What are the 4 categories of tablets that should never be crushed and explain why?

THERE ARE BASICALLY THREE GROUPS OF medications that should never be crushed, cut in half, or chewed: ENTERIC COATED-they are coated to disslove in the intestine, otherwise it can cause gastric irritation. TIME-RELEASE CAPSULES (also called spansules) -they are meant to be released over time, otherwise it can cause an overdose. SUSTAINED-RELEASE TABLETS- they are meant to be released over time, otherwise it can cause an overdose. Some common 2 letter abbreviations after the name of the medication to indicated time-relaease or sustained release::

LA (long acting); DR (delayed release); SA (slow acting); SR (sustained release); ER (extended release). Read labels CAREFULLY. <<<ADR>>>
