Maprotiline (sold as Deprilept®, Ludiomil®, Psymion®) is a tetracyclic antidepressant. It is a stong norepinephrine reuptake inhibitor with only weak effects on serotonin and dopamine reuptake.
It exerts blocking effects at the following postsynaptic receptors:
- Strong : alpha1
- Moderate : 5-HT2, muscarinic, H1, D2
- Weak : alpha2
- Extremely weak : 5-HT1
The pharmacologic profile of Maprotiline explains its antidepressant, sedative, anxiolytic, sympatholytic, and anticholinergic activities. Additionally, it shows a strong antagonism against Reserpine-induced effects in animal studies, as the other 'cassical' antidepressants do. Although Maprotiline behaves in most regards as a 'first generation antidepressant' it is commonly referred to as 'second generation antidepressant'.
Sedation has a fast onset (the same day), while remission of the depression itself is noted usually after a latent period of 1 to 4 weeks.
Maprotiline does not brighten up the mood in nondepressed persons.
Maprotiline was developed and has been marketed by the Swiss manufacturer Geigy (now Novartis) since the early 1980's under the brand name Ludiomil®. Generics are widely available.

N.B. The use of Maprotiline in the treatment of Enuresia in pediatric patients has so far not been systemetically explored and its use can therefore not be recommended.
