Ambroxol inhibits interleukin 1 and tumor necrosis factor production in human mononuclear cells.

We have studied the effect of Ambroxol on the production of Interleukin-1 (IL-1) and Tumor Necrosis Factor (TNF) in human mononuclear cells (MNC). For this purpose MNC were cultured for 24 h in the presence of endotoxin and different doses of Ambroxol. The results indicate that Ambroxol markedly inhibited IL-1 and TNF production at doses of 10-100 microgram ml, without any apparent toxicity.
