Insulins and analogues are a type of therapeutic group used to treat diabetes by replacing or supplementing the body's insulin. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels in the body. Insulin and analogues work by mimicking the action of natural insulin, helping to control blood sugar levels and preventing complications associated with diabetes. There are several types of insulin and analogues, including rapid-acting, long-acting, and combination insulins, each with different onset and duration of action. The choice of insulin or analogue depends on the individual's needs and treatment goals. Insulins and analogues are typically administered through injection or insulin pump and require careful monitoring and dosage adjustments to ensure optimal blood sugar control.
