Neurosteroids in nicotine and morphine dependence.

abstract：:The problem of the advantage of using nortriptyline (NT) plasma level during treatment for endogenous depression has been approached. In an ordinary psychiatric department, 34 patients had their NT level checked the second week of treatment and their dosage subsequently adjusted, if it was outside the recommended ther...
