Cholinergic systemSecondary acetylcholine enhancement
Glutamatergic circuitsDownstream modulation; possible interaction with memantine
Behavioural / mood circuitsSerotonergic modulation
checking Intepirdine and Masupirdine: no hard conflicts (1 to watch), but the amber pairs carry interactions to be careful with.
both are strongly serotonergic; combining them raises total serotonin load and the risk of serotonin syndrome, so this needs real care.
