FDA OKs an inhaled version of smoking cessation drug Chantix — for a common eye disease

Oyster Point Pharma now has its first FDA-approved product — Tyrvaya. And the biotech has taken a unique route to get there by using an old drug with a storied past.

The New Jersey biotech announced this morning that the FDA has approved their nasal spray product for dry eye disease on Friday — the first nasal spray to be approved for the disease. The product’s active ingredient is 0.03 mg of varenicline, also known as smoking cessation aid Chantix.
