[5] It is delivered subcutaneously either by injection or from an insulin pump. [5] [6] Onset of effects typically occurs within 30 minutes and lasts about 5 hours. [5]
NPH insulin is cloudy and has an onset of 1–3 hours. Its peak is 6–8 hours and its duration is up to 24 hours. [9]It has an intermediate duration of action, meaning longer than that of regular and rapid-acting insulin, and shorter than long acting insulins (ultralente, glargine or detemir).
The insulin aspart protamine portion is a crystalline form of insulin aspart, which delays the action of the insulin, giving it a prolonged absorption profile after injection. [14] The combination of the fast-acting form and the long-acting form allows the patient to receive fewer injections over the course of the day. [27]
Regular insulin should be given with about a 30-minute lead-time prior to the meal to be maximally effective and to minimize the possibility of hypoglycemia. Lispro, aspart and glulisine are approved for dosage with the first bite of the meal, and may even be effective if given after completing the meal.
It is administered once daily and has a duration of action that lasts up to 40 hours (compared to 18 to 26 hours provided by other marketed long-acting insulins such as insulin glargine and insulin detemir). [6] [7] The change involves attachment of a hexadecanedioic acid tail to the B29 lysine's "tail" nitrogen. This allows the molecule to ...
A fast-reacting drug means insulin injections do not have to precede mealtimes by hours, which in turn gives people with diabetes more flexibility in their daily schedules. [47] Insulin can aggregate and form fibrillar interdigitated beta-sheets. This can cause injection amyloidosis, and prevents the storage of insulin for long periods. [48]
