Adjusting insulin dosage for children is especially tricky due to frequent changes in body weight and insulin sensitivity as they grow. Even fast-acting insulins may not be absorbed quickly enough to get young patients to target. A new study looks at whether the Faster-acting insulin Aspart (FIAsp), which is already approved for adults and has shown good results, is safe and effective in children. It found that FIAsp can provide better mealtime glucose control for children, compared to current rapid-acting insulins.
