Brief summary

Phase I Study to evaluate safety and tolerability of PRO-185 (naphazoline/hypromellose) ophthalmic solution through evaluation of vital signs, ocular signs such as intraocular pressure, hyperemia and mydriasis and adverse events.

Detailed description

A total of 22 healthy volunteers will apply PRO-185 ocular solution on both eyes QID (four times per day) for 8 days. The safety variables will include intraocular pressure, heart rate, systolic and diastolic blood pressure. Tolerability variables will include: hyperemia, mydriasis, and expected and unexpected adverse events. The presence of any of these in ≤ 20% will deem PRO-185 as safe and tolerable.
