Insulin is classified based on its onset, peak, and duration of action. Commercially available insulins fall into four main categories:
- Rapid-acting
- Short-acting
- Intermediate-acting
- Long-acting
Here's a breakdown of each type:
Types of Insulin
The different types of insulin are designed to mimic the body's natural insulin release patterns in response to meals and to provide a basal level of insulin coverage.
| Insulin Type | Onset of Action | Peak Time | Duration of Action |
|---|---|---|---|
| Rapid-Acting | ~15 minutes | 1-2 hours | 3-5 hours |
| Short-Acting | ~30 minutes | 2-4 hours | 5-8 hours |
| Intermediate-Acting | 1-2 hours | 4-12 hours | 12-18 hours |
| Long-Acting | Several hours | No pronounced peak | 24 hours or longer |
Key Considerations:
- Individual Needs: Insulin regimens are highly individualized. The best type or combination of insulins depends on a person's lifestyle, diet, and blood glucose levels.
- Medical Advice: Always consult a healthcare professional for advice on insulin therapy.
- Reference: Commercially available insulins are categorized as rapid-acting, short-acting, intermediate-acting, and long- acting.15-Feb-2023
