Amitriptyline, a tricyclic antidepressant, is commonly used to treat depression and neuropathic pain, but its mechanism is still unclear. We tested the effect of amitriptyline on 5-hydroxytryptamine 3 (5-HT₃) receptor currents and studied its blocking mechanism because the clinical applications of amitriptyline overlapped with 5-HT₃ receptor therapeutic potentials. Using a whole-cell voltage clamp method, we recorded the currents of the 5-HT₃ receptor when 5-HT was applied alone or co-applied with amitriptyline in cultured NCB-20 neuroblastoma cells known to express 5-HT₃ receptors. To elucidate the mechanism of amitriptyline, we simulated the 5-HT₃ receptor currents using Berkeley Madonna® software and calculated the rate constants of the agonist binding and receptor transition steps. The 5-HT₃ receptor currents were inhibited by amitriptyline in a concentration-dependent, voltage-independent manner, and a competitive mode. Amitriptyline accelerated the desensitization of the 5-HT₃ receptor. When amitriptyline was applied before 5-HT treatment, the currents rose slowly until the end of 5-HT treatment. When amitriptyline was co-applied with 5-HT, currents rose and decayed rapidly. Peak current amplitudes were decreased in both applications. All macroscopic currents recorded in whole cell voltage clamping experiments were reproduced by simulation and the changes of rate constants by amitriptyline were correlated with macroscopic current recording data. These results suggest that amitriptyline blocks the 5-HT₃ receptor by close and open state blocking mechanisms, in a competitive manner. We could expand an understanding of pharmacological mechanisms of amitriptyline related to the modulation of a 5-HT₃ receptor, a potential target of neurologic and psychiatric diseases through this study.

Tricyclic antidepressant (TCA) is a useful drug for treating neuropathic pain. However, tremors are one of the relatively frequent side effects of TCA. A female patient, who was suffering from postherpetic neuralgia, was treated with amitriptyline starting with 10 mg/day. She developed resting tremors on the second day after increasing the dose to 30 mg/day. This case highlights the need for the careful use of amitriptyline in the treatment of neuropathic pain in elderly patients.

BACKGROUND: Current therapy for the treatment of neuropathic pain is often unsatisfactory. Considerable variation in treatment pattern still exists in spite of availability of sufficient literature from various guidelines. Recent Indian market data suggested that the utilization (sale) of drugs such as amitriptyline, pregabalin, and gabapentin was more for low-dose unit packs than that of the high-dose unit packs, raising the belief that these drugs are prescribed at a lower dose than is actually recommended in the guidelines. To test this hypothesis, a survey was conducted across speciality throughout the country to observe the prescription pattern of these drugs amongst the health care providers in India. METHODS: Three hundred fifty survey forms were distributed of which 281 forms were included for analysis. RESULTS: It was observed that the commonly used initiation and maintenance dose for amitriptyline, pregabalin, and gabapentin was 5–10 mg/day, 50–75 mg/day, and 100–300 mg/day, respectively. The reason to select the lower dosages was to have a balancing effect to achieve good efficacy with minimum side effects. Care-givers reported no side effects/not many side effects as a reason in 22.2%, 16.88%, and 23.86% patients with amitriptyline, pregabalin, and gabapentin, respectively. Sedation and giddiness were commonly reported with all three drugs. CONCLUSIONS: Commonly prescribed drugs for management of neuropathic pain, such as amitriptyline, pregabalin, and gabapentin are preferred at lower doses in Indian clinical settings. Acceptable efficacy and low tolerance to the standard dosage is believed to be the reason behind the prescribed dose.

Prospective clinical trial on two groups of patients: one treated with amitryptyline and the other with diantalvic. Results: At the beginning of study, no difference in the severity of pain in both groups. Group 1 had more effective to control pain than group 2. After one week of treatment, group 1 had one case (3.3%) while group 2 had 15 cases (35.7%) didn’t have any improvement. Amitriptyline had more advantages that Diantalvic to treat the postzosterian pain

PURPOSE: To report the clinical experience with amitriptyline for managing children with cyclic vomiting syndrome (CVS). METHODS: Totally, eleven children (eight males) were diagnosed with CVS. Of these, medical records were reviewed for eight children treated with amitriptyline; three children were not treated because one was not followed up and two were kept under observation to study the natural course without medication, because the frequency of vomiting had recently decreased to less than one episode per year. The eight amitriptyline-treated children were divided into three groups by the therapeutic response: (1) complete remission (CR), with no recurrence of symptoms after treatment; 2) partial remission (PR), in which the frequency of symptoms decreased by almost 50% after treatment; and (3) no response. RESULTS: For the eight amitriptyline-treated children, the mean age of symptom onset was 4.7 (0.3-7) yr and mean age at diagnosis was 8.9 (6.0-11.3) yr. The mean number of vomiting episodes was 8.8 (2-25) per year, and the duration of vomiting in each episode ranged from 3 hours to 5 days. CR was achieved in five (62.5%) of the eight amitriptyline-treated children (0.2-0.8 mg/kg/day orally, at night) and PR was achieved in three children (37.5%). Two children relapsed on discontinuation of amitriptyline by their parents decision but showed improvement on remedication. No adverse effects were noted throughout the study period. CONCLUSION: Amitriptyline can be used in long-term prophylaxis for the management of children with CVS aged over 6 yr. However, a large-scale study is needed to ascertain its effects.

OBJECTIVE: The purpose of this study was to compare the plasma amitriptyline and nortriptyline level between before and after fluoxetine addition with patients who were currently taking amitriptyline. METHOD: From the inpatient and outpatient unit of Soon Chun Hyang University Hospital, Chunan, fourteen subjects who were taking amitriptyline 25mg more than 1 week at least were given fluoxetine 20mg. Before and 2 weeks after fluoxetine addition the plasma level of amitriptyline and nortriptyline are analyzed simultaneously by High Performance Liquid Chromatography(HPLC) At the same times, HAM-D(Hamilton Rating Scale for Depression) score and the UKU(Uldvalg for Klinske Unders phi gelser) side effect scale were checked. RESULTS: After fluoxetine addition to the patients who were taking amitriptyline, the plasma level of amitriptyline, nortriptyline and sum of amitriptyline and nortriptyline had risen. The mean plasma amitriptyline level increased from 168.9+/-89.4ng/ml to 183.0+/-102.0ng/ml after fluoxetine addition(p=0.011) but the change was not statistically significant. The mean plasma nortriptyline level increased significantly from 114.3+/-70.2ng/ml to 168.0+/-86.2ng/ml after fluoxetine addition(p=0.011) In addition, the mean plasma level of total amitriptyline and nortriptyline increased significantly from 283.1+/-125.3ng/ml to 350.9+/-78.4ng/ml after fluoxetine addition(p=0.016) After fluoxetine addition, no significant change was noted in the UKU side effect scale score. CONCLUSION: As consequence of comparson of plasma amitriptyline and nortriptyline level before and after fluoxetine addition mean amitriptyline, nortriptyline and total plasma level was increased after fluoxetine addition. This suggests that coadministration of amitriptyline and fluoxetine may induce improvement of depressive symptom in depressive patients by way of increased plasma level of amitriptyline.
