Methods for measurement of solubility and dissolution rate of sparingly soluble drugs 7 where dw dt is the dissolution rate, D is the diffusion constant, CS and C are the solubility and bulk concentration respectively, A is the surface area and h is the diffusion layer thickness. It is possible for some substances to dissolve in a higher concentration than could be attained at equilibrium, have increased solubility, and form supersaturated solutions.
