The author has performed an open study of 27 patients with an acute depressive state, hospitalized and treated with slow intravenous perfusions of amitriptyline. Similar perfusions of chlorimipramine act certainly more rapidly on depression, but conversion to oral dose raises some problems regarding active dosis. Intravenous amitriptyline reduces latency, is more sedative and without major intolerance, such as hemodynamic. Conversion to oral diffused forms (Redomex diffucaps) consolidates the results obtained by parenteral administration, and the antianxiety component permits the use of this drug in monotherapy.

The results of a double-blind trial of a tetracyclic antidepressant, maprotiline (Ludiomil) and a conventional tricyclic, amitriptyline (Elavil), in 67 ambulatory depressives are reported. Hamilton's Rating Scale for Depression was the main outcome criterion. No statistically significant differences were found between the drugs in onset of action, efficacy, side effects or predictors of response. Patients on either drug showed a significant reduction in symptoms after 1 week of treatment and at the end of the trial. Both drugs were tolerated well. A review of double-blind comparisons of maprotiline and tricyclic antidepressants, spanning 13 countries, and including over 900 patients, both ambulatory and inpatient, shows essentially similar results. The main outcome criterion in all these studies was manifest psychopathology assessed on the Hamilton Rating Scale for Depression by the treating physician. The absence of additional types of outcome criteria or assessment techniques, which may have detected differences in motor activity or drive as originally postulated, may have obscured results which were expected to be subtle.

The frequency, intensity and profile of adverse effects of antidepressants was studied in elderly patients. The series consisted of 102 patients with depression admitted to hospitals in Bratislava and Moscow. The adverse effects of amitriptyline (Amitriptylin Spofa) and maprotiline (Ludiomil Ciba-Geigy) were compared. The assessment done on days 0, 7, and 28 of treatment showed that xerostomia had the highest occurrence rate with both preparations studied. In patients treated with amitriptyline adverse effects were more severe and were recorded more frequently, requiring treatment withdrawal in 3 patients. The overall intensity of adverse effects was significantly higher with amitriptyline (p < 0.05). In the group of patients treated with amitriptyline the adverse effects were more marked in those with severe somatic pathology. The risk of amitriptyline treatment in elderly patients is being emphasized along with the need for monitoring and correcting adverse effects of the treatment. Although maprotiline exhibited a lower occurrence rate of adverse effects, cardiac functions should be regularly checked in patients with preexisting cardiac pathology. (Tab. 2, Fig. 3, Ref. 6.).

Tricyclic antidepressants, such as amitriptyline (Elavil), and the nontricyclic agent, fluoxetine (Prozac), bind to growth-regulatory intracellular histamine receptors, associated with anti-estrogen binding sites in microsomes and nuclei. The prototype anti-estrogen binding site/intracellular histamine receptor ligand, N,N-diethyl-2-[4-(phenylmethyl)phenoxy]ethanamine HCl, inhibits normal cell proliferation in vitro but stimulates tumor growth in vivo. Because of their structural similarity to N,N-diethyl-2-[4-(phenylmethyl)phenoxy]ethanamine HCl, we carried out studies to determine whether amitriptyline and fluoxetine stimulate tumor growth and/or development in rodents at concentrations relevant to the treatment of human depression (equivalent human dose range, approximately 100-150 mg/day for amitriptyline and approximately 20-80 mg/day for fluoxetine). All experiments were performed blinded. In studies of growth stimulation of transplantable syngeneic tumors, groups of mice were inoculated s.c. with C-3 fibrosarcoma cells or given i.v. or s.c. injections of B16f10 melanoma cells, followed 24 h later by daily i.p. injections of saline, amitriptyline, or fluoxetine. Tumor latency (fibrosarcoma), aggregate tumor weight (s.c. injected melanoma), or time to death from pulmonary metastasis (i.v. injected melanoma) was determined; drug-induced stimulation of DNA synthesis in C-3 fibrosarcoma cells in vitro was correlated with tumor growth acceleration in vivo. In a mammary carcinogenesis model, the effects of chronic saline, amitriptyline, or fluoxetine administration on the rate and frequency of development of mammary tumors in rats fed dimethylbenzanthracene (DMBA) were compared. Eight of 20 amitriptyline- or fluoxetine-treated mice developed fibrosarcoma tumors by day 5, as compared to none of 20 saline controls (P less than 0.002). Similarly, 20 of 21 DMBA-treated rats receiving the antidepressant drugs developed 33 mammary tumors by week 15 as compared to 5 tumors in 4 of 7 DMBA-treated rats receiving saline (P less than 0.001). For both models, tumor latency decreased 30-40% and, in the DMBA model, tumor frequency increased greater than 2-fold in the antidepressant-treated rats as compared to controls. Stimulation of fibrosarcoma growth in vivo correlated with a corresponding bell-shaped drug-induced increase in DNA synthesis in vitro. While the median time to death from pulmonary metastases did not differ among groups given i.v. injections of melanoma cells, a significant (P less than 0.01) stimulation of growth of s.c. injected melanoma was observed in mice receiving the antidepressants.(ABSTRACT TRUNCATED AT 400 WORDS)

