Background: Paraquat (PQ) poisoning is characterized by rapidly progressive acute poisoning with high mortality and no specific antidote. Although some clin. studies have been conducted to investigate the benefits of high-dose ambroxol as an adjuvant treatment for PQ poisoning, the efficacy is controversial. Materials and Methods: After searching for relevant articles in English and Chinese databases from 1978 to 2019 according to the keywords (paraquat poisoning/methy viologen/gramoxone, and ambroxol/mucosolvan/Bromhexine), we found seven articles that met our inclusion and exclusion criteria. A meta-anal. was performed using fixed-effects model and random-effects model according to the I2 value in Stata software (version 15.0). Four outcome indicators (hospital mortality, partial pressure of oxygen (PaO2), oxygenation index (PaO2/FiO2), and survival time of the deceased patients) were of interest to us. Results: The meta-anal. showed that adjuvant treatment with high doses of ambroxol increased PaO 2 (weighted mean difference [WMD] = 13.73 [mmHg], 95% confidence interval [CI]: 8.68-18.79, Z = 11.80, P < 0.001), PaO 2/FiO2 (WMD = 38.81 [mmHg], 95% CI: 29.85-47.76, Z = 8.49, P = 0.000), and survival time of the deceased patients (WMD = 2.58 [d], 95% CI: 0.97-4.18, Z = 3.15, P = 0.002) compared with usual treatment. Treatment with high doses of ambroxol also appeared to reduce the hospital mortality (relative risk = 0.69, 95% CI: 0.55-0.86, Z = 3.25, P = 0.001). Conclusion: This study found that high-dose ambroxol is an effective therapy for PQ poisoning and may reduce the in-hospital mortality. In addition to this study using trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride, there are many other studies that have used trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Formula: C13H19Br2ClN2O) was used in this study.
trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4) is a mucolytic expectorant and a metabolite of bromhexine.Formula: C13H19Br2ClN2O It is used in the treatment of respiratory disorders characterized by viscous or excessive mucus.
