Mixtard 30 FlexPen 100 IU/ml Suspension for Injection is a combination insulin product designed to provide both rapid and prolonged blood glucose control. The 30% soluble insulin component acts quickly to reduce blood sugar levels after meals, while the 70% isophane insulin component provides a sustained effect to control blood glucose levels between meals and overnight. The pre-filled pen allows for easy and precise dosing, with each unit delivering 1 IU of insulin. It is important to rotate injection sites to reduce the risk of lipodystrophy and to follow the prescribed dosing schedule.
