Introduction
Insulin aspart injection acts rapidly, beginning to work 10 to 20 minutes after injection, effectively lowering postprandial blood glucose levels. Its duration of action is relatively short, typically lasting 3 to 5 hours, making it suitable for administration before meals to promptly address the rise in blood glucose following food intake. Compared with long-acting insulin, insulin aspart injection does not provide a continuous basal insulin effect.
Insulin aspart, also known as insulin aspart injection, is typically a short-acting insulin. The detailed explanation is as follows:
Insulin aspart injection works rapidly, beginning to take effect 10 to 20 minutes after injection, effectively lowering post-meal blood glucose levels. Its duration of action is relatively short, usually lasting 3 to 5 hours. It is suitable for administration before meals, allowing timely management of elevated blood glucose following food intake.
Compared with long-acting insulin, insulin aspart injection lacks a continuous and stable basal effect and cannot maintain stable blood glucose levels throughout the day. The dosage must be adjusted according to meal timing and food quantity to match postprandial glucose fluctuations, thereby preventing hypoglycemia or inadequate glycemic control.
Strict control of injection timing and dosage is essential when using insulin aspart injection. Patients should eat promptly after injection and regularly monitor blood glucose levels to ensure stable glycemic control.
