Which of the following best describes the action of Narcan on opioid receptors?
Narcan inhibits the effects of opioid medication

The patient experiences withdrawal symptoms
Why are drug mechanisms that act on postsynaptic receptors powerful?
They take the place of neurotransmitters
Which mechanism slows down the movement of neurotransmitter-carrying synaptic vesicles towards the membrane?
