Objective: To evaluate the effectiveness of tramadol hydrochloride for the treatment of chronic pain refractory to previous treatment in two pediatric patients.
Methods: Tramadol hydrochloride was administered (50 mg/day to 150 mg/day) to two siblings with Ehlers-Danlos syndrome - Hypermobility type refractory to previous pharmacological treatments, and changes in pain intensity and physical activity were assessed.
Results: Pain intensity decreased and physical activity improved within days of starting therapy. Positive results have been maintained for 30 months.
Conclusions: Tramadol hydrochloride was a safe and effective treatment for relieving chronic pain in two pediatric patients suffering from the hypermobility type of Ehlers-Danlos syndrome. No morbidity or side effects were noted during the 30-month follow-up.
