Description

Alginic acid is a tasteless, practically odorless, white to yellowishwhite, fibrous powder. Alginic acid found in the walls of brown seaweeds (Phaeophyceae) consists of D-mannuronic acid units and L-guluronic acid units probably linked β (1->4). The chains contain three distinct regions; in one, the D-mannuronic acid units alternate with L-guluronic acid units, whereas the remaining regions are homogeneous and contain either D-mannuronic acid or L-guluronic acid.

Storage Conditions：

Alginic acid hydrolyzes slowly at warm temperatures producing a material with a lower molecular weight and lower dispersion viscosity.
Alginic acid dispersions are susceptible to microbial spoilage on storage, which may result in some depolymerization and hence a decrease in viscosity. Dispersions should therefore be preserved with an antimicrobial preservative such as benzoic acid; potassium sorbate; sodium benzoate; sorbic acid; or paraben. Concentrations of 0.1–0.2% are usually used.

Alginic acid Use and Manufacturing

Alginic acid, also called algin or alginate, is an anionic polysaccharide distributed widely in the cell walls of brown algae, where through binding with water it forms a viscous gum. It is also a significant component of the biofilms produced by the bacterium Pseudomonas aeruginosa, the major pathogen in cystic fibrosis, that confer it a high resistance to antibiotics and killing by macrophages. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular or powdered forms.

Gastric flat film
Ingredients	This product is a compound preparation. Each tablet contains the main ingredients: 0.0125 grams of magnesium trisilicate, 0.05 grams of aluminum hydroxide, and 0.25 grams of alginate.
Indication	1 When this product is used in combination with atropine-type drugs, the absorption of the latter may be reduced, thus affecting the efficacy. 2 When this product is used in combination with digoxin, the absorption of the latter may be inhibited, and the blood concentration of the drug is reduced. 3 When this product is used in combination with diazepam-type drugs (valium), the absorption rate is reduced. 4 When used in combination with isoniazid, the absorption of isoniazid may be delayed and reduced. 5 When used in combination with levodopa, the absorption may increase, especially in those with slow gastric emptying. 6 This product should be avoided in combination with chlorpromazine, as this product can inhibit the absorption of the latter. 7 If used simultaneously with other drugs, drug interactions may occur. Please consult your physician or pharmacist for details.
