METHOD FOR SELECTING THE CONCENTRATION OF AN AMPHIPATHIC ANTIHISTAMINE DRUG BY DETERMINING THE DRUG'S SURFACE ACTIVITY RATING

摘要

Topical ophthalmic anti-allergy drugs are identified by the extent of their interaction with a phospholipid model membrane. Disclosed are topically administrable ophthalmic formulations containing amphipathic anti-allergy compounds at concentrations such that the drugs have Surface Activity Ratings from about 2-11.
