Sucralfate is a medication commonly used to treat ulcers and other gastrointestinal disorders. It is a complex of sulfated sucrose and aluminum hydroxide, which works by forming a protective barrier over the ulcer site, preventing further damage and allowing the ulcer to heal. Other synonyms for sucralfate include carafate, sucralfato, and sulcrate. The medication is available in tablet and liquid form, and is typically taken orally before meals or at bedtime. It may take up to eight weeks for the ulcer to completely heal with sucralfate treatment, but many patients report relief from their symptoms within a few days of starting the medication.
