Nephron Pharmaceuticals makes its racepinephrine-containing Asthmanefrin, previously marketed only to health care professionals, available as the only OTC inhaler. The product likely will be alone on the market until Amphastar Pharmaceuticals’ planned launch in 2013 of a reformulated Primatene Mist inhaler.
