Baklofen (Kemstro, Lioresal, Liofen, Gablofen, i Beklo) je derivat gama-aminobuterne kiseline (GABA). On se prvenstveno koristi za tretiranje spasticiteta. On je u ranom stadijumu istraživanja za moguću upotrebu u tretmanu alkoholizma.

Baklofen je agonist GABA_B receptora.^[6]^[7] Njegovo korisno dejstvo na spasticitet je rezult uticaja na kičmene i supraspinalne lokacije. Baklofen se takođe može koristiti za tretiranje štucanja. Pokazano je da prečava porast telesne temperature indukovane lekom MDMA kod pacova.^[8]

Istraživanja su pokazala da je baklofen efektivan u tretmanu alkoholne zavisnosti i povlačenja, putem inhibicije simptoma povlačenja i žudnje.^[9]

Korisno svojstvo bajlofena je da se tolerancija ne javlja u znatnoj meri — baklofen zadržava svoje terapeutske antispazmodičke efekte čak i nakon nekoliko godina stalne upotrebe.^[10] Međutim, tolerancija se može razviti kod nekih pacijenata koji primaju lek intratekalo.^[11]^[12]^[13]
