Webb24 juli 2015 · Jul 24, 2015. Advances in delivery methods renewed interest in the development of an inhaled form of insulin. We explore the history, pros and cons, and future of this fast-acting, short-duration drug. Interest in inhaled insulin isn’t really new. The concept was first studied in 1924, soon after the discovery of insulin itself. WebbInhaled formulations of the micronized drugs (<5 μm) include dissolved/suspended drug particles in a suitable solvent (suspensions or emulsions) or powder formulation mixed … WebbDespite the limited knowledge about the inhaled particles at the WTC disaster site, and the almost total absence of information about volatile compounds, the hydrosolubility and size characteristics of the particles make them plausible irritants, capable of causing inflammatory mucosal changes throughout the respiratory tract. register later flow test scotland
