ABSTRACT Introduction: Topical administration is the favored route for local delivery of therapeutic agents due to its convenience and affordability. The specific challenge of designing a therapeutic system is to achieve an optimal concentration of a certain drug at its site of action for an appropriate duration. Areas covered: This review summarizes innovations from the past 3 years (2012–2015) in the field of topical drug delivery for the treatment of local infections of the vagina, nose, eye…
