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).

Aspirin acts as an acetylating agent where an acetyl group is covalently attached to a serine residue in the active site of the COX enzyme. [1] This makes aspirin different from other NSAIDs (such as diclofenac and ibuprofen), which are reversible inhibitors; aspirin creates an allosteric change in the structure of the COX enzyme. [2]
A popular example of drug–food interaction is the effect of grapefruit on the metabolism of drugs. Interactions may occur by simultaneous targeting of receptors, directly or indirectly. For example, both Zolpidem and alcohol affect GABA A receptors, and their simultaneous consumption results in the overstimulation of the receptor, which can ...
This differs from a mechanism of action since it is a more specific term that focuses on the interaction between the drug itself and an enzyme or receptor and its particular form of interaction, whether through inhibition, activation, agonism, or antagonism. Furthermore, the term "mechanism of action" is the main term that is primarily used in ...
By 1899, Bayer had dubbed this drug Aspirin and was selling it globally. [15]: 27 The word Aspirin was Bayer's brand name, rather than the generic name of the drug; however, Bayer's rights to the trademark were lost or sold in many countries. Aspirin's popularity grew over the first half of the 20th century leading to fierce competition with ...
Aspirin helps prevent blood clots from forming, which is the leading cause of heart attack and stroke, but the drug also carries a risk of bleeding. That risk can outweigh aspirin’s benefits in ...
Enteric coated tablets are designed to dissolve in the intestine, not the stomach, because the drug present in the tablet causes irritation in the stomach. Administering medication rectally The rectal route is an effective route of administration for many medications, especially those used at the end of life .
Antacids would increase the pH environment in the stomach and cause premature release of enteric coated drugs, which are designed to be protected from an acidic environment in stomach. [21] For example, proton-pump inhibitors (PPIs) are enteric coated to protect them from decomposition under an acidic environment. [22]
