Insights
Oral ketamine shows promise for pediatric chronic pain management. Dosages up to 1 mg/kg were found safe for 14-day use in children, with some experiencing significant pain relief.
Area of Science:
- Pediatric Pain Management
- Pharmacology
Background:
- Chronic pain affects a significant number of children.
- Current pain management strategies for children have limitations.
- Oral ketamine is being explored as an alternative analgesic.
Purpose of the Study:
- To determine the safety of higher oral ketamine dosages for pediatric sedation.
- To evaluate oral ketamine as a treatment option for chronic pain in children.
Main Methods:
- A prospective study involving 12 children with chronic pain.
- Administered oral ketamine for 14 days at doses from 0.25-1.5 mg/kg/dose, three times daily.
- Assessed toxicity and pain severity at baseline and day 14.
Main Results:
- Two participants at 1.5 mg/kg/dose experienced dose-limiting toxicities (sedation, anorexia).
- Nine participants completed the treatment; five showed pain improvement, including two with complete resolution lasting over four weeks post-treatment.
- One participant discontinued due to new pain.
Conclusions:
- Oral ketamine at 0.25-1 mg/kg/dose appears safe for 14-day administration in pediatric chronic pain patients.
- Further research into optimal dosing and long-term effects is warranted.
Objective:
To assess whether oral ketamine is safe at higher dosages for sedating children and whether it may be an option for the control of chronic pain in children.
Study Design:
A prospective study was performed on 12 children with chronic pain to identify the maximum tolerated dosage of oral ketamine. Participants were given 14 days of oral ketamine, 3 times daily, at dosages ranging from 0.25-1.5 mg/kg/dose. Participants were assessed for toxicity and for pain severity at baseline and on day 14 of treatment.
Results:
Two participants, both treated at 1.5 mg/kg/dose, experienced dose-limiting toxicities (sedation and anorexia). One participant, treated at 1 mg/kg/dose, opted to stop ketamine treatment due to new pain on treatment. Nine participants completed their course of ketamine treatment. Of these 12 children, 5 experienced improvement in their pain scores, 2 with complete resolution of pain, lasting >4 weeks off ketamine treatment.
Conclusion:
Oral ketamine at dosages of 0.25-1 mg/kg/dose appears to be safe when given for 14 days to children with chronic pain.
