Action:
Sucralfate is a locally acting gastrointestinal agent used primarily for the treatment of ulcers. It forms a protective barrier over ulcers by binding to proteins at the ulcer site and interacting with gastric acid to produce a viscous, paste-like substance. This barrier protects the ulcer from further damage by acid, pepsin, and bile salts, allowing healing to occur. Sucralfate also promotes the local release of prostaglandins and bicarbonate, which support mucosal defense and repair.
Spectrum:
Sucralfate does not possess antimicrobial activity; instead, its therapeutic effect is localized to the gastrointestinal tract, where it targets conditions involving mucosal injury. It is primarily indicated for the treatment and maintenance of duodenal ulcers, as well as for gastric ulcers. Additionally, sucralfate is used for stress ulcer prophylaxis and provides mucosal protection in conditions such as gastroesophageal reflux disease (GERD), stomatitis, and radiation-induced esophagitis.

Pharmacokinetics:
Sucralfate is a locally acting gastrointestinal agent that forms a protective barrier over damaged mucosa in the gastrointestinal (GI) tract. It is a complex of sucrose octasulfate and aluminum hydroxide, and its action is non-systemic,it works directly at the site of mucosal injury without significant absorption into the bloodstream.
Absorption
Sucralfate has a low oral bioavailability of approximately 5%, as it is considered a nonsystemic agent. Specifically, the bioavailability of sucrose octasulfate is about 5%, while aluminum is absorbed at around 0.005%. The onset of action occurs within 1 to 2 hours, and its effects can last up to 6 hours.
Metabolism
Sucralfate is not metabolized in the body.
Excretion and Elimination
It is primarily excreted unchanged in the urine. It is also dialyzable.
Sucralfate is administered orally, typically on an empty stomach, about 1 hour before meals and at bedtime for optimal effectiveness. It should be taken with water to aid dispersion and absorption at the ulcer site. Tablets should not be crushed or chewed unless specifically directed, while the suspension form should be well shaken before use.

Why do we use sucralfate?
Sucralfate is primarily used for the treatment and prevention of gastrointestinal ulcers. It is most prescribed for short-term management of active duodenal ulcers and may also be used for maintenance therapy to prevent ulcer recurrence. Additionally, it is effective in treating gastric ulcers and is often used for stress ulcer prophylaxis in hospitalized or critically ill patients. Beyond ulcers, sucralfate provides mucosal protection in conditions such as gastroesophageal reflux disease (GERD), oral and esophageal inflammation (e.g., stomatitis, esophagitis, particularly due to radiation or chemotherapy), and other forms of mucosal irritation.
