Fifty patients with exacerbations of chronic bronchitis were treated with either a combination of trimethoprim 320 mg. and sulphamethoxazole 1,600 mg. a day or ampicillin 2 g. a day. The trial, carried out as a single-blind procedure, showed that the combination was more effective as judged by clinical response and reduction in sputum volume and purulence, with eradication of pathogenic organisms. No appreciable side-effects were encountered with either treatment, and it is suggested that the trimethoprim-sulphamethoxazole combination may be a safe and useful drug in the treatment of chronic bronchitis.
50例慢性支气管炎急性发作患者分别接受以下治疗:每日服用甲氧苄啶320毫克与磺胺甲恶唑1600毫克的组合,或每日服用2克氨苄西林。该试验采用单盲程序进行,结果显示,从临床反应、痰液量减少以及痰液脓性减轻并根除致病微生物的角度判断,上述组合更为有效。两种治疗方法均未出现明显副作用,有人认为甲氧苄啶 - 磺胺甲恶唑组合可能是治疗慢性支气管炎的一种安全有效的药物。
