Pharmacokinetics in children

The kinetics of glycopyrronium in children aged > 2 months do not depend on the age. There is high inter-individual variability [Rautakorpi 1994, Rautakorpi 1998]

      • Initial dose: Glycopyrronium: 38.4 microg./kg/day in 3 doses. Max single dose: 1.9 mg/dose.
      • Maintenance dose: increase every 5-7 days depending on the effect and tolerance with dose increments of 38,4 microg./kg/day to 76.8 - 192 microg./kg/day in 3 doses. Max: 5.7 mg/day. Max single dose: 1.9 mg/dose.

      • Doses of up to 656 microg./kg/day (glycopyrronium) have been described in individual cases.
As anticholinergic treatment: pre-operative, intra-operative

      • Glycopyrroniumbromide: 4 - 5 microg./kg/dose, as required repeat intra-operatively as an intravenous administration. Max single dose: 400 microg./dose.
Excess salivation: treatment with RYBRILA
  • Oral
    • 2 months up to 18 years
      • Initial dose: Glycopyrronium: 48 microg./kg/day in 3 doses. Max single dose: 2.4 mg/dose.
      • Maintenance dose: increase every 5-7 days depending on the effect and tolerance with dose increments of 48 microg./kg/day to 96 - 240 microg./kg/day in 3 doses. Max: 7.2 mg/day. Max single dose: 2.4 mg/dose.

      •  

         
CAUTION:
  • Oral
    • 0 years up to 18 years

      • The products Sialanar and Rybrila are NOT interchangeable due to a difference in bioavailability. The bioavailability of Sialanar is 20% higher than that of Rybrila. This has implications for dosing recommendations .

        Both products have different concentrations and thus the volume to be administered per dose is different. This may be relevant in children with swallowing difficulties. 

Renal impaiment in children > 3 months

If the GFR is < 30 ml/min/1.73m², the risk of anticholinergic side effects is increased. Lowering the dose may be necessary.

Side effects in children

Oral administration:

Very common (≥ 10%): irritability. Excessive flushing. Nasal congestion, decreased bronchial secretion. Dry mouth, vomiting, diarrhea, constipation. Urinary retention.

Common (1-10%): upper respiratory tract infection, pneumonia. urinary tract infection. Agitation, feeling drowsy. Nosebleed. Skin rash. Fever.

Uncommon (0.1-1%): headache, nystagmus. Mydriasis. Halitosis, esophageal candidiasis, disturbed gastrointestinal motility, pseudo-obstruction. Dehydration, thirst.

Further reported: restlessness, overactive behavior, concentration disorder, shyness, anxiety, feeling sad, crying, frustration, tantrum, mood changes, insomnia. Closed-chamber glaucoma, photophobia, dry eyes. Temporary bradycardia. Sinusitis. Nausea. Dry skin, decreased perspiration. Micturition urge. Hypersensitivity reaction, angioedema. Decrease in neutrophils, erythrocytes, monocytes, creatinine, carbon dioxide, bicarbonate.



Following intravenous or intramuscular administration:
Malignant hyperthermia and especially in children: cardiac arrhythmias (including bradycardia, ventricular tachycardia and ventricular fibrillation), cardiac arrest, hypertension, hypotension, convulsions and respiratory arrest have been reported.

Boriosi et al. 2022 describes a higher prevalence of airway obstruction, emergency airway intervention and laryngospasm when an anticholinergic (glycopyrronium or atropine) is used compared to no anticholinergic in paediatric procedural sedation.

Contra-indications

No information available on specific contra indications in children.

Warnings & precautions in children

Children under the age of 1 year and children with Down's syndrome, spastic paralysis or brain damage can be particularly sensitive to anticholinergic effects. Monitor carefully in patients with kidney damage due to the prolonged clearance. Paradoxical excitation can occur in young children.
The injection contains benzyl alcohol.
