A patient has a history of IDDM. Which medication could be prescribed for managing this condition?

Humalog is an insulin analog specifically designed for the management of diabetes mellitus, particularly for individuals with Type 1 Diabetes Mellitus (IDDM). This medication is a rapid-acting insulin that works quickly to help manage blood glucose levels, especially after meals. It acts by mimicking the natural hormone insulin, facilitating the uptake of glucose by cells and lowering blood sugar levels more effectively when consumed with food.

Patients with IDDM often require insulin therapy to maintain glycemic control, particularly because their bodies do not produce insulin on their own. Humalog's formulation allows for flexibility in dosing and timing, making it suitable for those needing to adjust their insulin based on carbohydrate intake and activity levels throughout the day.

In contrast, other options such as Metformin and Glyburide are primarily used for Type 2 Diabetes Mellitus management and may not be appropriate for patients with IDDM, as they rely on different mechanisms and do not replace the need for insulin. Novolog is also a correct choice as a rapid-acting insulin similar to Humalog, but the context establishes Humalog as the selected option for this particular scenario.
