Xglar One 100IU Prefilled Syringe contains Insulin Glargine (100IU), a long-acting basal insulin analog used for the management of diabetes mellitus. It provides a steady and prolonged insulin release, mimicking the body’s natural basal insulin secretion, thereby helping to maintain stable blood glucose levels over a 24-hour period with minimal peaks. Xglar One is indicated for the treatment of type 1 and type 2 diabetes in adults and pediatric patients requiring basal insulin to achieve glycemic control. The prefilled syringe formulation allows for accurate dosing and ease of administration, enhancing patient compliance. Insulin Glargine exerts its effect by facilitating cellular glucose uptake and inhibiting hepatic glucose production, contributing to overall glycemic regulation. It should be administered subcutaneously once daily, preferably at the same time each day, with dose adjustments based on individual glycemic response and clinical judgment. Patients should be monitored regularly for signs of hypoglycemia, the most common adverse effect, and educated on appropriate management. Xglar One should be used as part of a comprehensive diabetes management plan, including diet and exercise. Caution is advised in patients with renal or hepatic impairment, and it is contraindicated in patients with hypersensitivity to insulin glargine or any excipients.
