High performance liquid chromatographic determination of dothiepin and northiaden in human plasma and serum.
Brodie RR, Chasseaud LF, Crampton EL, Hawkins DR, Risdall PC.
A method has been developed for the separation and measurement of dothiepin and the N-demethyl metabolites, northiaden, in human plasma or serum by high performance liquid chromatography. The method uses a structurally-related drug, amitriptyline, as an internal standard and provides a limit of detection of about 10 ng/ml for each component. At a concentration of 20 ng/ml, northiaden and dothiepin could be measured with +/-11% and +/- 6% of the mean respectively and at 200 ng/ml within +/-3% and 1% of the mean. The method has been applied to the analysis of serum from patients undergoing dothiepin therapy.

High-performance liquid chromatographic determination of perphenazine and amitriptyline hydrochloride in two-component tablet formulations.
Butterfield AG, Sears RW.
A rapid, precise, and accurate high-performance liquid chromatographic procedure is presented for the simultaneous determination of perphenazine and amitriptyline hydrochloride in two-component tablet formulations. An aliquot of a methanolic extract of the tablet, containing trifluoperazine hydrochloride as an internal standard, is chromatographed on a nitrile bonded phase microparticulate column using a 0.005 M ammonium acetate-methanol (20:80) mobile phase. Quantitation is by peak area. The relative standard deviations for the procedure are 0.34 and 0.54% for the simultaneous determination of perphenazine and amitriptyline, respectively. Eight commercial tablet formulations were analyzed and found to contain 96.5-101.5 and 96.5-103.3% of the labeled amounts of perphenazine and amitriptyline hydrochloride, respectively.
