Dexlansoprazole, sold under the trade names Dexilant and Biozodex among others, is a medication which reduces stomach acid. It is used to treat gastroesophageal reflux disease. Effectiveness is similar to other proton pump inhibitors (PPIs). It is taken by mouth.Common side effects include diarrhea, abdominal pain, and nausea. Serious side effects may include osteoporosis, low blood magnesium, Clostridium difficile infection, anaphylaxis, and pneumonia. Use in pregnancy and breastfeeding is of unclear safety. It works by blocking H+/K+-ATPase in the parietal cells of the stomach.Dexlansoprazole was approved for medical use in the United States in 2009. In Canada in 2016, it was the most expensive PPI available. In 2019, it was the 218th most commonly prescribed medication in the United States, with more than 2 million prescriptions. Medical use
Dexlansoprazole is used to heal and maintain healing of erosive esophagitis and to treat heartburn associated with gastroesophageal reflux disease (GERD). It lasts longer than lansoprazole, to which it is chemically related, and needs to be taken less often. There is no good evidence that it works better than other PPIs. Adverse effects
The most significant adverse reactions (≥2%) reported in clinical trials were diarrhea, abdominal pain, bloating, nausea, upper respiratory tract infection, vomiting, and flatulence. Mechanism of action
Like lansoprazole, dexlansoprazole permanently binds to the proton pump and blocks it, preventing the formation of gastric acid. Chemistry
Dexlansoprazole is the (R)-(+)-enantiomer of lansoprazole, which is a racemic mixture of its (R)-(+) and (S)-(−)-enantiomers.
Blood blisters can also occur in the mouth for a variety of reasons including side effects to certain medications, nutritional deficiencies, and mouth injuries. Treatment
There are several methods of healing blood blisters, including elevation of the wound combined with application of a cold pack, and application of padded dressings or splints. See also
