Alginate is used as an ingredient in various pharmaceutical preparations, such as Gaviscon, in which it combines with bicarbonate to inhibit gastroesophageal reflux. [citation needed] Sodium alginate is used as an impression-making material in dentistry, prosthetics, lifecasting, and for creating positives for small-scale casting. [citation needed]
As an oral rinse, it has been used three to four times a day, with or without swallowing, providing a total amount of 150 mg/day. [10] A solution of 5% sodium alginate has been used. [10] Alternatively, it has been used as a lozenge containing 18.75 mg, four times a day. [10] It has also been used as a suppository of 75 mg with Witepsol as a ...
Alginate is initially extracted from the cell wall of brown seaweeds. Alginate dressings can be in the form of freeze-dried, porous (foam) sheets or flexible fibres. Flexible fibres are used to treat cavity wounds. The alginate will form a gel in contact with the exudates of the wound and give it a strong absorbent power. [2]
Some materials like lipids and polymers, such as alginate, may be used as a mixture to trap the material of interest inside. Most microcapsules have pores with diameters between a few nanometers and a few micrometers. Materials generally used for coating are: Ethyl cellulose; Polyvinyl alcohol; Gelatin; Sodium alginate
An immobilized enzyme is an enzyme, with restricted mobility, attached to an inert, insoluble material—such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride). This can provide increased resistance to changes in conditions such as pH or temperature.
Sodium alginate produces a medium viscosity gel but may have some aftertaste. High-methoxy pectin is one of the most widely used gelling agents in food processing. It reacts with some sugars and acids and sometimes includes minerals to improve gelling process. Low-methoxy pectin reacts with calcium, and is used for the preparation of low sugar ...
Vaginal tablets and inserts - Vaginal tablets and inserts can be used for both prevention and treatment. They dissolve in the vaginal cavity after administration. Vaginal tablets and inserts contain hydrophilic polymers such as carbomers and sodium alginate to provide a mucoadhesive properties to allow time for drug release. [5]
However, some natural occurring polymers such as chitosan, gelatin, sodium alginate, and albumin are used in some drug delivering nanocapsules. [4] Other nanocapsule shells include liposomes, [7] along with polysaccharides and saccharides. Polysaccharides and saccharides are used due to their non-toxicity and biodegradability. They are ...
