Patent Summary

Preservative-free eye drops containing bimatoprost and timolol for treating glaucoma and ocular hypertension without the side effects of benzalkonium chloride preservative. The formulations aim to improve efficacy, patient compliance, and reduce ocular surface disease compared to preserved bimatoprost drops. The preservative-free drops avoid issues like hyperemia, irritation, corneal erosion, dryness, and discharge associated with benzalkonium chloride. The absence of the preservative allows use by sensitive patients and avoids contact lens absorption issues.
