Marplan is the trade name for the drug isocarboxazid, one of the hydrazine class of antidepressants, manufactured by Roche, circa 1965. It was stocked in a psychiatric hospital pharmacy in Victoria, Australia. Isocarboxazid is a monoamine oxidase inhibitor (MAOI) and was prescribed for its antidepressant and anxiolytic properties. Due to its strength, significant side-effects and ability to react with some foods, Marplan was considered for patients for whom other antidepressant treatments had failed to have any effect, as a drug of last resort.
