You may have felt a dry feeling in your eyes, like a grain of sand stuck inside, or just a red, burning sensation. We call this 'Dry Eye Disease'. This condition can occur in people who spend a lot of time looking at the computer, in people with certain diseases, as they age, and for many other reasons. So today we are going to talk about a new nasal spray that doctors have introduced as a treatment for this. The special thing about this is that it is not a medicine that is applied to the eyes, but a nasal spray.
What is this Varenicline nasal spray?
Simply put, this is a medicine that treats a condition called Dry Eye Disease. It can be found in the market under the name `(Tyrvaya)`. The surprising thing about this is that it is not a medicine that is applied to the eyes, but a nasal spray. Imagine how dry eyes can be cured by spraying a medicine into the nose.
Here's how it works: There's a nerve inside our nose that's directly connected to the glands that produce tears in our eyes. When you spray this medicine called `Varenicline` into the nose, it stimulates that nerve. That stimulation causes our body to produce more tears naturally. This way, instead of using artificial tears, the medicine works by moistening your eyes with the natural tears your body produces, reducing dryness.
