2.2 Dosage Information

Table 1: Dosage Information
  1. INDICATION
  1. DOSAGE AND ADMINISTRATION
  1. Initiation of Intensive Care Unit Sedation
  1. For adult patients: a loading infusion of one mcg/kg over 10 minutes.
  2. For adult patients being converted from alternate sedative therapy: a loading dose may not be required.
  3. For patients over 65 years of age: a dose reduction should be considered [ see Use in Specific Populations (8.5) ].
  4. For adult patients with impaired hepatic-function: a dose reduction should be considered [ see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].
  1. Maintenance of Intensive Care Unit Sedation
  1. For adult patients: a maintenance infusion of 0.2 to 0.7 mcg/kg/ hour. The rate of the maintenance infusion should be adjusted to achieve the desired level of sedation.
  2. For patients over 65 years of age: a dose reduction should be considered [ see Use in Specific Populations (8.5) ] .
  3. For adult patients with impaired hepatic function: a dose reduction should be considered [ see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].
  1. Initiation of Procedural Sedation
  1. For adult patients: a loading infusion of one mcg/kg over 10 minutes. For less invasive procedures such as ophthalmic surgery, a loading infusion of 0.5 mcg/kg given over 10 minutes may be suitable.
  2. For awake fiberoptic intubation in adult patients: a loading infusion of one mcg/kg over 10 minutes.
  3. For patients over 65 years of age: a loading infusion of 0.5 mcg/kg over 10 minutes [ see Use in Specific Populations (8.5) ] .
  4. For adult patients with impaired hepatic function: a dose reduction should be considered [ see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].
  1. Maintenance of Procedural Sedation
  1. For adult patients: the maintenance infusion is generally 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. The rate of the maintenance infusion should be adjusted to achieve the targeted level of sedation.
  2. For awake fiberoptic intubation in adult patients: a maintenance infusion of 0.7 mcg/kg/ hour is recommended until the endotracheal tube is secured.
  3. For patients over 65 years of age: a dose reduction should be considered [ see Use in Specific Populations (8.5) ] .
  4. For adult patients with impaired hepatic function: a dose reduction should be considered [ see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].

2.3 Dosage Adjustment

Due to possible pharmacodynamic interactions, a reduction in dosage of dexmedetomidine injection or other concomitant anesthetics, sedatives, hypnotics or opioids may be required when co-administered [ see Drug Interactions (7.1) ].

Dosage reductions may need to be considered for adult patients with hepatic impairment, and geriatric patients [ see Warnings and Precautions (5.7), Use in Specific Populations(8.6), Clinical Pharmacology (12.3) ].

2.4 Preparation of Solution

Strict aseptic technique must always be maintained during handling of dexmedetomidine injection.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Dexmedetomidine injection, 200 mcg/2 mL (100 mcg/mL)

Dexmedetomidine injection must be diluted with 0.9% sodium chloride injection to achieve required concentration (4 mcg/mL) prior to administration. Preparation of solutions is the same, whether for the loading dose or maintenance infusion.

To prepare the infusion, withdraw 2 mL of dexmedetomidine injection, and add to 48 mL of 0.9% sodium chloride injection to a total of 50 mL. Shake gently to mix well.
