Patent number: 7989658Abstract: The present invention relates to a process for the purification of gabapentin. The process relates to the addition of hydrochloric acid to an aqueous solution or suspension of gabapentin, before, during or after the concentration step of that solution, and the subsequent slurry of the gabapentin by the addition of an alcoholic solvent. The so obtained gabapentin has an high purity degree and, in particular, is characterized by a low content of lactam.Type: GrantFiled: December 15, 2005Date of Patent: August 2, 2011Assignee: ZaCh System S.p.A.Inventors: Roberto Giovanetti, Andrea Nicoli, Livius Cotarca
