Mechanism of Action

Precedex is a relatively selective alpha2-adrenergic agonist with sedative properties. Alpha2 selectivity is observed in animals following slow intravenous infusion of low and medium doses. Both alpha1 and alpha2 activity is observed following slow intravenous infusion of high doses or with rapid intravenous administration.

Precedex In Sodium Chloride Indications

Indications

For sedation of initially intubated and mechanically ventilated adult patients during treatment in an intensive care setting. For sedation of non-intubated adult patients prior to and/or during surgical and other procedures. For sedation of non-intubated pediatric patients aged 1 month to <18 years prior to and during non-invasive procedures.

Precedex In Sodium Chloride Dosage and Administration

Adult

Individualize. Give by continuous infusion not to exceed 24hrs. Initiation of ICU sedation: loading infusion of 1mcg/kg over 10mins; patients converting from alternate sedative therapy: a loading dose may not be required; >65yrs, hepatic impairment: reduce dose. Maintenance of ICU sedation: 0.2–0.7mcg/kg/hr; >65yrs, hepatic impairment: reduce dose. Initiation of procedural sedation: loading infusion of 1mcg/kg over 10mins, less invasive procedures: 0.5mcg/kg over 10mins; awake fiberoptic intubation patients: loading infusion of 1mcg/kg over 10mins; >65yrs: loading infusion of 0.5mcg/kg over 10mins; hepatic impairment: reduce dose. Maintenance of procedural sedation: initially 0.6mcg/kg/hr and titrated to achieve desired effect with doses ranging from 0.2–1mcg/kg/hr; awake fiberoptic intubation patients: 0.7mcg/kg/hr until endotracheal tube is secured; >65yrs, hepatic impairment: reduce dose.

Children

Initiation of ICU or other surgical procedural sedation: not established. Initiation of sedation during non-invasive procedures: <1month: not established. Individualize. Give by continuous infusion not to exceed 24hrs. 1month–<2yrs: loading infusion of 1.5mcg/kg over 10mins; 2yrs–<18yrs: loading infusion of 2mcg/kg over 10mins; consider dose reduction if clinically indicated. Maintenance of sedation during non-invasive procedures (1month–<18yrs): initially 1.5mcg/kg/hr and titrated to achieve desired effect with doses ranging from 0.5–1.5mcg/kg/hr; titrate as clinically warranted based on response.
