Which topical NSAID is known to have thimerosal as its main preservative and NOT BAK?

Flurbiprofen, marketed as Ocufen, is a topical non-steroidal anti-inflammatory drug (NSAID) that is used in ophthalmology primarily to manage pain and inflammation associated with ocular surgery. One of the distinguishing characteristics of Flurbiprofen is its use of thimerosal as a preservative, rather than benzalkonium chloride (BAK), which is commonly found in many other topical ophthalmic medications.

Thimerosal is a mercury-containing compound that serves as an effective antimicrobial preservative, and its presence in Flurbiprofen makes it the choice when seeking a NSAID preserved with thimerosal. This characteristic is particularly relevant for patients with sensitivities or allergies to BAK, providing an alternative that can mitigate potential adverse effects from the more commonly used preservative.

In this context, Flurbiprofen stands out among the options provided, as the other NSAIDs mentioned typically contain BAK or do not specifically use thimerosal as a preservative. Understanding the composition and preservative content of ophthalmic medications is crucial for both patient safety and effective management of ocular conditions.
