Enteric coating is a layer formed with a material that is less likely to be degraded in the stomach or dissolved in the stomach. Extended release dosage forms are coated with the similar layers that release the drug slowly for a certain duration of time, it is known as "controlled drug release." Drugs that are susceptible to acid degradation in the stomach or those that cause damage to the stomach are administered in the form of enteric coated drugs. Eg: Enteric coated aspirin. Drugs with shorter half-life are generally given in the form of extended release dosage forms. Eg: extended release diclofenac sodium. The enteric coated tablets are not supposed to be chewed or crushed because, they will either be degraded by the acidic environment in the stomach or cause damage to the stomach. Means, the purpose of enteric coating can't be served if they are crushed or chewed. Crushing of enteric coated tablet results in loss of the coating, so the controlled drugs release is not possible.
