Websolubility and explained by Noyes-Whitney equation. The drug with high solubility and a rapid dissolution rate is difficult to control or decrease the dissolution rate and slow its absorption. The drug with low solubility difficult to sequester a highly soluble dosage form and retard the drug release in case of high drug dose. The WebIn fact, diffusion is important not only in the body but also in some quality control procedures used to determine batch-to- batch uniformity of products (dissolution test for tablets based on the Noyes-Whitney equation, which can be derived from Fick’s law). When individual molecules move within a substance, diffusion is said to occur.
