Omeprazole was a subject of a patent litigation in the U.S. [66] The invention involved application of two different coatings to a drug in pill form to ensure that the omeprazole did not disintegrate before reaching its intended site of action in stomach. Although the solution by means of two coating was obvious, the patent was found valid ...
A derivative of timoprazole, omeprazole, was discovered in 1979, and was the first of a new class of drug that control acid secretion in the stomach, a proton pump inhibitor (PPI). [11] [12] Addition of 5-methoxy-substitution to the benzimidazole moiety of omeprazole was also made and gave the compound much more stability at neutral pH. [6]
The drugs and the enzymes they probe are as follows - caffeine (probes CYP1A2, N-acetyltransferase 2, xanthine oxidase), midazolam (probes CYP3A), omeprazole (probes CYP2C19) and dextromethorphan (probes CYP2D6). After giving the cocktail, the concentrations of the drugs and their metabolites in plasma (for midazolam and omeprazole) and urine ...

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).

Omeprazole is a popular drug that conforms to Lipinski's rule of five. Some authors have criticized the rule of five for the implicit assumption that passive diffusion is the only important mechanism for the entry of drugs into cells, ignoring the role of transporters. For example, O'Hagan and co-authors wrote as follows: [5]
