Amitriptyline, a tricyclic antidepressant, has been proposed as an antitumoral drug in oxidative therapy. Its pro-apoptotic effects, mediated by high reactive oxygen species generation, have been already described. In this study we analysed the effect of amitriptyline on the biosynthesis of coenzyme Q10 (CoQ), an essential component for electron transport and a potent membrane antioxidant involved in redox signaling. We treated H460 cells, a non-small-cell lung cancer cell line, with amitriptyline and we analyzed CoQ levels by HPLC and CoQ biosynthesis rate, as well as the enzymes involved in CoQ biosynthesis by real-time PCR and Western blot...

PURPOSE OF REVIEW: Chronic pain is usually managed by various pharmacotherapies after exhausting the conservative modalities such as over-the-counter choices. The goal of this review is to investigate current state of opioids and non-opioid medication overuse that includes NSAIDs, skeletal muscle relaxants, antidepressants, membrane stabilization agents, and benzodiazepine. How to minimize medication overuse and achieve better outcome in chronic pain management? RECENT FINDINGS: Although antidepressants and membrane stabilization agents contribute to the crucial components for neuromodulation, opioids were frequently designated as a rescue remedy in chronic pain since adjunct analgesics usually do not provide instantaneous relief...

Purpose The aim of this nationwide, register-based cohort study was to determine whether women treated for depression before primary early-stage breast cancer are at increased risk for receiving treatment that is not in accordance with national guidelines and for poorer survival. Material and Methods We identified 45,325 women with early breast cancer diagnosed in Denmark from 1998 to 2011. Of these, 744 women (2%) had had a previous hospital contact (as an inpatient or outpatient) for depression and another 6,068 (13%) had been treated with antidepressants...

Tamoxifen (Tmf), is a standard of care for women with estrogen receptor positive (ER+) breast cancer. Endoxifen is a Tmf metabolite generated by cytochrome P450 2D6 (CYP2D6). Antidepressive agents (AD) are often prescribed to women with breast cancer not only for depression, but also for anxiety and hot flashes. Some AD are substrates or inhibitors of the Tmf metabolic pathway. Therefore there may be interactions when Tmf and AD are prescribed simultaneously. Oncologic protection afforded by Tmf may become less effective or null when AD are indicated, especially in poor metabolizing patients...

Weak bases that readily penetrate through the lipid bilayer and accumulate inside the acidic organelles are known as lysosomotropic molecules. Many lysosomotropic compounds exhibit therapeutic activity and are commonly used as antidepressant, antipsychotic, antihistamine, or antimalarial agents. Interestingly, studies also have shown increased sensitivity of cancer cells to certain lysosomotropic agents and suggested their mechanism of action as a promising approach for selective destruction of cancer cells...

This study was designed to examine the rapid antidepressant effects of single dose ketamine on suicidal ideation and overall depression level in patients with newly-diagnosed cancer. Forty-two patients were enrolled into the controlled trial and randomized into two groups: ketamine group and midazolam group. Patients from the two groups received a sub-anesthetic dose of racemic ketamine hydrochloride or midazolam. Suicidal ideation score, measured with the Beck Scale and suicidal part of the Montgomery-Asberg Depression Rating Scale, significantly decreased on day 1 and day 3 in ketamine-treated patients when compared to those treated with midazolam...

Selective Serotonin Reuptake Inhibitor antidepressants, such as fluoxetine (Prozac), have been shown to induce cell death in cancer cells, paving the way for their potential use as cancer therapy. These compounds are able to increase cytosolic calcium concentration ([Ca2+]cyt), but the involved mechanisms and their physiological consequences are still not well understood. Here, we show that fluoxetine induces an increase in [Ca2+]cyt by emptying the endoplasmic reticulum (ER) through the translocon, an ER Ca2+ leakage structure...

BACKGROUND: Dementia, with Alzheimer's disease (AD) being the most common form, is a major hip fracture risk factor, but currently it is not known whether the same factors predict hip fracture among persons with and without dementia/AD. We compared the predictors of hip fracture and mortality after hip fracture in persons with and without AD. METHODS: An exposure-matched cohort of all community-dwellers of Finland who received a new clinically verified AD diagnosis in 2005-2011 and had no history of previous hip fracture (N = 67,072) and an age, sex, and region-matched cohort of persons without AD (N = 67,072)...

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most disabling and demoralizing problems that arise for cancer survivors. When investigating symptoms of numbness, tingling, or pain in the extremities, it is critical to determine whether the problem is neuropathic, somatic, or mixed. If the diagnosis is CIPN, it is important to weigh the potential benefits and harms of possible treatment options, and to devise an evidence-based multimodality treatment program. Such programs may include mixtures of opioid and nonopioid adjunctive medications, based on evidence from CIPN trials, and also extrapolation from trials in patients with other neuropathic pain syndromes-although such extrapolating must be done with caution, since other syndromes sometimes respond to agents that CIPN does not respond to...

Tricyclic antidepressants (TCA) have been clinically prescribed in the auxiliary treatment of cancer patients. Although protriptyline, a type of TCA, was used primarily in the clinical treatment of mood disorders in cancer patients, the effect of protriptyline on physiology in human osteosarcoma is unknown. This study examined the effect of protriptyline on cytosolic free Ca(2+ )concentrations ([Ca(2+)]i) and viability in MG63 human osteosarcoma cells. Protriptyline between 50 and 250 μM evoked [Ca(2+)]i rises concentration-dependently...
