Final answer:
Lispro is a rapid-acting insulin used to lower blood sugar levels. It has a fast onset, reaches peak effect in 1-2 hours, and lasts for about 3-4 hours.
Step-by-step explanation:
Lispro is a type of drug called a rapid-acting insulin. It is used to lower blood sugar levels in people with diabetes. Rapid-acting insulins, like lispro, have a fast onset of action, meaning they begin to work quickly after injection.
The peak effect of lispro occurs about 1-2 hours after injection. This is when it is most effective at lowering blood sugar levels.
The duration of lispro is relatively short, usually lasting about 3-4 hours. This means that it is effective at lowering blood sugar for a few hours, but then its effects start to wear off.
