A monoamine releasing agent, or simply monoamine releaser, is a drug that induces the release of one or more monoamine neurotransmitters from the presynaptic neuron into the synapse, leading to an increase in the extracellular concentrations of the neurotransmitters and hence enhanced signaling by those neurotransmitters.

A serotonin releasing agent is a type of drug that induces the release of serotonin into the neuronal synaptic cleft.

A dopamine releasing agent is a type of drug which induces the release of dopamine in the body and/or brain.
