Insulin: either alone or combined with oral hypoglycemic agents

Area of Science:

• Endocrinology
• Metabolic Disorders
• Pharmacology

Background:

• Non-insulin-dependent diabetes mellitus (NIDDM) is characterized by insulin resistance and deficiency, leading to hyperglycemia.
• Current therapeutic approaches aim to correct these underlying defects to improve glucose metabolism.

Purpose of the Study:

• To review and discuss therapeutic strategies for managing NIDDM, focusing on insulin and sulfonylurea treatments.
• To outline individualized treatment goals based on patient age, comorbidities, and disease severity.

Main Methods:

• Review of existing evidence on the efficacy of sulfonylureas and insulin in NIDDM management.
• Discussion of treatment approaches, including diet, exercise, oral agents, and various insulin regimens.
• Consideration of specific patient populations, such as those with severe NIDDM, insulin resistance, or concurrent illnesses.

Main Results:

• Both sulfonylureas and insulin can achieve glycemic control (normal FPG and HbA1c) in mild to moderate NIDDM.
• Insulin therapy, particularly soluble preprandial insulin, may be necessary for post-prandial hyperglycemia control.
• Treatment strategies should be tailored to individual patient needs, considering factors like age, comorbidities, and social support.

Conclusions:

• Therapy for NIDDM should address both insulin resistance and deficiency.
• Individualized treatment goals and regimens, including diet, exercise, sulfonylureas, and various insulin types, are essential for effective management.
• Combination therapy may be considered for patients not achieving control with monotherapy.
