Efficacy and Tolerability of Preservative-free 0.0015% Tafluprost in Glaucoma Patients

Benzalkonium chloride (BAK) is the most used preservative and is excellent for safety and stability of drug. However, it causes dry eye, corneal oedema, corneal erosion, and corneal toxicities, thus lowering the long-term tolerability for patients. A critical component when managing glaucoma patients is ensuring compliance.

Tafluprost (trade names Taflotan or Taflotan-S by Santen Pharmaceutical) is a prostaglandin analogue. It is used topically (as eye drops) to control the progression of open-angle glaucoma and in the management of ocular hypertension. In this study, tafluprost was used in all experimental group with equally concentration(0.0015%), only measured whether BAK was included or not.
