Dexmedetomidine is an example of which drug class used in Fear Free premedication?

• A. Alpha-2 agonist.
• B. Benzodiazepine.
• C. Phenothiazine.
• D. Local anesthetic.

Answer: (A)

Dexmedetomidine is an alpha-2 adrenergic agonist. This class provides sedation and analgesia with minimal respiratory depression, making it especially useful in Fear Free premedication where calming the patient and enabling smoother handling without heavy airway compromise is important. Its anxiolytic and analgesic-sparing effects help reduce stress and facilitate a calmer induction, while preserving airway reflexes. Be mindful that it can cause bradycardia and hypotension if dosed too high or used with other depressants, but with careful dosing and monitoring these effects are manageable. In contrast, benzodiazepines are mainly anxiolytics with limited analgesia and potential respiratory effects; phenothiazines sedate and vasodilate but lack analgesia and can lower blood pressure; local anesthetics are for regional numbing rather than systemic sedation.
