Class

• Neuroscience-based Nomenclature: glutamate multimodal (Glu- MM) Alcohol dependence treatment

Campsate commonly prescribed for

(Bold for FDA approved)

How Campsate works

• Theoretically reduces excitatory glutamate neurotransmission and increases inhibitory gamma-aminobutyric acid (GABA) neurotransmission

• Binds to and blocks certain glutamate receptors, including metabotropic glutamate receptors

• Because withdrawal of alcohol following chronic administration can lead to excessive glutamate activity and deficient GABA activity, acamprosate can act as “artificial alcohol” to mitigate these effects

How long until Campsate works

• Has demonstrated efficacy in trials lasting between 13 and 52 weeks

Notable Side Effects

• Anxiety, depression
