An enteric coating is a polymer barrier applied to oral medication that prevents its dissolution or disintegration in the gastric environment. [1] This helps by either protecting drugs from the acidity of the stomach, the stomach from the detrimental effects of the drug, or to release the drug after the stomach (usually in the upper tract of the intestine). [2]
The gene transfer occurs when the plant signals are induced and physical contact is made between the plant cells and the bacteria. The bacteria create a mechanism that burrows a hole and transfers the new T-DNA strand into the plant cell. The T-DNA moves into the nucleus of the plant and begins to integrate into the plants' chromosome.
However, stomach acids destroyed trypsin. The patentee proposed and claimed coating trypsin with an enteric coating (stomach-acid-resistant coating), which permitted the trypsin to pass through the stomach to the small intestine without damage to be absorbed and then, it would act as an anti-inflammatory or analgesic. However, the enteric ...
Cellulose acetate phthalate (CAP), also known as cellacefate and cellulosi acetas phthalas, is a commonly used polymer phthalate in the formulation of pharmaceuticals, such as the enteric coating of tablets or capsules and for controlled release formulations.
Thick coatings may accommodate additional features such as fertilizers, plant hormones, plant-beneficial microbes, and water-retaining polymers. [1] [4] Specialist machinery is required to safely and efficiently apply the chemical to the seed. [5] A cement mixer is enough for non-hazardous coating materials. [4]
Capsule contents may be released by melting the wall, or dissolving it under particular conditions, as in the case of an enteric drug coating. [7] In other systems, the wall is broken by solvent action, enzyme attack, chemical reaction, hydrolysis, or slow disintegration. Microencapsulation can be used to slow the release of a drug into the body.
It is available as delayed-release capsules or tablets and as esomeprazole sodium for intravenous injection/infusion. Oral esomeprazole preparations are enteric-coated, due to the rapid degradation of the drug in the acidic condition of the stomach. This is achieved by formulating capsules using the multiple-unit pellet system.
A plant cuticle is a protecting film covering the outermost skin layer of leaves, young shoots and other aerial plant organs (aerial here meaning all plant parts not embedded in soil or other substrate) that have no periderm. The film consists of lipid and hydrocarbon polymers infused with wax, and is synthesized exclusively by the epidermal cells.
