Insugen 30/70 100IU Refil Cartridge is a premixed insulin formulation containing 70% insulin isophane (NPH insulin) and 30% human insulin, designed for the management of diabetes mellitus requiring insulin therapy. This biphasic insulin preparation combines intermediate-acting insulin isophane with short-acting human insulin, providing both basal and prandial glycemic control. The intermediate-acting component ensures prolonged insulin activity to maintain baseline glucose levels, while the short-acting fraction facilitates rapid postprandial glucose reduction. Insugen 30/70 is indicated for patients with type 1 diabetes mellitus and insulin-dependent type 2 diabetes mellitus who require a consistent and reliable insulin regimen. The 100IU refill cartridge is compatible with specified insulin delivery devices, allowing precise dosing and ease of administration. Proper storage conditions must be maintained to preserve insulin potency. Dosage should be individualized based on patient’s glycemic response, lifestyle, and concurrent medical conditions, with regular monitoring of blood glucose levels to minimize the risk of hypoglycemia or hyperglycemia. Healthcare professionals should provide comprehensive patient education regarding injection techniques, dose adjustments, and recognition of adverse effects. Insugen 30/70 offers an effective option for optimizing glycemic control in insulin-dependent diabetic patients.
