Although cimetidine is more effective than a placebo for the prophylaxis of stress-induced ulcers, it has no advantage over titrated antacid dosing. Several comparative studies even suggest that combining cimetidine with antacid is no more effective than use of full-dose antacid. Therefore, we recommend prophylactic use of cimetidine only when very large dosages of antacid are required, in order to minimize acid-base disturbances.
尽管西咪替丁在预防应激性溃疡方面比安慰剂更有效,但与滴定抗酸剂给药相比并无优势。多项比较研究甚至表明,将西咪替丁与抗酸剂联合使用并不比使用全剂量抗酸剂更有效。因此,我们建议仅在需要非常大剂量抗酸剂时预防性使用西咪替丁,以尽量减少酸碱紊乱。
