An orexin receptor antagonist, or orexin antagonist, is a drug that inhibits the effect of orexin by acting as a receptor antagonist of one (selective orexin receptor antagonist or SORA) or both (dual orexin receptor antagonist or DORA) of the orexin receptors, OX 1 and OX 2. [1]
Gastritis is the inflammation of the lining of the stomach. [1] It may occur as a short episode or may be of a long duration. [1] There may be no symptoms but, when symptoms are present, the most common is upper abdominal pain (see dyspepsia). [1]
Recent research has shown that autoimmune metaplastic atrophic gastritis (AMAG) is a result of the immune system attacking the parietal cells. [6]Environmental metaplastic atrophic gastritis (EMAG) is due to environmental factors, such as diet and H. pylori infection.
Trials in emergency department settings support the use of ondansetron to abort vomiting episodes associated with gastroenteritis and dehydration. [20] A randomized controlled trial using a single dose of oral ondansetron in children with presumably viral gastroenteritis found it to be highly effective in stopping vomiting and increasing the effectiveness of oral rehydration therapy, thereby ...
Beano contains the enzyme α-Galactosidase, specifically one derived from the fungus Aspergillus niger.The enzyme works in the digestive tract to break down the complex or branching sugars (polysaccharides and oligosaccharides) in foods such as legumes (beans and peanuts) and cruciferous vegetables (cauliflower, broccoli, cabbage, and brussels sprouts, among others).
The average age of diagnosis for GAVE is 73 years of age for females, [3] [7] and 68 for males. [2] Women are about twice as often diagnosed with gastric antral vascular ectasia than men. [2] [7] 71% of all cases of GAVE are diagnosed in females. [3] [7] Patients in their thirties have been found to have GAVE. [6]
The resulting allyl-(1-methyl-2-pentynyl) malonic ester is synthesized by subsequent alkylation of the malonic ester itself, beginning with 2-bromo-3-hexyne, which gives (1-methyl-2-pentynyl)malonic ester, and then by allylbromide. In the final step, reaction of the disubstituted malonic ester with N-methylurea gives methohexital.
In the United States it is a schedule III controlled substance [2] in some states but not federally. [5] [11] [12] It is banned in a number of European countries. [9] In 2022, the combination butalbital/acetaminophen/caffeine was the 248th most commonly prescribed medication in the United States, with more than 1 million prescriptions. [13] [14]
