Quetiapine's anticholinergic properties antagonize the pro-cholinergic mechanism of donepezil, potentially impairing cognitive benefits in dementia.

                                Donepezil + Diphenhydramine
                            
                        

                        
                        
Diphenhydramine's potent anticholinergic effect directly opposes donepezil's pro-cholinergic mechanism, negating therapeutic benefit and increasing risk of delirium in elderly patients.
