Tricyclic antidepressants.

Correspondence BRiTISH 301 Tricyclic Antidepressants SIR,-I am worried by one sentence in the article on tricyclic antidepressants (13 April, p. 102): "Jaundice, which is very uncommon , is of the cholestatic type similar to that found in chlorpromazine." This is misleading. Jaundice is one of the more frequent side-effects reported from imipramine and imitrip-tyline, the most widely used membe...

A radioimmunoassay for nortriptyline (and other tricyclic antidepressants) in plasma.

The radioimmunoassay for nortriptyline described here can detect as little 1 microgram/liter of plasma. Within-day precision and day-to-day precision (CV) were +/- 6 and +/- 11%, respectively, over the concentration range 100-200 microgram/liter. The major metabolite hydroxy-nortriptyline, does not cross react with the antiserum. Results so obtained correlate closely with results by a double-is...

Pharmacokinetics of Tricyclic Antidepressants

This review, together with Part 1 (Gun. Chem. 26: 5-17, 1980), summarizes progress in measurement of tricyclic antidepressants in biological fluids and the application of the methodology to Clinical practice. For many of the older drugs and for all of the new-generation antidepressants, further studies are required to delineate the precise relationship between plasma concentration and clinical ...

Therapeutic monitoring of tricyclic antidepressants in plasma by gas chromatography.

We describe a comprehensive gas chromatographic analysis for therapeutic concentrations of amitriptyline, nortriptyline, imipramine, desipramine, doxepin, and desmethyldoxepin in plasma, with use of a nitrogen detector. All these drugs are extracted and chromatographed under identical conditions. Each tertiary amine tricyclic is well resolved from its secondary amine metabolite on a mixed-phase...
