alert. Most drugs act in one of the following ways. Agonists are drugs that mimic neurotransmitters and cause neurons to fire. Antagonists are a second type of drug. These attach to receptor sites on a neuron to stop its ability to fire. Finally‚ a third type of drug is a reuptake inhibitor. These drugs work by attaching to axon branches so that the axon terminal cannot suck up the leftover neurotransmitter in the synapse‚ thus creating an excess of the
