The main aim of treatment for diabetes is to reduce your risk of developing complications by keeping your blood glucose (sugar) levels at reasonable levels.
Medicines for type 2 diabetes
There are various medicines that are used to treat type 2 diabetes, such as:
- Sulphonylureas (example, gliclazide, glipizide, glibenclamide)
Metformin works by improving your body's response to the insulin you naturally make. It also reduces the amount of sugar that your liver makes and that your stomach/intestines absorb. Metformin is prescribed in people with type 2 diabetes whose blood glucose levels cannot be lowered with diet, exercise and other lifestyle changes.
Sulphonylureas work by making your pancreas produce more insulin. They are prescribed in people with type 2 diabetes whose blood glucose levels cannot be lowered with metformin. There are several tablets in this group. They include:
- Gliclazide also known as Glizon or Apo-Gliclazide
- Glipizide also known as Minidiab
- Glibenclamide also known as Gliben or Apo-Glibenclamide
This is an insulin sensitiser which helps reduce insulin resistance in your body. Pioglitazone is prescribed in people with type 2 diabetes whose blood glucose levels cannot be lowered with metformin and sulphonylureas.
Acarbose reduces the rise in blood glucose levels after a meal by delaying the breakdown and absorption of carbohydrates in the stomach. Acarbose is prescribed in people with type 2 diabetes whose blood glucose levels cannot be lowered with metformin and sulphonylureas.
Insulin injections are used in type 2 diabetes, when blood glucose levels cannot be lowered with metformin, and sulphonylureas. This is usually when the body no longer produces enough insulin. The manufactured insulin is very similar to our natural human insulin. Insulin is given as an injection, under the skin. It cannot be given as tablets because it is destroyed by chemicals in the stomach. There are various different types of insulin.
