Dexmedetomidine

Generic Medicine
Indications

Dexmedetomidine is a relatively selective alpha-2 adrenergic receptor agonist indicated for:

  • Sedation of initially intubated and mechanically ventilated patients in intensive care settings. Dexmedetomidine should be administered by continuous infusion for not more than 24 hours.
  • Sedation of non-intubated patients before and/or during surgical and other medical procedures.
Pharmacology

Dexmedetomidine is a selective alpha-2 adrenoceptor agonist. By binding to presynaptic alpha-2 receptors, it inhibits the release of norepinephrine, thereby reducing the transmission of pain signals. Activation of postsynaptic alpha-2 receptors decreases sympathetic nervous system activity, leading to reduced blood pressure and heart rate.

Dosage Administration

Individualize and titrate Dexmeditomidine dosing to desired clinical effect.

Administer Dexmeditomidine using a controlled infusion device.

Dilute the 200 mcg/2 mL (100 mcg/mL) vial contents in 0.9% sodium chloride solution to achieve required concentration (4 mcg/mL) prior to administration.

The 200 mcg/50 mL single-use bottles do not require further dilution prior to administration.

For Adult Intensive Care Unit Sedation: Generally initiate at one mcg/kg over 10 minutes, followed by a maintenance infusion of 0.2 to 0.7 mcg/kg/hour.

For Adult Procedural Sedation: Generally initiate at one mcg/kg over 10 minutes, followed by a maintenance infusion initiated at 0.6 mcg/kg/hour and titrated to achieve desired clinical effect with doses ranging from 0.2 to 1 mcg/kg/hour.

Alternative Doses: Recommended for patients over 65 years of age and awake fiberoptic intubation patients.
