Abstract
A pharmacokinetic study of amineptine (Survector) and its C5 metabolite, resulting from a beta-oxidation of the heptanoic acid side-chain, was undertaken with ten human volunteers, who received a single 100-mg tablet of amineptine orally. They were affected with liver impairment in order to determine if this situation would alter greatly the pharmacokinetic parameters. The internal standard was the octanoic acid homologue. Analyses were carried out by gas chromatography (GC) and GC-mass spectrometry using TMS ester derivatives. Plasma samples were extracted using a C18 reversed-phase cartridge at pH 4.0. Mass fragmentographic measurements on the plasma samples were performed on the m/z ions (M + H)+ and (base peak)+ using ammonia chemical ionization. The global evaluation of precision was good and the coherence between the two modes of measurements, (base peak)+ and (M + H)+ ions, gave a regression factor r close to unity. For amineptine the total body clearance and mean residence time were accurate and precise with eight volunteers, but only four volunteers showed such coherent data for the slope of the elimination curve, beta, and half-life. However, the beta value, half-life and mean residence time of the C5 metabolite were accurate and precise with seven, eight and ten volunteers, respectively. It is concluded that the drug was still detoxified at normal levels.

Abstract
Two deaths due to amitriptyline and desipramine overdoses are reported. The first case deals with a 20-year-old Caucasian male who was found dead at his residence. Toxicological analysis of the blood, urine, liver and kidney revealed the presence of amitriptyline (1.7 mg/l, 0.13 mg/l, 36.0 mg/kg and 98.0 mg/kg) and nortriptyline (0.66 mg/l, 0.74 mg/l, 12.0 mg/kg and 37.0 mg/kg). The gastric content contained only 220 mg of amitriptyline. The urine also contained norverapamil, which was consistent with previous verapamil therapy. The second case involved a 19-year-old Caucasian male who attempted suicide earlier and was on desipramine medication. The blood, urine, liver and gastric content disclosed the presence of desipramine in the concentrations of 14.2 mg/l, 33.7 mg/l, 112.5 mg/kg and 180 mg, respectively. The levels of these tricyclics analyzed by high pressure liquid chromatography were in agreement with the levels reported in the literature. Though with the amitriptyline poisoning no significant anatomic changes were noted, the desipramine-caused death was further supported by the multisystem vascular congestion and ischemic changes consistent with cardiopulmonary failure.

Abstract
The urinary excretion of amitriptyline (AMT) and seven of its metabolites was studied by mass spectrometry in 10 depressive in-patients treated to steady-state condition with oral amitriptyline. An average of 68.3% of the dose was recovered in the urine, of which 68.6% was present as conjugates. Hydroxynortriptyline and its conjugate represented 54% of the total recovery. There was marked variation in metabolite pattern between patients. The variations were not due to concomitant medication with benzodiazepines. There was no correlation between the plasma and urine concentrations of AMT and its metabolites, except for amitriptyline conjugates. Two groups of patients could be distinguished - low and high excretors, who displayed alternative routes of metabolism. The disappearance rate of AMT from plasma was determined by the metabolic clearance of AMT to its metabolites. It varied considerably between patients.

Abstract
A method for the determination of amitriptyline-N-oxide, amitriptyline and nortriptyline in serum and plasma has been developed. After extraction from serum or plasma the drugs were analysed by high-performance liquid chromatography. The detection limit was 10 ng/ml (2 ml serum or plasma actually used). The coefficient of variation for all three compounds was below 10%. Amitriptyline-N-oxide was found in rat plasma after an oral dose (10 mg/kg) of amitriptyline-N-oxide.

