What is Cequa?

Cequa known as an cyclosporine ophthalmic solution helps in producing natural tears in the eye. It is a topical solution. Hence, it is utilized for the treatment of dry eye disease.

Cequa is a calcineurin inhibitor acting as an immunosuppressant. Cyclosporine is the active component in Cequa. Cyclosporine is in the form of white powder that is insoluble in water. Cequa is utilized as a sterile, translucent, colorless eye solution for topical use.

Cequa is an anti-inflammatory agent which is a subtype of immune modulation eye drops. The tear producing glands will be damaged if the ocular surface is inflamed. Cequa eye drops work to reduce this inflammation.

Reduced inflammation will promote better functioning of tear glands and help in healing of the eye surface. Such type immune modulating eye drops can be used to treat dry eye in many autoimmune diseases like Sjögren’s syndrome1Overview| Researched based study from
