From the Guidelines
For a patient with persistent agitation despite current treatment, I recommend using a benzodiazepine, such as lorazepam or midazolam, as effective monotherapy for the initial drug treatment of acute agitation, as suggested by the Annals of Emergency Medicine 1. Given the patient's current regimen, which includes Seroquel, olanzapine, Vimpat, Keppra, and scheduled Xanax, it is essential to reassess the treatment strategy to minimize potential polypharmacy issues. The current use of two antipsychotics (Seroquel and olanzapine) may increase side effects without additional benefit. Key considerations for managing agitation in this patient include:
- Evaluating for underlying medical causes of agitation, such as pain, infection, or metabolic disturbances
- Considering non-pharmacological approaches, such as environmental modifications, consistent routines, and behavioral interventions, to reduce agitation without additional medication burden
- Using a benzodiazepine, as recommended by the Annals of Emergency Medicine 1, for rapid sedation, if necessary
- Potentially simplifying the patient's regimen by discontinuing or reducing unnecessary medications, under close monitoring, to minimize side effects and improve tolerability. It is crucial to prioritize the patient's safety and well-being, and a thorough evaluation of the current treatment strategy is necessary to determine the best course of action.
From the Research
Treatment Options for Agitation
The patient's current treatment regimen includes Seroquel, Olanzapine, Vimpat, Keppra, and Xanax, and they were previously on Abilify and venlafaxine. Considering the patient's persistent agitation despite multiple antipsychotics, the following treatment options can be explored:
- Haloperidol, a typical antipsychotic, which can be used alone or in combination with antihistaminergic and anticholinergic drugs such as promethazine, as suggested by 2.
- Benzodiazepines, such as lorazepam, diazepam, and midazolam, which have a more pronounced sedating activity, as mentioned in 2 and 3.
- Atypical antipsychotics, such as aripipiazole, ziprasidone, and olanzapine, which are better tolerated and have a faster onset of action, as discussed in 3.
Combination Therapies
Combination therapies can also be considered, such as:
- The combination of haloperidol and promethazine, which combines the sedative properties of the antihistamine with the more selective calming action of haloperidol, as suggested by 2.
- The use of intramuscular ziprasidone and intramuscular olanzapine, which have shown significant calming effects and are well-tolerated, as mentioned in 3.
- Combinations of antidepressants, mood stabilizers, and atypical antipsychotics, which are common in clinical practice, although the efficacy of most of these combinations has not been studied, as discussed in 4.
Interactions between Medications
When considering combination therapies, it is essential to be aware of potential interactions between medications, such as:
- The interaction between carbamazepine and risperidone, which can decrease the plasma concentrations of both risperidone and its active metabolite, as mentioned in 5.
- The interaction between valproic acid and clozapine, which can either increase or decrease clozapine concentrations, as discussed in 5.
- The interaction between phenobarbital and clozapine, which can decrease clozapine concentrations, as mentioned in 5.
