The characteristics of drug particles are closely tied to product quality, performance, and manufacturing processes, directly determining the final therapeutic efficacy. Particle size, shape, distribution, and surface properties influence dissolution rate, stability, bioavailability, and release behavior within the body. For example, smaller particles can enhance drug solubility and absorption efficiency, while uniform distribution aids in consistent dispersion and stable storage. During drug development and production, precisely controlling particle preparation processes optimizes drug performance.
Microscopic analysis techniques like SEM can visually present the surface morphology and internal structure of drug particles. Combined with EDS, it enables qualitative and quantitative analysis of particle composition, providing essential technical support for drug quality control and process optimization.
