A comparison of sucralfate dosage schedule in duodenal ulcer healing. Two grams twice a day versus one gram four times a day.

The conventional dosage schedule for sucralfate is 1 g 4 i.d., but a dose of 2 g 2 i.d. may be equally effective in duodenal ulcer healing. We compared the efficacy of these two regimens in duodenal ulcer healing. Seventy-seven patients with endoscopically proven duodenal ulceration were entered into a double-blind, controlled study and randomized to treatment with sucralfate 2 g 2 i.d. (on waking and at bedtime) or 1 g 4 i.d. (1/2 h before meals and at bedtime). The patients were endoscoped before entry into the study, after 4 weeks, and after 8 weeks if unhealed at 4 weeks. Of the patients considered suitable for analysis at 4 weeks, 79% (26/33) of those taking 2 g 2 i.d. had healed ulcers in comparison to 72% (23/32) of those taking 1 g 4 i.d. After 8 weeks, cumulative healing rates were 85% (28/33) and 80% (24/30), respectively. The results suggest that the more convenient dosage schedule of 2 g 2 i.d. is as effective as the 1 g 4 i.d. regimen in the short-term treatment of duodenal ulcer.
