Oil suspended phenylephrine

摘要

An oil suspension, preferably sesame seed oil suspension, of the base form of phenylephrine as an opthalmic medicament. Surprisingly, the base form of phenylephrine is much quicker absorbed into the eye than the conventional acid salt form. As a result, lower dosage levels can be used to achieve the same mydriatic effect, thus reducing the risk of adverse side effects from systemic absorption.
