Inhibitory effects of amantadine on the production of pro-inflammatory cytokines by stimulated in vitro human blood.
Journal Title: Pharmacological Reports - Year 2009, Vol 61, Issue 6
Abstract
Treatment with amantadine (AMA), an N-methyl-D-aspartate (NMDA) receptor antagonist and antidepressant drug, increased the antidepressant activity of subsequent drugs in experimental studies and in patients suffering from treatment-resistant depression (TRD). Recent evidence indicates that depression may be accompanied by activation of an inflammatory response. These data indicate that pro-inflammatory cytokines may play a role in the etiology of depression, particularly in TRD. The present in vitro study shows the ability of AMA, used at concentrations between 10(-7) to 10(-5) M, to reduce the production of the pro-inflammatory cytokines, specifically interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha). In addition, AMA treatment increased the production of the negative immunoregulator, interleukin-10 (IL-10). Furthermore, the combined treatment of AMA with fluoxetine (FLU), but not imipramine (IMI), had a stronger immunomodulatory effect on cytokine production than AMA alone. The above data provide additional rationale for the treatment of patients suffering from depression with a combination of AMA and a selective serotonin reuptake inhibitor.

Bradykinin receptor antagonists and cyclooxygenase inhibitors in vincristine- and streptozotocin-induced hyperalgesia.
Pain that accompanies neuropathy is difficult to treat. Analgesics administered as monotherapies possess low activities in relieving this kind of pain. The effect of the simultaneous administration of indomethacin (a pre...
Exendin-4 reduces glycemia by increasing liver glucokinase activity: an insulin independent effect.
Exendin-4 is a stable peptide agonist of GLP-1 receptor that exhibits insulinotropic actions. Some in vivo studies indicated insulin-independent glucoregulatory actions of exendin-4. That finding prompted us to evaluate...
Serum kynurenic acid positively correlates with cardiovascular disease risk factor, homocysteine: a study in stroke patients.
KYNA, an antagonist of ionotropic glutamate receptors and alpha7 nicotinic receptors, has been found as well in the brain as in the periphery. The altered metabolism of KYNA, especially its deficiency, can lead to the en...
Effect of prenatal manganese intoxication on [(3)H]glucose uptake in the brain of rats lesioned as neonates with 6-hydroxydopamine.
In the present study we examined the effects of prenatal manganese (Mn) intoxication on [(3)H]glucose uptake in the brain of rats lesioned as neonates with 6-hydroxydopamine (6-OHDA). MnCl(2) . 4H(2)O (10,000 ppm) was ad...
Effect of ABCB1 (MDR1) 3435C >T and 2677G >A,T polymorphisms and P-glycoprotein inhibitors on salivary digoxin secretion in congestive heart failure patients.
The aim of the present study was to evaluate the effects of ABCB1 (MDR1) gene polymorphism on P-glycoprotein model substrate, i.e. digoxin, salivary secretion. The study was carried out in 77 patients diagnosed with cong...
