Bupropion is a NDRI. Then you would have to add on an SSRI. However, 2 antidepressants aren’t usually prescribed together.
Edit: dextromethorphan/bupropion (brand name Auvelity). The dextromethorphan hits multiple targets including NMDA and sigma 1, but technically has some inhibition activity to SERT. I am unsure how strong that activity is, whether it is dose dependant, if its an active metabolite etc. Also should point out that nowhere on the manufacturers website do they talk about using the dextromethorphan to hit serotonin. According to the website, the true mechanism of action of Auvelity for treating MDD is not well understood.
Edit2: check out this page. Gives more info and some references. Apparently fairly strong against SERT. [(https://tmedweb.tulane.edu/pharmwiki/doku.php/dextromethorphan)]
Differences: N-acetylcysteine is formulated as both IV or inhalation solutions, whereas the effervescent formulation (brand name Legubeti, FDA approved Feb 2024) is given as an oral solution. According to the prescribing information, Legubeti active ingredient is actually acetylcysteine lysine, but is still dosed based on acetylcysteine. Dosing is technically not an exact conversation (4.74 g of acetylcysteine lysine = 2.5 g acetylcysteine), however, clinically, we are always dosing based on acetylcysteine. It appears to be manufactured in two strengths 500mg and 2.5 g (acetylcysteine content).
Tldr: nac or acetylcysteine lysine —>convert to acetylcysteine. We always dose based on acetylcysteine. The effervescent is specifically formulated for PO administration and indicated for acetaminophen OD.
