Moclobemide is a reversible inhibitor of monoamine oxidase-A (MAO-A) with IC50 value of 10μM [1].

Moclobemide is a prototype of RIMA agents. It is found to possess antidepressant efficacy with less risk of fatal side-effects like hypertensive crisis. Moclobemide shows a weak but specific inhibition of MAO-A in the in vitro assay using rat brain homogenates. The IC50 values of MAO-A and MAO-B in the assay are 6mM and 1000mM, respectively. In ex vivo animal experiments, moclobemide produces an inhibition of 80% in the brain and liver. Additionally, the long-term administration of high doses of moclobemide is found to down-regulate β-adrenoceptors and increase the agonist binding affinity of α1-adrenoceptors. Moreover, moclobemide is rapidly and almost completely absorbed after oral administration. The bioavailability of moclobemide is about 50% after a single administration of 100 mg [2].
