AptarGroup, Inc. announced that its patented Cartridge Pump System (CPS), designed for the multidose delivery of preserved and non-preserved drug formulations, was recently reviewed by the U.S. FDA as the drug delivery device in the approval of Oyster Point Pharma?s TYRVAYA? (varenicline solution) Nasal Spray 0.03 mg, the first and only nasal spray approved for the treatment of the signs and symptoms of dry eye disease. TYRVAYA?, a highly selective cholinergic agonist, is the first nasally-administered pharmaceutical therapy to treat the signs and symptoms of dry eye disease to have been approved by the U.S. FDA. This approval makes Aptar?s Cartridge Pump System a key component of the first and only U.S. FDA-approved pharmaceutical therapy to deliver treatment for the signs and symptoms of dry eye disease, an ophthalmic condition, via the nasal route and re-confirms Aptar?s expertise for developing innovative drug delivery solutions.
