RANCHO CUCAMONGA, Calif., Nov. 07, 2018 (GLOBE NEWSWIRE) -- Amphastar Pharmaceuticals, Inc., (NASDAQ: AMPH) announced today that the U.S. Food and Drug Administration (FDA) granted approval of its New Drug Application (NDA) for Primatene Mist (epinephrine inhalation aerosol bronchodilator suspension), which is delivered by a metered dose inhaler (MDI) with a non-chlorofluorocarbon (CFC) propellant. Primatene Mist is the only FDA-approved asthma inhaler available without a prescription in the United States. Primatene Mist is indicated for the temporary relief of mild symptoms of intermittent asthma in people ages 12 and above.

Amphastar’s CEO, Dr. Jack Zhang, stated: “We are very happy to have received FDA approval for Primatene Mist and are proud to bring this important product back to the over-the-counter (OTC) market in the United States. We are grateful to the FDA team for working closely with us to make this approval possible, recognizing the important role of OTC bronchodilator drugs such as Primatene Mist. Amphastar’s mission is to develop and bring to market innovative pharmaceutical products and delivery systems that will meaningfully improve peoples’ lives and we believe Primatene Mist will do just that.”

The newly approved, patented formulation of Primatene Mist is made with the same active ingredient, epinephrine, which was used in the original Primatene Mist before it was removed from the market in 2011 for environmental reasons pursuant to the Montreal Protocol, an important international environmental treaty, which phased out products worldwide containing ozone-depleting CFCs. The product’s new inhalation delivery system no longer includes CFC as the propellant and has other significant new features, including a built-in spray indicator and a metal canister, which replaces the glass container used in the original Primatene Mist product.

According to the Centers for Disease Control and Prevention National Center for Health Statistics, approximately 20 million adults in the United States suffer from asthma. Amphastar is pleased to bring back Primatene Mist as an OTC option for the temporary relief of mild symptoms of intermittent asthma. For more information, visit www.Primatene.com.

Amphastar anticipates that Primatene® Mist will be available in major drug stores across the United States in early 2019.
