Slow and controlled release tablets can extend the action of drugs and increase the number of times taken。 Under normal circumstances, slow and controlled release tablets need to be swallowed up, unable to break, chew or crush。 Otherwise, the dosage form will be destroyed, the dosage can not be controlled, and even a small amount of drug will be released to form a risk。 Some drugs with special explanation can be broken off and must be broken along the marked marks。
Locally sustained and controlled-release tablets (such as nifedipine controlled-release tablets) put the drug into a shell that, when fully released, is intact. After taking these drugs, if you find a pill in your stool, you don't have to worry about the quality of the pill or whether it's not absorbed.

Some enteric coated tablets, which are soothing and ineffective to gastric mucosa, are easily inactivated by gastric juice. Therefore, enteric solution should not be broken or chewed.
