Abstract
• Eleven McLean Hospital (Belmont, Mass) depressed patients who experienced seizures while receiving maprotiline hydrochloride are presented, as are data on 87 cases reported to the manufacturer (Ciba-Geigy). Most seizures occurred at high dosages, sometimes after many weeks at a stable dose, but neither rapid dosage escalation nor high drug plasma levels seemed related to seizure occurrence. Our experience suggests that a long-acting metabolite might be responsible for seizures. Ten of the 11 McLean Hospital seizures occurred in patients receiving dosages outside of the since-revised current dosage guidelines, as did 60% of the seizures reported to the company. Data in this study suggest that reductions in maximum dosage of maprotiline prescribed after the initial six weeks of treatment could result in a further decrease in risk of seizures beyond that obtained from previous alterations in regimens.
