Explanation:
Detailed explanation-1: -Insulin has a short plasma half-life (4–6 min), as would be expected from the necessity to respond rapidly to changes in blood glucose (2, 7).
Detailed explanation-2: -After secretion from the pancreas, the estimated biological half-life of insulin in the blood stream lies between 3 and 10 min.
Detailed explanation-3: -Actrapid is a fast-acting insulin. Onset of action is within ½ hour, reaches a maximum effect within 1.5-3.5 hours and the entire duration of action is approximately 7-8 hours. Insulin in the blood stream has a half-life of a few minutes.
