Patients with renal or hepatic impairment: Studies in patients with hepatic impairment were not performed given the metabolic fate of glucosamine as an endogenous substance. Therefore, no dose adjustment is considered necessary in patients with renal or hepatic impairment.
Children and teenagers: The pharmacokinetics of glucosamine have not been studied in children and adolescents.
Elderly patients: No specific pharmacokinetic studies have been performed for elderly patients; however, clinical safety and efficacy studies included mainly elderly patients. No dose adjustment is required.