As compared to the psychopharmacological profile of amitriptyline hydrochloride the authors analyse the findings of a comparative clinical trial amitriptyline versus Tryptizol regarding their efficacy in neurotic and presenile depression. 170 inpatients divided into four comparative series were investigated. The drugs were administered according to the same scheme in monotherapy for 30 days. The efficiency and tolerance of these drugs were estimated through clinical observations, the recording of the first ameliorated state and the maximum one, psychological check-up by using Hamilton's scale for depressions, paraclinical investigation, recording of side effects, clinical and paraclinical screening for 0-10-20-30 days. The analysis of clinical findings in the investigated series reveals for both drugs their easy administration, tolerance, incidence and low intensity of the side effects. The comparative estimation of the treatment with amitriptyline and Tryptizol in neurotic and presenile depressions attests a similar therapeutic efficiency.

Our study investigated the effects of light therapy on mainly endogenously depressive patients. We applied white fluorescent light of 1500-2000 lux for a length of 4-6 hours daily. For 10 days no antidepressants or sleeping pills were given. We observed a quick and substantial improvement of depressive symptoms within 3 to 5 days. 9 patients showed a very good and 5 patients a good remission of symptoms. This corresponds to an improvement of 65% and is comparable to the effects of antidepressants. The improvement however with light is more rapid and more intensive, the main improvement is to be seen until the 5th day of treatment. No influence was found on vital signs or laboratory values. The rare side-effect was an increase in general drive and activity, which was perceived as agreeable however, and did not take the character of restlessness. Two times an increase of sexual drive was reported. The patients' self-rating concerning vital energy and concentration improved along with the values of the HDRS and CGI as with the quality of sleep. In general patients found light therapy to be agreeable. 1 patient only minimally improved (295.7). No improvement was to be seen in 5 patients (4 x 296.1, 309.1). From our findings we can conclude that light therapy in our patients had the same therapeutic efficacy as tricyclics. In our study the antidepressive effect of light could be maintained with Amitriptylin. Unlike other authors we did not observe a relapse into depression in the responders after ending light therapy.

