Mixtard 30 100 IU/ml Suspension for Injection is a combination insulin product that contains 30% soluble insulin and 70% isophane insulin. This formulation provides both immediate and extended blood glucose control, making it suitable for individuals with type 1 and type 2 diabetes mellitus. The insulin is administered subcutaneously, typically 20–30 minutes before meals, to facilitate glucose uptake by muscle and fat cells and to inhibit glucose production by the liver. The dosage and administration schedule should be individualized based on the patient's needs, blood glucose levels, and doctor's recommendations. Common side effects may include hypoglycemia, injection site reactions, and weight gain. Patients should consult their healthcare provider for personalized dosing and administration instructions.
