Dissolution Test

Drug dissolution test is a standardized method for measuring the release rate of a drug from a given dosage form, which helps to evaluate the performance of a drug, because the rate and degree of drug absorption depend on its dissolution from the formulation. In the pharmaceutical industry, drug dissolution test is usually used for quality control to ensure consistency between production batches.
