Why learn generic drug suffixes? Memorizing drug names is one of the most challenging parts of pharmacology.
One thing to consider and embrace is that there is some lingo in pharmacy. In generic names, there are several
suffixes that will help you to remember what the medication does. In this case, the suffixes are a group of letters
added to the end of a words root which help better describe its function. The chart below lists some of the most
common suffixes you will see. Learn the commonalities of each class of medication, rather than each individual
drug
