What identifies Barbiturates in terms of their names?

Barbiturates are a class of medications that are characterized by their specific naming convention, which includes the suffix "-barbital." This naming convention reflects the chemical structure of these drugs, which are derived from barbituric acid. Common examples of barbiturates that illustrate this naming pattern include phenobarbital and secobarbital. The use of "-barbital" as a suffix clearly distinguishes them from other classes of medications, providing an easy way to identify their category.

The other suffixes mentioned in the question refer to different classes of drugs. For instance, names that end in "-pam" are typically associated with benzodiazepines, which are a separate class of sedatives and anxiolytics. Similarly, "-pram" indicates a class of selective serotonin reuptake inhibitors (SSRIs) used primarily for the treatment of depression and anxiety, while "-cain" is commonly found in local anesthetics. Thus, the suffix "-barbital" is specific to barbiturates and is the correct choice for identifying this class of medications.
