Apraclonidine 0.5% reduces IOP by what percentage?

Explanation:
Apraclonidine 0.5% lowers intraocular pressure mainly by reducing aqueous humor production through stimulation of alpha-2 receptors in the ciliary body. In practice, a single topical drop typically produces a substantial drop, about 30% or more from baseline, with many sources citing around 30–40% and some patients approaching the higher end of that range. That makes the 30–40% range the best fit among standard values for this medication. A smaller decrease, around 10–20%, would be less characteristic for apraclonidine at this concentration. A very modest 5–15% drop is even less consistent, and a 50–60% reduction would be unusually large for a single drop in routine use.
