TIGARD, Ore. — Paragon BioTeck, Inc., a privately held biopharmaceutical company specializing in the development of ophthalmic pharmaceuticals and therapies, today announced that the U.S. Food and Drug Administration has approved its New Drug Application (NDA) for Phenylephrine Hydrochloride Ophthalmic Solution, USP 2.5% and 10%, to dilate the pupil.
“This approval represents an important milestone not only for Paragon, but also within the eye care community as a whole,” said Patrick Witham, President and CEO of Paragon. “Phenylephrine Hydrochloride Ophthalmic Solution has been marketed without FDA approval for decades, and during that time has been administered to millions of patients. With the increase in drug manufacturers domestically and abroad, FDA oversight over drug products is more important than ever. The FDA approval process is in place to ensure both that a drug is safe and that it’s manufactured under appropriate controls and oversight.”
