Dose dumping is defined as "Unintended, rapid drug release in a short period of time of the entire amount or a significant fraction of the drug contained in a modified release dosage form1." A sustained/extended/controlled release dosage form is intended to release the drug in desired concentrations for a prolonged period of time. A dosage form is said to be dose dumped when there is an excess release of drug at a particular time interval other than the stated or required amount. This results in higher systemic drug concentrations that may result in toxicity.
