THE RADIOIMMUNOASSAY OF TRICYCLIC ANTIDEPRESSANTS

The Radioimmunoassay of Nortriptylene and Other Tricyclic Antidepressants

The tricyclic antidepressant group of drugs are amongst the most widely used medicaments in current clinical practice. They have proved to be extremely useful in the treatment of many different types of depression. There are, however, greater than ten-fold differences between different individual subjects in the rate at which they can degrade the various members of the group into biologically i...

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...

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...

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 ...
