What defines Humulin N in terms of appearance and insulin classification?

Humulin N is classified as an intermediate-acting insulin and is characterized by its cloudy appearance. This insulin formulation is designed to provide a longer duration of action compared to rapid-acting insulins, making it suitable for basal insulin needs in people with diabetes. The cloudiness is due to the presence of added ingredients that cause the insulin to precipitate, resulting in a suspension that needs to be gently mixed before administration. This intermediate action profile allows Humulin N to help control blood sugar levels between meals and overnight, which is essential for maintaining overall glycemic control.

The characteristics of Humulin N emphasize its role in daily management of diabetes, as it balances out blood glucose levels when taken with short-acting insulins that are used around meal times. The understanding of these attributes is crucial for proper insulin therapy and patient education regarding diabetes management.
