Summary
Cocaine blocks reuptake of catecholamines and serotonin, and with an MAOI it may cause severe hypertension, arrhythmias or serotonin toxicity. Topical medical use gives lower exposure but still carries risk.
What this interaction means in plain words
Cocaine and Isocarboxazid are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Cocaine belongs to Central Nervous System; Isocarboxazid belongs to Central Nervous System.
Why it happens
Monoamine reuptake inhibition combined with inhibited monoamine metabolism increases synaptic catecholamines and serotonin.
What to do
Avoid cocaine in patients on MAOIs, including topical anesthetic use; choose a different local anesthetic.
