We assessed the anti-inflammatory, anti-oxidative and anti-remodeling impacts of a synthesized myrtenol-loaded niosome in rats with allergic asthma. Forty-nine rats were divided into seven groups of control, vacant niosome (VN), Asthma, Asthma+VN, Asthma+SM (simple myrtenol), Asthma+NM (niosomal myrtenol, 8 mg/kg), and Asthma+B (budesonide, 41 μg).
