<prompt> All are anti-craving agents for alcohol exceptLorazepamNaltrexoneTopiramateAcamprosate  <response>: Anti-craving agentsAcamprosate, naltrexone and SSRIs such as fluoxetine are among the medications tried as anti-craving agents in alcohol dependence. Acamprosate the Ca salt of N-acetyl-homo taurinate interacts with NMDA receptor-mediated glutamatergic neurotransmission in the various brain regions and reduces Ca fluxes through voltage-operatedchannels. Naltrexone oral opioid receptor antagonist probably interferes with alcohol-induced reinforcement by blocking opioid receptors. Fluoxetine and other SSRIs have been occasionally used as anti-craving agents in their usual antidepressant doses.
