Dopamine
In a randomized, placebo-controlled, double-blind trial, the protective effect of low-dose dopamine given as a continuous infusion in cisplatin toxicity was evaluated. No differences were observed in favor of the dopamine group when audiogram results were analyzed at 2,000, 4,000, or 8,000 Hz (P =0.27, 0.14, and 0.49, respectively)(Somlo et al., 1995).
