General Principles of Pharmacotherapy - Meds Mood Menders?
- Symptom-targeted, not curative; often off-label.
- Adjunct to psychotherapy (primary treatment).
- No FDA-approved drugs for PDs directly.
- Set realistic expectations; watch polypharmacy risks.
- Target symptom domains:
- Cognitive-perceptual.
- Affective dysregulation.
- Impulsivity-aggression.
⭐ Pharmacotherapy for personality disorders is symptom-targeted and often off-label, as no drugs are FDA-approved for PDs themselves; it serves as an adjunct to psychotherapy.
Cluster A Pharmacotherapy - Oddity Antidotes
📌 Cluster A = Awkward/Aloof, Antipsychotics Aid.
| PD | Key Symptoms Targeted | Drug Class(es) | Examples | Key Dosing Considerations |
|---|---|---|---|---|
| Paranoid | Suspiciousness, paranoia | Low-dose AP | Risperidone, Olanzapine | Low dose |
| Schizoid | Comorbid anxiety/dep | SSRIs | Fluoxetine | For comorbidity |
| Schizotypal | Psychotic-like sx; anxiety/dep | Low-dose AP; SSRIs | Risperidone; Sertraline | Low-dose AP; SSRIs for sx |
Borderline PD Pharmacotherapy - Storm Stabilizers
Target symptom domains for BPD pharmacotherapy. No FDA-approved drugs; off-label use common. 📌 BPD meds: SAMS - SSRIs, Antipsychotics, Mood Stabilizers.
- Affective Dysregulation (mood swings, anger):
- Mood Stabilizers: Lamotrigine (titrate slowly), Valproate, Topiramate.
- SSRIs: Fluoxetine.
- Atypical Antipsychotics: Olanzapine, Aripiprazole, Quetiapine.
- Impulsivity/Aggression:
- Mood Stabilizers: Lithium, Valproate.
- Antipsychotics.
- SSRIs (for impulsivity).
- Naltrexone (self-harm).
- Cognitive-Perceptual Symptoms (transient paranoia, dissociation):
- Low-dose Antipsychotics: Risperidone, Olanzapine.
- Anxiety:
- SSRIs.
- Anxiolytics (short-term, cautious benzodiazepines).
⭐ Lamotrigine is a mood stabilizer often used in Borderline PD for affective instability and impulsivity, requiring slow titration to minimize risk of Stevens-Johnson syndrome.
Other Cluster B Pharmacotherapy - Impulse Controllers
| PD | Target Symptoms | Pharmacotherapy | Notes |
|---|---|---|---|
| ASPD | Aggression/Impulsivity | See blockquote; SSRIs (anxiety) | Core traits resist |
| HPD | Comorbid depression/anxiety | Antidepressants (SSRIs) | Limited; for comorbidity |
| NPD | Mood lability/Rejection sens. | Antidepressants (SSRIs) | Limited; for mood symptoms |
| Mood swings | Lithium | For mood swings |
Cluster C Pharmacotherapy - Anxiety Easers
📌 Cluster C = Concerned/Clingy/Compulsive, SSRIs often Soothe.
| PD | Symptoms | Drug Class | Examples | Considerations |
|---|---|---|---|---|
| APD | Social anxiety | SSRIs/SNRIs | Venlafaxine | Pervasive social anxiety |
| Performance anxiety | Beta-blockers | Propranolol | Situational performance anxiety | |
| DPD | Anxiety/depression | Antidepressants | SSRIs (e.g., Escitalopram) | Comorbid conditions |
| Acute anxiety | Benzodiazepines | Lorazepam | ⚠️ Cautious, short-term (dependence risk) | |
| OCPD | Obsessionality, rigidity | SSRIs, Clomipramine | Fluoxetine, Sertraline, Clomipramine | Higher doses for rigidity; augmentation possible |
High‑Yield Points - ⚡ Biggest Takeaways
- SSRIs: Often first-line for emotional dysregulation, anxiety, and impulsivity (especially BPD).
- Antipsychotics (low-dose): Target cognitive-perceptual symptoms, anger, and severe impulsivity.
- Mood Stabilizers: Manage affective lability and impulsive aggression (e.g., valproate, lamotrigine).
- Benzodiazepines: Generally avoided due to risks of disinhibition, dependence, and paradoxical agitation.
- Adjunctive Therapy: Pharmacotherapy is adjunctive to psychotherapy, targeting specific symptom domains, not curative.
- Symptom-Focused: No FDA-approved drugs for PDs; treatment is empirical, targeting distressing symptoms.
