KK: /nɑnˈbɑrbɪtʃərɪt/
A substance that does not belong to the group of drugs known as barbiturates, which are used to treat anxiety and sleep disorders.
Doctors may prescribe a nonbarbiturate for patients who need help sleeping without the risks associated with barbiturates.
Nonbarbiturate → It is formed from "non-" (meaning not) and "barbiturate" (from the chemical name for a class of drugs derived from barbituric acid). The word refers to substances that are not barbiturates, which are a type of sedative or sleep-inducing medication.
Think of 'non-' meaning 'not' to remember that 'nonbarbiturate' refers to something that is not a barbiturate.
