There was a rapid acting inhaled insulin named Afrezza which was on the market for several years, but was recently taken off by Sanofi because it didn't sell. It is a short acting insulin to be used at meals. It is not a basal insulin, which works over 24 hours and is only injectable. I didn't like using it because of the potential for lung damage in certain populations and its side effects included coughs and sore throat. A pulmonary function study was necessary prior to use. The injectable insulin pens are easy to use and have had great patient acceptance.
