Crushing modified-release dosage forms may lead to which potential outcome?

• A. Improved taste
• B. Rapid, total dose release causing potential harm
• C. Better absorption
• D. They become more stable

Answer: (B)

Modified-release dosage forms are designed to release the drug gradually over time. Crushing them destroys the controlled-release mechanism—whether it’s a coating, a polymer matrix, or an osmotic system—so most or all of the drug is released at once. This dose-dumping spike in drug levels can lead to toxicity and harm, especially with medications that have narrow therapeutic windows or significant overdose risk. That’s why the outcome described as rapid, total dose release causing potential harm is the correct understanding. While taste changes or other factors can occur with crushing, the critical safety issue is the loss of controlled release and the resulting sudden surge in drug exposure. Crushing also does not make the drug more stable; in fact, it can reduce stability and protection from the environment.
