From the Guidelines

Lorazepam is the most suitable option for an end-stage Parkinson's patient experiencing increased anxiety and combativeness. As a benzodiazepine, lorazepam works quickly to reduce anxiety and agitation by enhancing the effect of GABA, an inhibitory neurotransmitter in the brain. For acute situations, a starting dose of 0.5-1mg orally or sublingually can be effective, with careful titration as needed, as suggested by 1. Lorazepam is preferred over antipsychotics like risperidone (likely what was meant by "perdone") because antipsychotics can worsen Parkinson's symptoms by blocking dopamine receptors. Haloperidol (possibly "hollo doll") is particularly problematic for Parkinson's patients due to its strong dopamine-blocking properties, as noted in 1 and 1. Typing appears to be an error, as it's not a recognized medication. When administering lorazepam, monitor for excessive sedation, respiratory depression, and fall risk. Non-pharmacological approaches should also be implemented, including maintaining a calm environment, following consistent routines, and identifying triggers for anxiety and combativeness. Some key points to consider when using lorazepam include:

  • Starting with a low dose and titrating as needed to minimize side effects
  • Monitoring for signs of excessive sedation, respiratory depression, and fall risk
  • Implementing non-pharmacological approaches to manage anxiety and combativeness
  • Avoiding the use of antipsychotics, especially haloperidol, in Parkinson's patients due to the risk of worsening symptoms. It's also important to note that the use of benzodiazepines like lorazepam should be carefully considered in patients with a history of substance abuse or dependence, as they can be habit-forming, as mentioned in 1. Overall, lorazepam is a suitable option for managing anxiety and combativeness in end-stage Parkinson's patients, but its use should be carefully monitored and adjusted as needed to minimize side effects and maximize benefits.

From the FDA Drug Label

INDICATIONS AND USAGE Lorazepam Oral Concentrate USP is indicated for the management of anxiety disorders or for the short-term relief of the symptoms of anxiety or anxiety associated with depressive symptoms. The best medicine for an end-stage Parkinson’s patient with increased anxiety and combativeness is lorazepam, as it is indicated for the management of anxiety disorders.

  • Lorazepam is a viable option for short-term relief of anxiety symptoms. However, it is essential to note that the effectiveness of lorazepam in long-term use has not been assessed by systematic clinical studies 2. Hollo doll and typing are not relevant to the treatment of anxiety, and perdone is not a recognized medication. Lorazepam is the only suitable option among the given choices for managing anxiety in an end-stage Parkinson’s patient.

From the Research

Treatment Options for End-Stage Parkinson's Patients with Anxiety and Combativeness

  • The provided studies do not directly address the treatment of end-stage Parkinson's patients with increased anxiety and combativeness using the specified medications (Hollo doll, lorazepam, typing, and perdone) 3, 4, 5, 6, 7.
  • However, the studies discuss the treatment of psychosis and anxiety in Parkinson's disease patients using various medications, including quetiapine, clozapine, and pimavanserin 4, 5, 6, 7.
  • Quetiapine has been shown to be effective in controlling visual hallucinations in some patients with Parkinson's disease and psychosis, but its efficacy in treating anxiety and combativeness is not well established 5, 7.
  • Clozapine has demonstrated superiority over placebo in reducing psychotic symptoms in Parkinson's disease patients, but its use may be limited due to potential side effects 4, 6.
  • Lorazepam is a benzodiazepine that may be used to treat anxiety, but its use in end-stage Parkinson's patients with anxiety and combativeness is not supported by the provided studies 3.
  • There is no evidence to support the use of "Hollo doll", "typing", or "perdone" in the treatment of end-stage Parkinson's patients with anxiety and combativeness, as these are not recognized medical treatments 3, 4, 5, 6, 7.
