The term "diffusible" in literature is often used to describe substances that possess the ability to spread or disseminate rapidly, thereby exerting their effects throughout a system. For instance, in one work, it is applied to a stimulant that readily diffuses within the body, enhancing its therapeutic impact [1]. In another context, the word emphasizes not only the prompt action of the stimulant but also its antiseptic properties and capacity to facilitate elimination, highlighting its multifaceted role in bodily functions [2].
