   Tony Mauro, chief business officer of Mylan, commented that for the first generic drug launch of Advair Diskus, we have made a huge discount to improve the affordability of the health care system. It is believed that through this, we can save a considerable amount of out-of-pocket expenses for patients, and at the same time save a lot of cost for the US health system.

   According to data from the National Heart, Lung, and Blood Institute, asthma affects people of many ages and is more common in children. There are approximately 26 million asthma patients in the United States, of which 7 million are children. COPD is a chronic progressive disease that causes symptoms such as sputum, cough, wheezing, shortness of breath, and chest tightness.
 
   Advair Diskus is a combination of drugs and devices, and the development of such inhaler imitation products is far more difficult than oral solid preparations. The FDA also recognizes the challenges faced by generics companies in developing such complex generic products, including when to load drugs into inhalation devices. In 2013, the FDA released a guide to the development of generic products for Advair, providing some considerations for biosimilars, prescriptions, and device devices for such generics. In addition, the FDA has inspected the production and packaging facilities of generic manufacturers to ensure they are able to produce products that meet strict quality standards.

The FDA will continue to help the industry advance the development of complex generic products by issuing new policies and guidelines. recent. The FDA has issued 27 guidance documents to guide the development of some generic products for transdermal and topical delivery.
