Which latanoprost brand name is known to be benzalkonium chloride-free?

Explanation:
Understanding preservative content in latanoprost formulations helps explain why a benzalkonium chloride-free option matters. Benzalkonium chloride (BAK) is a common preservative in glaucoma drops, but it can irritate the ocular surface, contribute to dryness, and cause toxicity with long-term use. Xelpros is the latanoprost brand specifically formulated without benzalkonium chloride, making it a suitable choice for patients who are sensitive to BAK or have ocular surface disease. The other brands listed are not known for being benzalkonium chloride-free, as they use traditional preservatives or alternative systems that do not guarantee a BAK-free formulation. So, when avoiding BAK is the goal, Xelpros stands out as the best option.
