Insulin Therapy: The Foundation of Type 1 Diabetes Treatment
Insulin therapy remains the essential and most widely used medication for managing type 1 diabetes. All people with type 1 diabetes require lifelong insulin replacement, typically delivered through injections or insulin pumps, to control blood sugar levels and prevent complications Stokes2024Nabi-Afjadi2024Warshauer2019+2 MORE. While insulin is life-saving, it does not stop the underlying autoimmune process that destroys pancreatic beta cells Ajmal2023Warshauer2019.
Adjunctive and Non-Insulin Medications in Type 1 Diabetes
Use of Non-Insulin Diabetes Medications
Some people with type 1 diabetes are prescribed additional medications to help with blood sugar control or to address other health issues. These include metformin, GLP-1 receptor agonists, SGLT2 inhibitors, DPP-4 inhibitors, and pramlintide. However, the use of these non-insulin diabetes medications is less common and varies by country and patient population Stokes2024Lyons2017Nabi-Afjadi2024+1 MORE. Metformin and GLP-1 receptor agonists are sometimes used to improve insulin sensitivity or reduce insulin requirements Lyons2017Nabi-Afjadi2024Von Scholten2021.
Medications for Comorbidities
Many adults with type 1 diabetes, especially those on Medicare or Medicaid, are prescribed medications for other conditions such as high blood pressure, high cholesterol, and neuropathic pain. Commonly used drugs include atorvastatin (for cholesterol), lisinopril (for blood pressure), and gabapentin (for nerve pain) .
Emerging and Investigational Therapies
Immunomodulatory Drugs
Recent advances have led to the development of immunotherapies that target the autoimmune process in type 1 diabetes. Teplizumab, a CD3 monoclonal antibody, is the first FDA-approved immunomodulator shown to delay the onset of type 1 diabetes in high-risk individuals Ajmal2023Warshauer2019Schweiger2022. Other immunotherapies are being studied to preserve beta-cell function and potentially prevent or reverse the disease Warshauer2019Schweiger2022.
Beta-Cell Protective and Restorative Agents
New drugs are being investigated for their ability to protect or restore pancreatic beta cells. These include verapamil (a calcium channel blocker), GABA (a neurotransmitter), tauroursodeoxycholic acid (TUDCA), and volagidemab (a glucagon receptor antagonist). These agents aim to reduce inflammation and support beta-cell health Ajmal2023Von Scholten2021.
Cell-Based Therapies
Donislecel, the first FDA-approved pancreatic islet cell therapy, offers a new option for people with brittle type 1 diabetes. This therapy involves transplanting insulin-producing cells to restore endogenous insulin production, representing a significant advancement for those who struggle with severe blood sugar fluctuations .
Oral Insulin and Future Directions
Research is ongoing to develop oral insulin formulations, which could improve convenience and patient compliance. However, challenges remain due to the digestive system's barriers to insulin absorption. Strategies such as modifying insulin molecules and using absorption enhancers are being explored Nabi-Afjadi2024Von Scholten2021. Future therapies may combine immunomodulation, beta-cell protection, and advanced insulin delivery methods for more personalized and effective management Nabi-Afjadi2024Warshauer2019Von Scholten2021+1 MORE.
Conclusion
Insulin remains the cornerstone of type 1 diabetes treatment, but a growing range of adjunctive medications and innovative therapies are expanding options for patients. Advances in immunotherapy, beta-cell protection, and cell-based treatments offer hope for better disease management and, potentially, prevention or reversal of type 1 diabetes in the future Ajmal2023Affan2023Warshauer2019+2 MORE.
