The greatest advantage of prodrugs is the potential to add groups that mask features of the drug molecule that prevent penetration or have other undesirable effects. Prodrug design can be a useful way of increasing penetration of a therapeutic agent through corneal or other barriers. A pair of pivalyl groups is attached to the two charged groups on epinephrine. The epithelial penetration is increased 10-fold by this diesterification because of the lipophilic nature of the modified prodrug. Thus, a topically applied dipivalyl derivative need only be one-tenth the concentration of epinephrine to achieve bioavailability equivalent to epinephrine.

In many cases of superficial inflammation, a lubricating eyedrop without preservatives may be the best course of treatment.
