Hong Kong No.1 Selling Gastrointestinal Drug
Unique "Dual-Layer, Multi-Action" Tablets
Over 65 Years of History
PIC/S & GMP Quality
Weisen-U is a dual-layer tablet consisting of an inner core and an outer layer. This formulation produces a synergistic effect - the strong antacid in the outer layer dissolves quickly after intake and neutralizes excessive gastric acid. Afterwards, the inner layer penetrates the damaged sections of the stomach and quickly treats the affected area. This formulation not only quickly relieves stomach discomfort but also restores the damaged stomach and promotes health recovery.

The Dual Layer Structure
Unlike conventional gastrointestinal drugs, Weisen-U has a unique dual layer. Dissolving at different phases, the inner core and outer layer work in synergy to address different gastrointestinal problems.

Neutralizes Gastric Acid: “Weisen-U”, with a powerful antacid, quickly neutralizes gastric acid, relieves pain, and provides symptomatic relief.

Alleviating The Digestive System: Biodiastase2000, which is contained in the outer layer of the tablet, promotes digestion and absorption of starch in the stomach, alleviating the load on the digestive system.

Restores Damaged Gastric Mucosa: The gastric-protective agent Methylmethionine Sulfonium Chloride (Vitamin U) in "Weisen-U" helps repair and heal damaged gastric mucosa, restoring stomach health.
