    The correct answer is "antagonist".

    A neurotransmitter is a chemical substance of the human body responsible for neurotransmission. Once released from the presynaptic neuron, they bind to specialized receptors located on the postsynaptic neuron. This binding triggers a specific response at the receiving cell.

    An antagonist drug reduces the effects of a neurotransmitter by binding to the specific receptor and preventing the binding of the neurotransmitter.
