title: [Compliance, subdosage and overdosage of antidepressive agents in the first prescription in a hospital milieu].
abstract: It is common clinical experience that depressed patients comply poorly with their treatment schedules. In a retrospective study, the authors studied the compliance with the tricyclic antidepressant treatment (TCA) in 1,023 in-patients and evaluated the frequency of the plasma levels under or above the therapeutic range, following a first prescription of TCA. To describe the adherence to the TCA regimen, the investigators have classified patients as either "compliant" or "bad compliant" on the basis of two different arbitrary dividing points: plasma levels of tertiary OR secondary amine lower than 20 ng/ml, or plasma levels of tertiary AND secondary amine lower than 20 ng/ml. The antidepressant plasma levels were measured, on steady state conditions, using a gas chromatographic method. The incidence of bad compliance ranged between about 2.5 and 10%, depending on the criteria used, the incidence of plasma levels under or above the therapeutic window ranged respectively between 26 and 54%-4 and 24%. The results from this study should encourage TCA plasma level measurements.
