Arizona Tribune - Amphastar Announces FDA Approval for Ipratropium Bromide HFA

Additionally, the FDA has confirmed that this product is eligible for 180-days of generic drug exclusivity for Ipratropium Bromide HFA Inhalation Aerosol as we were the first ANDA applicant with Paragraph IV certification. This exclusivity period will begin on the first day that Amphastar's Ipratropium Bromide HFA Inhalation Aerosol is commercially launched.

"We are excited to announce FDA approval of Ipratropium Bromide HFA Inhalation Aerosol, reinforcing the strength of our integrated R&D and manufacturing model and demonstrating our ability to deliver complex, high-value generics," said Dr. Jack Zhang, Amphastar's President and Chief Executive Officer.
