[Intraindividual double-blind comparative study of the immediate ocular tolerability of the Na+ and Mg++ salts of N-acetyl-aspartylglutamic acid (NAAGA)].
A good immediate ocular tolerance of eye-drops is paramount for the patient's compliance, and therefore for the therapeutic success. The tolerance of a new formula of NAAXIA, an anti-allergic eye-drop, whose sole modification was the replacement of the Mg++ ion by the Na+ ion, was compared with the previous formula. One drop of each preparation was instilled in one eye so as to make an intraindividual comparison. Just after instillation, each subject was asked to express what he felt, and which eye-drop he preferred. The answers, reported on a sequential analysis graph, clearly show that in all three groups (healthy adults, red-eyed adults, red-eyed children) the slight alteration of the formula led to a marked improvement in immediate tolerance.
