Glutamune-IV Injection contains L-alanyl-L-glutamine (20 gm) as its active ingredient, a dipeptide composed of alanine and glutamine, designed for intravenous administration. This formulation serves as a vital nutritional supplement, particularly in clinical settings requiring parenteral nutrition support. L-alanyl-L-glutamine is a stable dipeptide that rapidly hydrolyzes to release glutamine and alanine, both essential amino acids involved in numerous metabolic processes. Glutamine plays a crucial role in maintaining nitrogen balance, supporting immune function, and promoting intestinal mucosal integrity, especially in critically ill patients, those undergoing major surgery, or individuals with compromised gastrointestinal function. The stable dipeptide form enhances solubility and reduces the risk of degradation compared to free glutamine, making it suitable for intravenous infusion. Glutamune-IV Injection is indicated for patients with glutamine deficiency or increased metabolic demands where oral supplementation is not feasible. It aids in improving nitrogen balance, reducing catabolism, and supporting recovery by providing a readily utilizable source of glutamine. Administration should be performed under medical supervision with appropriate dosing adjustments based on patient condition and nutritional requirements. Adverse effects are rare but may include hypersensitivity reactions; therefore, monitoring during infusion is recommended.
