From: Effects of guaifenesin, N-acetylcysteine, and ambroxol on MUC5AC and mucociliary transport in primary differentiated human tracheal-bronchial cells

Figure 2

Antioxidant capacity of guaifenesin (GGE), N -acetylcysteine (NAC) and ambroxol (Amb). The ability of the three mucoactive agents to scavenge the free radical/colorimetric indicator as a function of concentration was compared with Trolox (a water soluble vitamin E analogue). NAC was approximately twice as effective (slope -0.316) as Trolox (slope -0.155), but the effects of GGE and Amb were minimal (slopes of 0.032 and 0.025, respectively).
