The pharmacology of reversible monoamine oxidase inhibitors.

The older monoamine oxidase inhibitors (MAOIs) are mechanism-based, irreversible inhibitors of MAO; most inhibit both the A and B forms of MAO. Several of the drugs are hydrazine derivatives which have non-specific effects other than MAO inhibition. These properties convey disadvantages, which may be seen as serious, though infrequent, adverse events--the 'cheese effect', hepatotoxicity, amphetamine-like activity, orthostatic hypotension and anticholinergic effects. New, reversible MAOIs stem from a variety of chemical classes and are more specific in their effects, with relatively rapid onset of action, direct relationship between plasma concentration and pharmacological effect, and no prolonged carry-over phenomena.

Antidepressant drug therapy: associated risks.

Aspects of risks associated with treatment with three classes of antidepressants: tricyclic (TCA), second generation ("new") antidepressants and monoamine oxidase inhibitor (MAOI), are discussed. Moclobemide, a benzamide derivative, is a new MAOI antidepressant with reversible and preferential inhibition of the A-form of monoamine oxidase. Moclobemide is free of liver toxicity and the risk of a pressor response with tyramine-containing food is so low that strict diet restrictions are unnecessary. That MAOIs have a low incidence of side effects, particularly so called anticholinergic side effects is also true for moclobemide. A serious risk with antidepressant drugs is that the patient will use them to attempt suicide. Therefore important aspects of antidepressants are that they should take effect rapidly and be safe in overdose. No deaths from overdose have been observed with toloxatone, the only reversible MAOI antidepressant on the market to date. It is concluded that the new reversible MAOI antidepressant moclobemide is similar to other antidepressants in terms of efficacy but very noticeably superior in terms of tolerance and safety.
