norepinephrine Reuptake Inhibitors (SNRIs)

  • Inhibit the reuptake of both serotonin and norepinephrine.
  • Common side effects may include: sweating, tachycardia, urinary retention.

Tricyclic Antidepressants (TCAs)

  • Potential side effects include: cardiac toxicity, effects similar to amphetamines and epinephrine, interactions with monoamine oxidase inhibitors (MAOIs) leading to severe toxic reactions.
  • Additive anticholinergic effects are a concern.

Monoamine Oxidase Inhibitors (MAOIs)

  • Inhibit monoamine oxidase.
  • Potential side effects include sleep disturbances, orthostatic hypotension, sexual dysfunction, and weight gain.
  • Drug interactions result in overdose toxicities; specific prohibitions from diet and other medications are a concern.

Other Antidepressants: Bupropion (Wellbutrin [SR])

  • Potential side effects may include: seizures, constipation, nausea, vomiting, xerostomia, headache, excessive sweating, tremors, agitation, and dizziness.

Trazodone (Desyrel)

  • Advantages: Fewer anticholinergic effects, less cardiotoxic.
  • Disadvantages: Sedative, associated with priapism.

Nefazodone, Mirtazapine, Vilazodone, and Vortioxetine

  • Nefazodone (Serzone): 5-HT modulator; possibly causes xerostomia, increased serum levels of other medications, and hepatic failure.
  • Mirtazapine (Remeron): 5-HT modulator; potential effects are somnolence, weight gain, and constipation.
  • Vilazodone (Viibryd): Serotonin reuptake inhibitor.
  • Vortioxetine (Trintellix)

Suicide and Antidepressants

  • All antidepressants carry a black box warning regarding suicidal thoughts and behaviors.

Dental Implications

  • Sympathomimetic amines and second-generation antipsychotics may cause xerostomia.

Drugs for Treatment of Bipolar Depression: Lithium

  • Potential side effects, including polyuria, fine hand tremor, thirst, slurred speech, ataxia, nausea, vomiting and diarrhea.
  • Overdose toxicity may cause CNS symptoms, muscle rigidity, hyperactive deep reflexes, excessive tremors, and muscle fasciculation.

Antiepileptic Drugs

  • Carbamazepine, Valproate, Gabapentin.
  • Atypical antipsychotics (Olanzapine, Aripiprazole) may also be used as antiepileptic agents.
