Drug name suffixes, known as stems in International Nonproprietary Names, are systematically used by regulatory programs to indicate pharmaceutical classes and pharmacological interrelationships.
The retrieved papers, specifically those discussing International Nonproprietary Names (INNs) and pharmaceutical nomenclature (such as papers [2] and [4]), explicitly state that drug names utilize common stems or suffixes to represent pharmaceutical classes and indicate pharmacological interrelationships. There is no contradictory evidence regarding this naming convention.
