Primidone is an anticonvulsant of the barbiturate class; [7] however, its long-term effect in raising the seizure threshold is likely due to its active metabolite, phenobarbital. [10] The drug’s other active metabolite is phenylethylmalonamide (PEMA). Primidone was approved for medical use in the United States in 1954. [7]
[4] [5] [6] However, barbiturates are still used as anticonvulsants (e.g., phenobarbital and primidone) and general anesthetics (e.g., sodium thiopental). Barbiturates in high doses are used for medical aid in dying , and in combination with a muscle relaxant for euthanasia and for capital punishment by lethal injection .
Treatment can be problematic: Barbiturates and primidone must be avoided as they commonly precipitate symptoms. [28] Some benzodiazepines are safe, and, when used in conjunction with newer anti-seizure medications such as gabapentin, offer a possible regimen for seizure control. [citation needed]
Barbiturates have special uses and are organized into 4 classes: ultrashort-, short-, intermediate- and long-acting. Empirically SARs of barbiturants are based on thousands of (animal) tested compounds. They have shown that R and R´ may not be H in position 5 (see figure 8). Also, position 5 confer sedative-hypnotic properties. [14]

Alphenal, also known as 5-allyl-5-phenylbarbituric acid, is a barbiturate derivative developed in the 1920s. [1] It has primarily anticonvulsant properties and was used occasionally for the treatment of epilepsy or convulsions , although not as commonly as better known barbiturates such as phenobarbital .
