Background:
Type 2 diabetes mellitus (T2DM) is a leading cause of morbidity and mortality that places a substantial economic and health burden on the public. Successful management of T2DM requires strict control of glycemia as well as other risk factors to prevent disease progression. Despite the availability of multiple classes of oral antidiabetic drugs and insulin, the majority of patients fail to attain or maintain tight glycemic control over time, raising their risk of serious microvascular and macrovascular complications.
Scope:
This review briefly outlines current standards of diabetes treatment and explores several new and investigational approaches. It is based on MEDLINE literature searches (1966-August 2006) and on abstracts from the American Diabetes Association Scientific Sessions (2002-2006) and the European Association for the Study of Diabetes Annual Meetings (1998-2006). Articles concerning basic science, preclinical, and clinical trial results were selected for this review based on their originality and relevance.
Findings:
Medical professional societies and other specialist groups have proposed a series of practical steps to enable more patients with T2DM to reach treatment goals. Among their most important recommendations is a call for new drugs to stabilize or reverse the progressive pancreatic islet-cell dysfunction that characterizes the disease. New modalities, such as incretin mimetics and DPP-4 inhibitors, are now emerging from clinical development and will provide patients with more treatment options.
Conclusions:
It appears likely that early and aggressive treatment with multiple drug combinations will become more common in the management of T2DM. The new treatment modalities discussed here offer hope for improved outcomes and for meeting the considerable public health challenges posed by this complex condition. However, long-term studies are needed to determine durability of treatment effects, as well as the ultimate role of these new agents in the management of patients with T2DM.
Insights
Type 2 diabetes mellitus (T2DM) management faces challenges with current treatments. New therapies like incretin mimetics and DPP-4 inhibitors offer improved options for glycemic control and disease progression.
Area of Science:
- Endocrinology and Metabolism
- Pharmacology
- Public Health
Background:
- Type 2 diabetes mellitus (T2DM) is a major cause of illness and death, imposing significant burdens.
- Effective T2DM management requires strict glycemic control and management of other risk factors to prevent complications.
- Many patients struggle to achieve or maintain optimal glycemic control with existing oral antidiabetic drugs and insulin.
Purpose of the Study:
- To review current standards for T2DM treatment.
- To explore emerging and investigational therapeutic approaches for T2DM.
- To identify new drug classes that may improve patient outcomes.
Main Methods:
- Literature review of MEDLINE (1966-2006) and major diabetes conference abstracts (2002-2006).
- Selection of original and relevant articles on basic science, preclinical, and clinical trial results.
- Focus on practical recommendations and novel therapeutic strategies.
Main Results:
- Professional societies recommend practical steps to improve patient treatment outcomes.
- New drug development is crucial to address progressive pancreatic islet-cell dysfunction in T2DM.
- Incretin mimetics and DPP-4 inhibitors are emerging as promising new treatment options.
Conclusions:
- Early and aggressive combination therapy is likely to increase in T2DM management.
- Novel treatment modalities offer potential for better outcomes and addressing public health challenges.
- Long-term studies are essential to evaluate the durability and role of new T2DM agents.
