Study Notes
Benzodiazepines Overview
- Common benzodiazepines include alprazolam, lorazepam, chlordiazepoxide, oxazepam, clorazepate, prazepam, diazepam, and clonazepam.
- Benzodiazepines are primarily used for managing anxiety symptoms.
- Other options for anxiety treatment include SSRIs as first-line, buspirone and TCAs as second-line, and propranolol for acute symptom relief before events.
Antipsychotics
-
First-Generation Antipsychotics (Typical):
- Include Haloperidol and chlorpromazine.
- Associated with extrapyramidal side effects (EPS) and exacerbation of negative symptoms.
- Chlorpromazine can cause pigmentary deposits in the retina and cornea.
-
Second-Generation Antipsychotics (Atypical):
- Examples: Clozapine, Aripiprazole, Olanzapine, and Quetiapine.
- More effective for positive symptoms of schizophrenia but may induce metabolic side effects, leading to conditions like diabetes mellitus.
- Clozapine can cause agranulocytosis, necessitating monitoring of absolute neutrophil counts (ANC) and white blood cells (WBC).
Special Considerations in Treatment
- Antipsychotics used for Parkinson's disease include Quetiapine and Pimavanserin.
- Tardive Dyskinesia (TD) can be treated with Valbenazine, the first FDA-approved medication for this condition.
- Medications for extrapyramidal effects include Benztropine, Diphenhydramine, and benzodiazepines.
Drug Metabolism and Interaction
- Smoking can increase the metabolism of Clozapine and Olanzapine, requiring higher doses to maintain therapeutic effects as smoking affects drug concentration and clearance.
- Patients taking Olanzapine with high glucose levels may need to be switched to Haloperidol, a first-generation antipsychotic with fewer metabolic changes.
Summary of Treatment Efficacy
- Second-generation antipsychotics are most effective in treating positive symptoms in schizophrenia.
- Negative symptoms are worsened and EPS may develop with first-generation antipsychotic use.
