Humulin is a synthetic form of human insulin that is used to manage diabetes. It is designed to mimic the actions of insulin produced by the pancreas, a vital organ responsible for regulating blood sugar levels. By providing exogenous insulin, Humulin helps individuals with diabetes maintain appropriate glucose control and prevent complications associated with high or low blood sugar levels.

Humulin has a rich history in the field of insulin therapy. Developed by scientists at Genentech and Eli Lilly and Company, Humulin was the first biosynthetic human insulin approved by the United States Food and Drug Administration (FDA) in 1982. Prior to Humulin, insulin was derived from animal sources, which posed challenges in terms of availability and potential allergic reactions. With the advent of Humulin, insulin therapy became more accessible and safer for individuals with diabetes.

Humulin is produced using recombinant DNA technology, ensuring its purity and consistency. This manufacturing process eliminates impurities and variations often present in animal-derived insulins. The high purity and consistency of Humulin contribute to its predictable and reliable action, providing individuals with better control over their blood sugar levels.

Humulin works by replacing or supplementing the natural insulin in the body. When injected subcutaneously, it enters the bloodstream and travels to the cells throughout the body. Once there, it binds to insulin receptors on the cell surface, allowing glucose to enter the cells and be utilized for energy production. This process helps lower blood sugar levels and maintains a balanced glucose metabolism.

Humulin Products

Humulin insulin offers individuals with diabetes different options to effectively manage their blood sugar levels. Humulin N provides basal insulin coverage, Humulin R helps control blood sugar levels after meals, and Humulin 30/70 offers a convenient premixed insulin solution. Each type has its unique benefits and usage considerations.

Humulin N

Humulin N is an intermediate-acting insulin that provides a steady release of insulin to control blood sugar levels between meals and during the night.  It contains NPH (Neutral Protamine Hagedorn) insulin, which has an onset of action within 1 to 3 hours, peaks in 8 to 12 hours, and can last up to 24 hours. It has a slower onset of action compared to rapid-acting insulins, making it effective in providing basal insulin coverage. Humulin N is typically administered as an injection, allowing it to help regulate blood sugar levels between meals and overnight. It is usually administered once or twice a day, depending on the individual’s specific requirements. It helps maintain stable blood sugar levels throughout the day and night.

Humulin R

Humulin R is a short-acting insulin that is commonly used to control blood sugar spikes after meals. Its onset of action occurs within 30 minutes to 1 hour, reaches its peak in 2 to 3 hours, and generally lasts for around 4 to 6 hours. Humulin R is often used in combination with longer-acting insulins or oral medications to control blood sugar levels after meals. It is available in vials, cartridges, and prefilled pens for convenient administration.

Humulin 30/70

Humulin 30/70 is a premixed insulin that combines the benefits of both short-acting and intermediate-acting insulin. It consists of 30% Humulin R (short-acting) and 70% Humulin N (intermediate-acting). This combination offers a more convenient option for individuals who require both types of insulin. Humulin 30/70 has a faster onset of action compared to Humulin N alone, helping to manage blood sugar levels effectively throughout the day. Humulin 30/70 is beneficial for individuals who require a convenient dosing regimen and have consistent meal schedules. This premixed insulin offers a balanced coverage of insulin needs throughout the day, helping maintain stable blood sugar levels.

Key Differences

Although all three types of Humulin insulin are effective in managing diabetes, there are some key differences worth noting. Humulin N is an intermediate-acting insulin, Humulin R is a short-acting insulin, and Humulin 30/70 is a premixed insulin. The main difference lies in their onset of action, peak times, and duration of effectiveness.
