Summary Plasma levels of amitriptyline and nortriptyline were measured twice weekly in 62 patients treated for three weeks with i.m. amitriptyline 120 mg/day. In half the patients the ratio of amitriptyline to nortriptyline was under 1 and in the other half it was greater than 1. 30 of these 62 patients were clinically monitored with the Hamilton Rating Scale and the side effects of the drug were recorded. There was no correlation between plasma level of the drug and its side effects, but there was a statistically significant curvilinear correlation between the plasma levels of amitriptyline plus nortriptyline and nortriptyline alone, and the clinical effect. The practical value of this type of investigation was demonstrated by showing that patients whose drug plasma level was not in the therapeutic range, were clinically improved after adjustment of the dose. The plasma level of amitriptyline plus nortriptyline must lie between 60 to 220 ng/ml, and that of nortriptyline between 60 to 140 ng/ml, to obtain the best clinical effect. Associated treatments, age, weight and sex of patients, and the type of depression did not appear significantly to affect the plasma level of the drug.
