  • Ensuring Better Control of Granulation
    granulation grows more complex each year. This article reviews the most current methods and mechanisms of pharmaceutical granulation, including factors that can lead to improved control. a) Adhesion and cohesion forces in immobile films. If sufficient liquid is present in a powder to form a thin, immobile...
