Which ocular topical medication is known for causing corneal melting?

Generic Diclofenac sodium is known for its potential to cause corneal melting, particularly in cases where it is used in patients with already compromised corneal integrity or in inappropriate circumstances. Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) that works by inhibiting the cyclooxygenase (COX) enzymes, leading to a reduction in prostaglandin synthesis, which helps alleviate pain and inflammation. However, its use, especially at high concentrations or in patients with pre-existing conditions, can lead to corneal erosion or melting due to its effects on epithelial healing and corneal integrity.

In the context of corneal health, it is important for practitioners to carefully evaluate the risk versus benefit when prescribing topical NSAIDs like Diclofenac, especially for longer durations. The other topical medications listed, while they may have various side effects, are not as prominently associated with corneal melting as Diclofenac. Therefore, understanding the specific properties and risks associated with Diclofenac sodium is crucial for safe and effective ocular therapy.
