  • Title: Dopamine metabolism and neurotransmission in primate brain in relationship to monoamine oxidase A and B inhibition.
    Author: Youdim MB, Riederer P.
    Journal: J Neural Transm Gen Sect; 1993; 91(2-3):181-95. PubMed ID: 8390270.
    Abstract:
    The "cheese effect", potentiation of sympathomimetic action of indirectly acting amines such as tyramine, the main side effect of irreversible non-selective and selective monoamine oxidase (MAO) A inhibitors, has largely been eliminated in the new generation of reversible selective MAO-A and B and irreversible MAO-B inhibitors. These selective inhibitors are demonstrating unique pharmacology and initial controlled clinical studies are providing evidence to support their action as anti-depressants and anti-Parkinson's disease drugs and possibly as neuroprotectors. Thirty years of experience with non-selective MAO inhibitors has resulted in a better understanding and management of the new generation of MAO inhibitors. Because of their selective action on the specific forms of MAO, which results in selective elevation of brain noradrenaline and serotonin on the one hand and dopamine and phenylethylamine on the other, it is hoped that these drugs will be able to elucidate the functional roles of MAO-A and B subtypes with regards to dopamine metabolism in the human brain.
