Galantamine adverse effects

An in vitro study in rats suggested that memantine does not attenuate the anticholinesterase effects of galantamine at therapeutic concentrations. A study in 15 healthy subjects found that the concurrent use of extended-re-lease galantamine 16 mg daily with memantine 10 mg twice daily for 12 days did not affect the pharmacokinetics of galantamine and generally did not increase the incidence of adverse effects, although dizziness may have been more common. ... 

Fluvoxamine markedly increases the levels of tacrine, and increases its cholinei ic adverse effects, whereas fluoxetine, paroxetine, and sertraline are not expected to interact. Paroxetine and fluoxetine may increase donepezil and galantamine levels. Sertraline does not appear to have a pharmacokinetic interaction with donepezil, and concurrent use seems generally well tolerated however, one report describes hepatotoxicity, possibly as a result of their concurrent use. Rivastigmine and fluoxetine appear not to interact.
