“NUR 256 (Medication Management) Week 7 reviews benzodiazepines, highlighting why they are preferred over barbiturates. These flashcards emphasize their safety profile, therapeutic advantages, and clinical relevance in medication management.”

Print Embed Import Report

Benzodiazepines have become among the most widely prescribed drugs, why are they preferred over older hypnotic agents such as barbiturates?

Specific dose related anxiolytic(aniti anixety) action
Lower fatality rates following acute toxicty/overdose
Lower potential for abuse
More favourable adverse effect profiles
The availability of a specific antidote(Flumazenil)
Fewer potentially serious drug interactions when administered with other medications.

Akathisia -	Description- Motor restlessness, unable to sit/stand still person feels urgent need to move/pace/rock/tap foot. Can also present with apprehension, irritability and general uneasiness. Treatment- Reducing dose of neuroleptic agent, switching to an atypical psychotic agent eg Benztropine, Diazapam
Dystonia -	Description- Muscle spasms of face/tongue/neck/jaw or hands, hyperextension of neck/trunk arching of back and oculogyric(fixed upward gaze) crisis may occur. Acute reactions require immediate intervention! Treatment- Reducing dose and depending on the severity of reaction adminisration of Benztropine IM or IV

Tardive Dyskinesia -	Description- Oral or facial dyskinesia(involuntary muscle movements such as tongue darting, lip smacking etc) Reducing or stopping neuroleptic agent ASAP No effective treatment so prevention is vital as it can be irreversible.
Neuroleptic Malignant Syndrome -	Rare but potentially fatal adverse effect for a person on typical antipsychotics symptoms include high temperature, muscle rigidity, altered consciousness and impaired automnomic homeostasis. Treatment includes widthdrawal of the drug, hydration and possible administration of Bromocriptine(dopamine agonist) & Dantrolene to control muscle spasms.
