Abstract
The present invention discloses a rhodomyrtone inhalation suspension and a preparation method thereof. The rhodomyrtone inhalation suspension is obtained by mixing the following raw materials and auxiliary materials in percentage by weight: rhodomyrtone 0.02%-1%, surfactant 0.005%-0.1%, suspending agent 0-2.2%, pH regulator 0.01%-0.03%, flocculant 0.02%-0.04%, stabilizer 0.005%-0.015%, osmotic pressure regulator 0.7%-1.1%, and water as the balance; the surfactant is polysorbate; and the suspending agent is povidone K30 and / or microcrystalline cellulose-sodium carboxymethylcellulose. The inhalation suspension has a high effective lung deposition rate and accurate delivery dose, and can accurately deliver a set dose of rhodomyrtone directly to lung lesions, exerting its antiviral efficacy.
