Type 2 Diabetes: Treatment for diabetes aims to maintain blood glucose levels as normal as possible and control symptoms to prevent health problems occurring later in life. People with type 2 diabetes are often given medications including insulin to better control their blood glucose levels.
Maximum of these medications are in the form of tablets, but some are given by injection.

All people with diabetes require checking their glucose levels on a regular basis. While taking medication, you may require checking your blood glucose levels more frequently to keep you safe and to secure the medication is becoming the desired effect.
In type 2 diabetes, insulin resistance leads to the condition, injections of insulin are not the first option. Preferably, other drugs are utilized to help boost insulin production. Insulin resistance occurs in the body’s cells don’t respond properly to insulin, that’s responsible for ferrying glucose to cells for energy.
When cells are resistant to insulin, they don’t utilize the insulin efficiently to take the glucose from the bloodstream into the cell. The pancreas requires producing more insulin to succeed this resistance in an effort to normalize blood sugar levels. Researchers continue to look for new and effective drugs.The various commonly prescribed oral medication for type 2 diabetes is metformin.
Classes of medications for type 2 diabetes
- Biguanides
- Sulphonylureas
- Alpha-Glucosidase Inhibitors
- Thiazolidinediones (Glitazones)
- Dipeptidyl Peptidase 4 (DPP4) Inhibitor
- Sodium-Glucose Transporter (SGLT2) Inhibitors
- Incretin Mimetics
- Combination Oral Pills
Biguanides
Chemical name: Metformin, Metformin ER
This group of insulin tablets helps to lower blood glucose levels by reducing the amount of stored glucose released by the liver. They need to be started at a low dose and increased slowly. Metformin is often prescribed for people with type 2 diabetes who are overweight. It generally doesn’t lead to weight gain and may help to manage weight. Metformin may need to be combined with the sulphonylurea or other classes of tablets and/or insulin. Metformin by itself does not cause hypoglycemia but may contribute to hypoglycemia when used in conjunction with a sulphonylurea tablet or insulin.

Insulin therapy
Type 2 diabetes is a progressive condition with decreasing insulin production over time. As they will need insulin treatment to control their blood glucose levels, sometimes with tablets as well. This can happen about 50% of people within 10 years of being diagnosed.
There are many types of insulin, and they each work in a different way. Options include:
- Insulin lispro (Humalog)
- Insulin glulisine (Apidra)
- Insulin aspart (Novolog)
- Insulin detemir (Levemir)
- Insulin glargine (Lantus)
- Insulin isophane (Humulin N, Novolin N)
