Amphastar Receives FDA Approval for Albuterol Sulfate Inhalation Aerosol

RANCHO CUCAMONGA, CA / ACCESSWIRE / May 22, 2024 / Amphastar Pharmaceuticals, Inc. (NASDAQ:AMPH) today announced that the U.S. Food and Drug Administration ("FDA") has granted approval for the Company's Abbreviated New Drug Application ("ANDA") for Albuterol Sulfate Inhalation Aerosol, previously known as AMP-008. This product is for the treatment or prevention of bronchospasm in patients four years of age and older with reversible obstructive airway disease and the prevention of exercise-induced bronchospasm in patients four years of age and older. The FDA determined that Amphastar's albuterol is bioequivalent and therapeutically equivalent to Teva Respiratory LLC's ProAir^® HFA (albuterol sulfate) Inhalation Aerosol.

Amphastar's CEO and President, Dr. Jack Zhang, commented: "Our first generic inhalation product's approval reflects both our technological and manufacturing ability. While patients can benefit from increased access to this combination drug product, we are proud to manufacture the finished product in the United States, as our commitment to quality remains our top priority. This approval sets a solid foundation for future growth in developing our other generic inhalation products, highlighting our expertise in developing complex products."

According to IQVIA, the U.S. sales for the branded and generic albuterol sulfate Inhalation Aerosol products were approximately $1.7 billion for the 12 months that ended March 31, 2024.
