Used primarily in ophthalmology, the chemical is a P2Y2 receptor agonist that stimulates fluid and mucin secretion on the ocular surface. It is applied as eye drops to treat dry eye disease by enhancing tear production and improving the stability of the tear film. By promoting both aqueous and mucin components of tears, it helps maintain corneal health, reduces symptoms like dryness, irritation, and discomfort, and supports the healing of the ocular surface. Its action addresses the multifactorial nature of dry eye, making it effective in cases where tear deficiency is a key component.