Amitryptyline (10 mg/kg), desipramine (5 mg/kg), citalopram (10 mg/kg) and viloxazine (10 mg/kg) were administered to rats either acutely (decapitation 1 hr after i.p. injection) or subacutely (by subcutaneous minipump implantation for 18 days followed by decapitation 24 hr after removal). After acute administration there was not any consistent alteration in GABA levels, GAD activity, 3H GABA "A" or 3H-GABA "B" receptor binding or 3H-nipecotic acid binding to the recognition site for GABA uptake in the frontal cortex or hippocampus. Upon subacute antidepressant drug infusion, GABA levels, GAD activity and 3H-GABA-"A" binding showed only scattered differences in drug treated animals as compared to saline treated rats. However, 3H-GABA "B" binding in the frontal cortex was consistently elevated after all drug treatments (in % of control: amitryptyline = 155%; desipramine = 151%; citalopram = 173%; viloxazine = 189%). Scatchard analysis showed that this was due to a Bmax increase without an effect in Kd. These findings were reproduced by subacute administration of pargyline, a MAO inhibitor. These data suggest that GABA "B" receptors may be involved in the mechanism of action of antidepressant drugs and provide a link between GABAergic and monoaminergic hypotheses of depression.

This was a single-blind 4-week parallel group comparative trial in fifty depressed patients. Twenty-five patients received 50 mg of Lentizol, a sustained-release form of amitriptyline, and twenty-five received 75 mg of Prothiaden. Both groups took their drugs as a single night-time dose. Patient response was measured on a symptom check-list which was completed by the doctor and a self-rating depression scale. Tolerance was assessed by recording volunteered and observed side-effects and also by taking the pulse, blood pressure and an electrocardiogram before treatment and after 2 and 4 weeks. A statistically better response was seen with Prothiaden at each follow-up assessment (1, 2 and 4 weeks) compared to Lentizol as measured by both the symptom check-list and the self-rating scale. Less side-effects was also seen with Prothiaden. Minor changes were seen in the ECG records of two patients on Prothiaden and three on Lentizol. These changes were not associated with any clinical change in the patients' cardiovascular state. No consistent changes of any clinical significance were seen in the pulse and blood pressure recordings.

Frequent antihistaminic side effects noted during treatment of depression by tricyclic drugs, as well as the high affinity of tricyclic antidepressants for H1 receptors in mouse neuroblastoma cells, suggest possible useful antihistaminic properties. We investigated the antipruritic activity of topically applied 5% solutions of doxepin hydrochloride (Adapin; Sinequan) and amitriptyline hydrochloride (Elavil) and compared such activity to that of a 5% solution of diphenhydramine and vehicle alone. Test solutions were applied to 25-cm2 areas on the flexor forearms of forty subjects, and the development of itch to single drops of eight dilutions of histamine phosphate instilled in each area was reported over a 3-minute period. The lowest concentration of histamine able to elicit unequivocal itching in each treated area was the histamine itch threshold (HIT). Doxepin, amitriptyline, and diphenhydramine all produced significantly higher mean and median HITs (p less than 0.01 than did vehicle control. Sixty-eight percent of subjects had a HIT greater than or equal to 2 x 10(-4) mg/ml in doxepin-treated areas versus 58% for amitriptyline, 53% for diphenhydramine, and 25% for vehicle. Our data suggest that tricyclic antidepressants are effective topical antipruritic agents.

The frequency of depression-pain association, gives the authors the opportunity of evaluating the actual pattern of managing pain according to its sensory-discriminatory, affective-emotional, cognitive and behavioral features. The neurophysiologic, affective and psychologic factors generally correlate in the induction and evolution of pain, being dependent on the individual reactivity environmental and socio-cultural relations. The efficacy of antidepressive drugs in the therapy of pain, explained by their action on the serotoninergic systems, advocates the clinical relationship depression-pain, but also their analgesic properties independent from the thymoanaleptic effect. The results of the clinical essays the authors have carried on some antidepressants (Imipramine, Amitryptyline, Mianserine, Maprotyline) evidenced their effect on the various forms of manifestation and localizations of pain complains. The amelioration of pain, certified by the use in dynamics of Hamilton's depression scale, occurs earlier than the improvement of depressive symptoms, thus attesting the analgesic properties of the antidepressants. The preservation and merging of these effects during the investigation interval, at the same time with an improvement in the depressive symptoms support the clinical correlation depression-pain, emphasizing the complex character of the algopathic syndrome, both somatically and mentally.
