Additionally, MAO-B remains free and continues to metabolize tyramine in the stomach, although this is less significant than the liver action. MOA stands for Mechanism of Action, which is the biochemical and physiological process through which a drug or the device produces its effect. Quizlet Learn. As a µ-opioid receptor agonist, the drug can reproduce precisely the natural effects of the opioids, enkephalins, and endorphins in the body, by releasing neurotransmitters that are responsible for pain transmission. Drug MoA is Complicated as It Sounds . The dose of the medicine is gradually tapered until the patient achieves a drug-free state. [47] Agents that act on serotonin if taken with another serotonin-enhancing agent may result in a potentially fatal interaction called serotonin syndrome or with irreversible and unselective inhibitors (such as older MAOIs), of MAO a hypertensive crisis as a result of tyramine food interactions is particularly problematic with older MAOIs. These characteristics can increase the risk of an overdose or respiratory depression when titrating or initiating the therapy.
