## Core Concept
Afrezza is a rapid-acting inhaled insulin product used for the control of high blood sugar in adults with type 1 and type 2 diabetes. It works by delivering insulin directly to the lungs, where it is absorbed into the bloodstream. This method allows for a quicker onset of action compared to traditional insulin injections.

## Why the Correct Answer is Right
Afrezza utilizes a proprietary Technosphere technology that allows insulin to be absorbed quickly into the bloodstream through the lungs. This results in a rapid onset of action, typically within 12-15 minutes, making it suitable for use at mealtimes to manage postprandial glucose spikes. Its unique delivery mechanism and rapid action are key benefits for patients who struggle with injectable insulin or need more flexibility in their diabetes management.

## Clinical Pearl / High-Yield Fact
A key point to remember about Afrezza is that it is not a substitute for long-acting insulin. Patients with type 1 diabetes will still require a long-acting insulin for basal glucose control. Afrezza is specifically designed to manage glucose spikes immediately following meals.
