In brief: Insulin by inhaler: new option for diabetes treatment
Insulin by inhaler: New option for diabetes treatment
For the first time since the introduction of insulin more than 80 years ago, a non-injectable way of taking the hormone will be available. Exubera, a fast-acting inhaled insulin, was approved by the FDA in January 2006 and should be on the market by mid-year. Pfizer, which developed the drug and inhaler with Sanofi-Aventis and Nektar Therapeutics, says that a needle-free option will benefit people with diabetes who need insulin but delay treatment because they fear the injections.
More than five million people in the United States must inject insulin daily. People with type 1 diabetes, a form that usually develops at an early age, stop producing insulin. People with type 2 diabetes, which usually shows up in adulthood and is linked to obesity, continue to make insulin, but the body doesn't respond normally. This "insulin resistance" causes blood sugar to rise. Blood sugars that remain out of control can result in serious complications, including heart disease, kidney failure, vision loss, and nerve damage. Insulin therapy is the only option for people with type 1. Type 2 diabetes can usually be managed through diet, exercise, and oral medications, but some people also need insulin injections.
