State

An agonist is a substance that increases a neurotransmitter's activity, by mimicking it or by amplifying its effect.

Show

A drug that blocks serotonin reuptake leaves more serotonin in the synapse and acts as a serotonin agonist.

Watch for

An agonist does not always imitate the transmitter. Blocking its removal produces the same directional result.
