Chitosan solubility in citric acid
WebThe use of an amorphous drugs system to generate supersaturated solutions is generally developed to improve the solubility and dissolution of poorly soluble drugs. This is because the drug in the supersaturation system has a high energy state with a tendency to precipitate. In the amorphous solid dispersion (ASD) formulation, it was discovered that … WebDec 10, 2024 · And: chitosans are environment-friendly and consumer-safe, non-toxic and non-allergenic, biodegradable and biocompatible in many systems [ 1 ]. Of course, not all chitosans possess all of these properties and bioactivities. The functional diversity is based on an equally broad structural diversity.
