Renal Dose Adjustments
No data available; however, the manufacturer recommends routine monitoring of renal function.
Liver Dose Adjustments
No specific dose adjustment guidelines have been suggested; however, glutamine is metabolized to glutamate and ammonia which may increase in patients with hepatic dysfunction. The manufacturer recommends routine monitoring of liver function.
In the event of a patient's transient intolerance to oral intake, a dose may be delayed for up to 2 hours.
Safety and efficacy of glutamine treatment beyond 16 weeks has not been studied.
Generally, dose selection for an elderly patient should be individualized, because of the greater frequency of decreased hepatic, renal, or cardiac function, as well as concomitant disease in this population.
Safety and effectiveness have not been established in pediatric patients (less than 18 years of age).
Data not available
Glutamine has been used in conjunction with recombinant human growth hormone in patients receiving specialized nutritional support.
Glutamine is available in capsule, tablet, powder packet, powder for solution, or powder for suspension form from various manufacturers. Each dose of oral powder should be reconstituted with 8 ounces of water or a volume as determined by the individual manufacturer (volume may be varied according to the patient's preference) prior to consumption.
