I take it first thing in the morning, once daily, at a dose of 12.5 mg (a quarter of a 50 mg tablet).
Some of amisulpride's drug interactions are listed here
There is a drug interactions checker here
that recognizes amisulpride.
There is a major drug interaction between risperidone
(another atypical anti-psychotic) and bupropion. But could not find any interaction between bupropion and amisulpride.
Note also that 12.5 mg daily is a very low dose amisulpride protocol. The maximum dose of amisulpride is 1200 mg, so any interactions at 12.5 mg daily will likely be a lot less significant than at the max dose.
