Volumes is often problematic when deciding by far the most appropriate dissolution test to work with, stresses Eckert. The commonly employed apparatus are confined to be used with media volumes of involving 500 mL and one thousand mL, which often can prohibit the physiological relevance. Even so, using substantial volumes for dissolution testing may result in an overestimation of in-vivo
