Final answer:

Opioids decrease neurotransmission by preventing presynaptic Ca2+ influx.


Explanation:

Prior to administering an opioid, patients should be informed that the drug will:

  • Decrease neurotransmission, as these drugs prevent presynaptic Ca2+ influx.

When opioids interact with GABAergic neurons, they cause hyperpolarization and suppress the release of GABA onto dopaminergic VTA neurons, ultimately disinhibiting VTA neurons and increasing dopamine release onto downstream targets.
