Most of these medications are benzimidazole derivatives, related to omeprazole, but imidazopyridine derivatives such as tenatoprazole have also been developed. [77] Potassium-competitive inhibitors such as revaprazan reversibly block the potassium-binding site of the proton pump, acting more quickly, but are not available in most countries.
Important drug interactions are rare. [38] [39] However, the most significant major drug interaction concern is the decreased activation of clopidogrel when taken together with omeprazole. [40] Although still controversial, [41] this may increase the risk of stroke or heart attack in people taking clopidogrel to prevent these events.
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]
Drug Information Portal. U.S. National Library of Medicine. U.S. National Library of Medicine. Clinical trial number NCT03198507 for "ERADICATE Hp2 - Treating Helicobacter Pylori With RHB-105 Compared to Active Comparator (ERADICATE Hp2)" at ClinicalTrials.gov
These drugs are among the most widely sold drugs in the world, and are generally considered effective. [3] When these medications are used long term, the lowest effective dose should be taken. [4] They may also be taken only when symptoms occur in those with frequent problems. [5] Proton-pump inhibitors are named using the suffix "-prazole".
The follow-up IOM report, Crossing the Quality Chasm: A New Health System for the 21st Century, advised rapid adoption of electronic patient records, electronic medication ordering, with computer- and internet-based information systems to support clinical decisions. [87] This section contains only the patient safety related aspects of HIT.
Cimetidine was the prototypical histamine H 2 receptor antagonist from which later drugs were developed. Cimetidine was the culmination of a project at Smith, Kline & French (SK&F; now GlaxoSmithKline) by James W. Black, C. Robin Ganellin, and others to develop a histamine receptor antagonist that would suppress stomach acid secretion.
When two drugs affect each other, it is a drug–drug interaction (DDI). The risk of a DDI increases with the number of drugs used. [1] A large share of elderly people regularly use five or more medications or supplements, with a significant risk of side-effects from drug–drug interactions. [2] Drug interactions can be of three kinds ...
