The "power" of an insulin formulation often refers to its concentration. Higher concentration means a smaller volume delivers the same number of insulin units, which can be important for some patients.
Based on the reference provided, different insulin strengths exist: U-100, U-200, U-300, and U-500. The reference notes that U-500 insulin is the most concentrated, and therefore the most "powerful," as it delivers five times more insulin per milliliter than U-100 insulin.
| Insulin Type | Units per mL | Relative Concentration |
|---|---|---|
| U-100 | 100 | 1x |
| U-200 | 200 | 2x |
| U-300 | 300 | 3x |
| U-500 | 500 | 5x |
In summary, U-500 insulin is more powerful due to its higher concentration.
