I know you have many patients, but given the fact that apraclonidine is used for postsurgical intraocular pressure prevention or treatment, you can't have that many on it. It is also not generally used for pediatrics.
Given the fact the program has the ability to change all medications instantly that match what was selected, it would seem like it would have the ability to immediately change them back if necessary.
It would be really cool if it were patient specific, e.g. Please find all patients whose meds were changed after certain medication was changed to apraclonidine on patient ID# 1234.
