Glycopyrronium Bromide should be prescribed by physicians experienced in the treatment of paediatric patients with neurological disorders.
Posology
Due to the lack of long-term safety data, Glycopyrronium bromide oral solution is recommended for short-term intermittent use (see section 4.4 and 5.1)
The dosage must be measured and administered with the graduated syringe included in the pack.
The dosing schedule for Glycopyrronium bromide oral solution is based on the weight of the child with the initial dosing of 0.02 mg/kg to be given orally three times daily and titrate in increments of 0.02 mg/kg every 5-7 days based on therapeutic response and adverse reactions. The maximum recommended dosage is 0.1 mg/kg three times daily not to exceed 1.5-3 mg per dose based upon weight. For greater detail, see Table 1.
During the four-week titration period, dosing can be increased with the recommended dose titration schedule while ensuring that the anticholinergic adverse events are tolerable. Prior to each increase in dose, review the tolerability of the current dose level with the patient's caregiver.
Younger children may be more susceptible to adverse events and this should be kept in mind when dose adjustments are carried out.
Following the dose titration period, the child's sialorrhoea should be monitored, in conjunction with the carer at no longer than 3 monthly intervals, to assess changes in efficacy and/or tolerability over time, and the dose adjusted accordingly.

Paediatric population – children aged < 3 years
Glycopyrronium Bromide oral solution is not recommended for use in children younger than 3 years.
Adult population
Glycopyrronium Bromide is indicated for the paediatric population only. There is limited clinical trial evidence on the use of glycopyrronium in the adult population with pathological drooling.
Elderly population
Glycopyrronium Bromide is indicated for the paediatric population only. The elderly have a longer elimination half-life and reduced medicinal product clearance as well as limited data to support efficacy in short-term use. As such Glycopyrronium Bromide should not be used in patients over the age of 65 years.
Hepatic Impairment
Clinical studies have not been conducted in patients with hepatic impairment. Glycopyrrolate is cleared predominantly from the systemic circulation by renal excretion and hepatic impairment is not thought to result in a clinically relevant increase in systemic exposure of glycopyrronium.
Renal impairment
Elimination of glycopyrrolate is severely impaired in patients with renal failure. Glycopyrronium is contraindicated in those with severe renal failure (see section 4.3). For patients with Mild to moderate renal impairment (eGFR <90 - ≥30 ml/min/1.73m2) doses should be reduced by 30%.
Other licensed glycopyrronium products are not all interchangeable on a milligram-for-milligram basis due to differences in bioavailability; please refer to the approved posology of the product if changing between products.
Method of administration
For oral use.
Co-administration with food results in a marked decrease in systemic medicinal product exposure. Dosing should be at least one hour before or at least two hours after meals or at consistent times with respect to food intake. High fat food should be avoided. Where the child's specific needs determine that co-administration with food is required, dosing of the medicinal product should be consistently performed during food intake
The dosage syringe provided with the pack is for oral administration only. The correct quantity of Glycopyrronium Bromide oral solution should be measured and administered using the dosage syringe provided.
Instructions for use of the oral syringe:
1. To open the bottle, press the cap down and turn it anti-clockwise (figure 1).
2. Put the syringe adaptor into the bottle neck (figure 2).
3. Take the syringe and put it into the adaptor opening (figure 3).
4. Turn the bottle upside down (figure 4).
5. Fill the syringe with a small amount of solution by pulling the plunger down (figure 4A). Then push the plunger upward in order to remove any possible bubbles (figure 4B). Finally, pull the plunger down to the graduation mark corresponding to the quantity in millilitres (ml) prescribed by your doctor. The top flat edge of the piston should be in line with the graduation mark you are measuring to (Figure 4C).
6. Turn the bottle the right way up (Figure 5A).
7. Remove the syringe from the adaptor (Figure 5B).
8. Put the end of the syringe into your mouth and push the plunger slowly back in to take the medicine (Figure 6).
9. Wash the syringe with water and let it dry before you use it again.
10. Close the bottle with the plastic screw cap - leave the syringe adaptor in the bottle.
Suitable for administration via nasogastric (NG) or percutaneous endoscopic gastrostomy (PEG) tubes. For further instructions see section 6.6.
