Three formulations were evaluated: 200\u2009mg of spray-dried ciprofloxacin formulation for respiratory infection, 200\u2009mg of spray-dried mannitol formulation for mucus clearance, and 100, 200, and 400\u2009mg of co-spray-dried 1:8 formulations containing ciprofloxacin and mannitol as combination therapy. The systems were evaluated in terms of physicochemical properties and tested using a multistage liquid impinger at 60 L\/min. Emptying rates were evaluated, and the aerosolization performance compared with 10 capsules used sequentially in the RS01.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results and Discussion:<\/jats:title>\n                    <jats:p>The systems were different in terms of morphology, thermal response, moisture sorption, and stability; however, they had similar sizes when measured by laser diffraction, making them suitable for comparison in the Orbital and RS01 devices. The aerosolization performance from the Orbital device and RS01 was dependent on the formulation type; however, the fine particle fraction (FPF) produced by the Orbital device was higher than that by the RS01. The FPFs for ciprofloxacin, mannitol, and co-spray-dried formulation were 67.1\u00b11.8, 47.1\u00b12.2, and 42.0\u00b11.8, respectively. For the Orbital, 90% of the loaded dose was delivered within 10 inhalation maneuvers, with the profile being dependent on the formulation type.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The Orbital provides a means of delivering high doses of medicine to the respiratory tract through multiple breath maneuvers after a single actuation. This approach will allow the delivery of a wide range of high-payload formulations (&gt;100\u2009mg) for the treatment of a variety of lung disorders. To date, no such passive device exists that meets these crucial criteria.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/jamp.2013.1080","type":"journal-article","created":{"date-parts":[[2013,9,4]],"date-time":"2013-09-04T10:44:23Z","timestamp":1378291463000},"page":"138-147","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":38,"title":["Overcoming Dose Limitations Using the Orbital\n                    <sup>\u00ae<\/sup>\n                    Multi-Breath Dry Powder Inhaler"],"prefix":"10.1177","volume":"27","author":[{"given":"Paul M.","family":"Young","sequence":"first","affiliation":[{"name":"The University of Sydney","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Crapper","sequence":"additional","affiliation":[{"name":"Pharmaxis Ltd.","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary","family":"Philips","sequence":"additional","affiliation":[{"name":"Pharmaxis Ltd.","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ketan","family":"Sharma","sequence":"additional","affiliation":[{"name":"The University of Sydney","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hak-Kim","family":"Chan","sequence":"additional","affiliation":[{"name":"University of Sydney","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Traini","sequence":"additional","affiliation":[{"name":"The University of Sydney","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,9,4]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1615\/CritRevTherDrugCarrierSyst.v12.i2-3.20"},{"key":"e_1_3_3_3_2","first-page":"53","article-title":"Systemic treatment by inhalation of macromolecules\u2014principles, problems, and examples","volume":"59","author":"Siekmeier R","year":"2008","unstructured":"Siekmeier R, , and Scheuch G: Systemic treatment by inhalation of macromolecules\u2014principles, problems, and examples.
