Phenytoin
A hydantoin anticonvulsant, in use since 1938 against epileptic seizures: unlike the medicines of the time, it controlled seizures without strong sedation. This family brings together the active ingredient, pharmacopoeial impurities, labelled standards and other impurities.
Did you know?First synthesised in 1908 by German chemist Heinrich Biltz, it sat in a drawer for almost thirty years until Merritt and Putnam, searching for non-sedating relatives of phenobarbital, discovered its anti-seizure effect.
