“…Local delivery via inhalation is the means of delivering therapeutics and/or other excipients directly into the lungs with their preferential accumulation in specific lung areas or regions, particularly those with afflicted or diseased cells (Kuzmov & Minko, 2015;Lam, Liang, & Chan, 2012;Resnier, Mottais, Sibiril, Le Gall, & Montier, 2016), which is predominantly useful for treating various lung diseases (Roy & Vij, 2010). For the active component(s) to be available in a respirable form, they are delivered in a liquid or solid that is suspended in a gaseous medium to form an aerosol, which is facilitated by different devices such as nebulizers or dry powder inhalers (DPIs) (Rogueda & Traini, 2007;Rubin & Williams, 2014;Ruge, Kirch, & Lehr, 2013;Zhou, Tang, Shui Yee Leung, Gar Yan Chan, & Chan, 2014).…”
