A patient exhibits agitation, tremors, and hallucinations five days after admission for depression. What is the most appropriate treatment?

• A. Phenobarbital
• B. Diazepam
• C. Phenytoin
• D. Clonidine

Answer: (B)

The most appropriate treatment for a patient exhibiting agitation, tremors, and hallucinations after several days of hospitalization, especially related to depression, is benzodiazepine, such as diazepam. In this scenario, the presentation suggests possible withdrawal from substances or acute delirium, conditions where benzodiazepines are typically indicated for management of agitation and tremors.

Benzodiazepines work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA), helping to calm the nervous system. This is particularly beneficial in patients who may be experiencing withdrawal symptoms from alcohol or other depressants, which can manifest as agitation, tremors, and hallucinations.

Other options like phenobarbital may also have sedative properties but are usually considered in seizure management or specific withdrawal scenarios, making them less preferable for immediate sedation and managing acute psychomotor agitation. Phenytoin is primarily used for seizure control and would not address the agitation and hallucinations directly. Clonidine has uses in managing anxiety and withdrawal symptoms from opioids but is less effective for acute agitation and does not have sedative effects like benzodiazepines.

Thus, diazepam stands out as the most effective and appropriate choice for this
