title: Analysis of the calculated physicochemical properties of respiratory drugs: can we design for inhaled drugs yet?
abstract: From an analysis of calculated physicochemical properties for 81 currently marketed respiratory drugs, compounds administered via the inhaled/intranasal routes have a higher polar surface area, a higher molecular weight, and a trend toward lower lipophilicity, when compared with their orally administered counterparts. Ranges of physicochemical space are described for the 29 drugs administered by the inhaled or intranasal routes.
