Twenty-five patients with healed gastric ulcers completed an 11-month double-blind controlled trial comparing cimetidine 1 g daily with placebo in the prevention of ulcer relapse. Ulcers recurred in 14 patients, 12 on placebo, 2 on cimetidine. In 11 patients, 9 on cimetidine, 2 on placebo, the ulcers remained healed at the end of the trial (P less than 0.002). Cimetidine 1 g daily significantly reduces the relapse rate in gastric ulceration.
25例胃溃疡已愈合的患者完成了一项为期11个月的双盲对照试验,比较每日1克西咪替丁与安慰剂预防溃疡复发的效果。14例患者溃疡复发,其中12例服用安慰剂,2例服用西咪替丁。11例患者溃疡未复发,其中9例服用西咪替丁,2例服用安慰剂(P<0.002)。每日1克西咪替丁可显著降低胃溃疡的复发率。
