Antepsin® 1 g/5 mL Suspension contains sucralfate, a medication commonly used to treat and protect the lining of the stomach and intestines. Doctors primarily prescribe this medicine to treat gastric and duodenal ulcers.
Sucralfate works by forming a protective barrier over ulcerated or damaged areas in the gastrointestinal tract. As a result, the protective layer shields the affected tissue from stomach acid, bile salts, and digestive enzymes. Consequently, it supports the healing process of the ulcer.

Doctors often prescribe Antepsin suspension to relieve symptoms such as stomach pain, irritation, and discomfort caused by ulcers or gastritis. In addition, doctors may prescribe this medicine to prevent ulcer recurrence in certain patients.
Each 5 mL of suspension contains:
Sucralfate – 1 g
The formulation may also contain inactive ingredients (excipients) that help maintain stability, improve taste, and ensure proper suspension consistency.
Sucralfate acts as a gastroprotective agent. Unlike acid-reducing medicines, it mainly works by protecting the stomach lining.
After oral administration and contact with stomach acid:
Sucralfate forms a viscous, gel-like protective layer
This layer binds to ulcerated tissue
The protective coating shields the ulcer from stomach acid and enzymes
Tissue healing is therefore supported and accelerated
Additionally, sucralfate may stimulate the production of prostaglandins and mucus, which further helps protect the gastrointestinal lining.
Doctors prescribe Antepsin® 1 g/5 mL Suspension for the treatment and management of several gastrointestinal conditions, including:
Duodenal ulcers
Gastric ulcers
Gastritis
Gastroesophageal reflux disease (GERD)
Prevention of ulcer recurrence
Protection of the stomach lining in patients at risk of ulcers
However, treatment decisions are always based on clinical evaluation and medical advice.
