Insulin Delivery Systems: An Overview
A rapid-acting inhaled insulin is also FDA-approved for use before meals.
Timing. The drug peaks in the blood in about 15-20 minutes, researchers say, and clears the body in 2-3 hours.
Needle-free. Users place a dose insulin, in powder form, into a small, whistle-sized inhaler. Doses come in a cartridge, and each cartridge contains a single dose.
More insulin needed. Inhaled insulin can be used for both type 1 and type 2 diabetes, however, it must be used in combination with long-acting insulin in patients with type 1 diabetes.
Risks. Inhaled insulin should not be used by those who smoke or have chronic lung disease.
