Pfizer ( PFE) found the answer to be a resounding "No" when the launch of its Exubera inhaled insulin device crashed and burned soon after hitting the market in 2006. Diabetes patients found the insulin dosing required for Exubera to be confusing, concerns about lung problems lingered, and the design of the Exubera device was embarrassingly bad. It looked exactly like a medium-sized bong -- not exactly something diabetics wanted to carry around with them.
