Seventy-seven patients with gastroduodenal ulcer were treated with two methyl-prostaglandin E2 analogues, m-PGE2, in a double-blind clinical trial. Each of three groups was given 15 S-15 methyl PGE2 methyl ester, 15 R-15 methyl PGE2 methyl ester, and placebo, respectively. Both forms of m-PGE2 analogues appeared to reduce gastric acid secretion, to shorten ulcer healing, and also to produce some side-effects, form 'S' being the more potent. Prompt healing of the ulcer with these agents did not prevent the recurrence of the disease. As the serum gastrin response to a meal after m-PGE2 administration was not reduced, this agent seems directly to affect oxynthic cells.
在一项双盲临床试验中,77例胃十二指肠溃疡患者接受了两种甲基前列腺素E2类似物——m-PGE2的治疗。三组患者分别给予15 - S-15甲基前列腺素E2甲酯、15 - R-15甲基前列腺素E2甲酯和安慰剂。两种形式的m-PGE2类似物似乎都能减少胃酸分泌、缩短溃疡愈合时间,并且还会产生一些副作用,“S”型的效力更强。这些药物使溃疡迅速愈合,但并不能预防疾病复发。由于给予m-PGE2后血清胃泌素对进餐的反应并未降低,因此该药物似乎直接作用于泌酸细胞。
