Pharmacokinetics in children

The average clearance and the steady state volume of distribution of remifentanil are high in younger children and decrease with increasing age to the values for healthy young adults in 17-year-olds. Linear maturation of remifentanil clearance may be explained by the fact that remifentanil is metabolized by unspecific tissue and plasma esterases. Maturation of their metabolic capacity, however, has not yet been studied. (Ziesenitz 2018).

The elimination half-life of remifentanil in neonates and infants (< 1 year) is comparable to  adults after correctection for lower bodyweight. Changes in the analgesic effect quickly follow changes in the infusion rate of remifentanil and are similar to those observed in healthy young adults (SmPC Ultiva). 

Pharmacokinetics of remifentanil in anesthetized pediatric patients undergoing elective surgery or diagnostic procedures:

Age Dose Vd  CL Half Life Source
<2 months 5 microg/kg over 1 min 0,452 L/kg     3,4-5,7 min   Ross 2001, n=42 (0-18 years)
>2 months 5 microg/kg over 1 min 0,22-0,38 L/kg  
2m – 2 y 5 microg/kg over 1 min 90-92 mL/min/kg
>2 years 5 microg/kg over 1 min 46-76  mL/min/kg
0.74 (0.3–1.0) years (n=7)     16.23 L/70 kg   Standing 2010  Pop-PK Estimates

The PK during postoperative sedation was described by a 2-compartment allometric model during postoperative sedation (Rigby Jones 2007)

Warnings & precautions in children

The rapid administration of remifentanil provides insufficient sedation and is associated with a high risk of chest wall rigidity in preterm neonates (De Kort 2017). This can be managed by slow and continuous infusion and by using the minimum effective dose. (Maroni 2023)
