10 Questions
Which mechanism of drug action involves the drug serving as a precursor to a neurotransmitter?
Mechanism 1
Which mechanism of drug action inhibits the synthesis of neurotransmitters by inactivating the enzymes responsible for synthesizing precursor chemicals?
Mechanism 2
Which mechanism of drug action prevents the storage of neurotransmitters in synaptic vesicles?
Mechanism 3
Which statement accurately describes the mechanism of action of Narcan?
Narcan inhibits the effects of opioids by blocking the opioid receptors
What happens to the patient immediately after receiving Narcan?
The patient goes into withdrawal due to blocked opioid receptors
How does Narcan differ from drugs that act on postsynaptic receptors?
Narcan does not require presynaptic machinery to take effect
Which mechanism slows down the movement of neurotransmitter-carrying synaptic vesicles towards the membrane?
4
Which mechanism stimulates the autoreceptor to send a stop signal for the release of neurotransmitters?
5
Which mechanism blocks the autoreceptors, preventing them from detecting levels of neurotransmitters in the synaptic cleft?
8
Which mechanism blocks the reuptake of a neurotransmitter, leading to its accumulation in the synaptic cleft?
