Product Parameters (Specification)

Product Features and Applications

Product Features

Low systemic absorption: Almost not absorbed through intestinal tract, only acting locally on gastrointestinal mucosa, greatly reducing heavy metal accumulation risk;

Dual therapeutic effects: Neutralize excessive gastric acid while forming a dense protective film on ulcer surfaces to block acid and pepsin irritation, and inhibit intestinal pathogenic bacteria to relieve diarrhea;

Ultra-low heavy metal control: Strictly limit copper, silver, chloride and other harmful impurities, all indexes far below USP-NF thresholds, simplifying finished drug impurity research;

Excellent formulation adaptability: Uniform powder particle size, good mixing compatibility with starch, lactose and other excipients, suitable for oral tablets, chewable tablets and compound gastrointestinal preparations.

Application Scenarios

Gastric ulcer & gastritis preparations: Core raw material for OTC stomach medicines to relieve hyperacidity, stomach burning and epigastric pain, accelerate mucosal ulcer repair;

Antidiarrheal finished drugs: Used in formulations for acute enteritis, infectious diarrhea and traveler’s diarrhea, reducing intestinal fluid secretion and slowing peristalsis;

H. pylori quadruple therapy auxiliary raw material: Combined with antibiotics and acid inhibitors to improve helicobacter eradication rate for drug-resistant strains;

External dermatological raw material: Added to ointments for mild burns, eczema and skin ulcer to exert astringent and anti-inflammatory effects;

Generic pharmaceutical projects: Standard USP-NF inorganic API for overseas factories developing low-cost gastrointestinal over-the-counter drugs.
