*4.1.1 Rapid-acting insulin*

Insulin lispro (Humalog), insulin aspart (Novolog), and insulin glulisine (Apidra) are rapid-acting insulins. They are used as bolus (premeal or prandial) insulins. They are insulin analogs that contrast with human insulin in amino acid sequence. It binds to insulin receptors and thus functions like human insulin (**Table 4**).