Abstract
For the development of radioimmunoassay procedures for tricyclic antidepressants, two drug haptens were synthesized for each of the two amitriptyline--nortriptyline and imipramine--desipramine groups. In one case, nortriptyline or desipramine was treated with succinic anhydride to yield N-(3-carboxypropionyl) derivatives; in the other case, the haptens were novel N-(2-carboxyethyl) derivatives. The hapten and its corresponding ester were characterized by GLC--mass spectrometry, PMR spectrometry, and IR spectrophotometry. Each hapten was coupled to bovine serum albumin, and the number of hapten residues per mole of bovine serum albumin was determined by UV spectrophotometric methods. Antibodies to each hapten--protein conjugate were developed in rabbits, and titers of the antiserums were checked by evaluating their binding characteristics to tritiated drug.

Abstract
A combined thin-layer and gas-liquid chromatographic (TLC-GLC) procedure for determination of tricyclic antidepressant drugs in urine is described. GLC on 1.5% OV-17 was utilized to analyzed basic urine extracts directly for the tricyclics and to confirm the identity of spots extracted from thin-layer chromatograms, and TLC was used to confirm the results of these GLC screens. Lower limits of sensitivity for the thin-layer spot extraction procedure were found to range from 2 mug/ml for amitriptyline and imipramine to 10 mug/ml for desipramine and nortriptyline. Turn-around-times for the GLC tricyclic screens were usually less than 1 h. The finding that nortriptyline and desipramine were chemically altered under various extraction conditions was used as a means of confirming the identity of these drugs, and the identity of these chemically altered derivatives was discussed with reference to their low resolution mass spectra.

Abstract
The kinetics of nortriptyline in four patients were investigated before and during treatment with perphenazine (24-36 mg/day) by administering 57 mg nortriptyline hydrochloride as an intravenous infusion and evaluating the resulting plasma concentration data according to a two compartment open model. In all patients an increased biological half-life as well as a decreased systemic clearance and rate of metabolism were found in the perphenazine-period, thus confirming the inhibitory effect of perphenazine on the metabolism of nortriptyline found in earlier studies. Some interaction with distribution parameters was also indicated, but on the whole the model parameters did not provide much further information about the interaction. Although the most pronounced changes were found with the patient getting the highest dose of perphenazine, the dose-effect relationship remains obscure.

Abstract
A gas chromatographic mass spectrometric method for the quantitative determination of imipramine and its N-demethylated metabolite desipramine in plasma samples at the nanogram level is reported. The method involves derivatization of the extracted drugs with trifluoroacetylimidazole, a mild derivatizing reagent. Specificity is provided by selected ion recording of the [M + H]+ ions, formed upon chemical ionization with methane as reagent gas. Quantitation is achieved by stable isotope dilution techniques, using deuterium labeled analogs, prepared by acid-catalyzed exchange, as internal standards. Data on patient samples are presented.

Abstract
A sensitive and specific method for the simultaneous determination of imipramine and desipramine in the blood plasma of depressed patients under treatment that involves separation by gas chromatography and detection by mass fragmentography is described. Concentrations were determined by focusing the mass spectrometer upon the ions at m/e 280 and 235 for imipramine and 308, 236 and 114 for desipramine (N-acetyl derivative), while promazine was used as the internal standard (ions at m/e 284 and 238). Determinations are possible at levels as low as 10 ng/ml in plasma.

Abstract
Plasma concentrations of nortriptyline have been assayed in four subjects after intravenous infusion of 57 mg nortriptyline hydrochloride. The data were evaluated according to a two compartment open model. The calculated best-fitting curves were in good agreement with the experimental data, better than could be expected from a simpler model. This justifies the assumption that the kinetics of nortriptyline in man may be described by this model with an appropriate input function. The data permitted estimation of all the parameters of the model. The meaning of the parameters is discussed, particularly in relation to individual variation.

Abstract
Variability in the response to drugs is due to three principal components-the disease, the responsiveness of tissues, and the concentration of the drug at its site of action (as reflected by its plasma concentration). The relative contributions of these components will differ not only for different drugs but also for different effects of the same drug. Rational drug therapy depends on knowledge of all three factors.
