The FDA has approved vonoprazan (Voquezna – Phathom), a potassium-competitive acid blocker, for healing and maintenance of healing of all grades of erosive esophagitis and relief of associated heartburn in adults. Vonoprazan is also available copackaged with amoxicillin (Voquezna Dual Pak) and with amoxicillin and clarithromycin (Voquezna Triple Pak) for treatment of Helicobacter pylori infection in adults.

The FDA has approved the marketing of Vimovo (AstraZeneca), a fixed-dose combination of the nonsteroidal anti-inflammatory drug (NSAID) naproxen and the proton pump inhibitor (PPI) esomeprazole, for symptomatic relief of osteoarthritis, rheumatoid arthritis and ankylosing spondylitis and to decrease the risk of developing gastric ulcers in patients at risk for NSAID-associated ulcers.

Use of proton pump inhibitors (PPIs) to treat gastroesophageal reflux disease (GERD) has been associated with an increase in the risk of fractures. The FDA now requires that the labels of all prescription PPIs include a warning about an increased risk of fractures with long-term use.

A recent advertisement for the proton pump inhibitor (PPI) lansoprazole (Prevacid - TAP) suggests that children who cough at night, complain of abdominal pain, refuse to eat, or have a bad taste in their mouths may all have gastroesophageal reflux disease (GERD). A Bunny's Tummy Trouble, a children's book about GERD published by TAP, is now available as a patient handout in pediatricians' waiting rooms. The use of acid-suppressive drugs in infants and children has increased markedly in recent years and many of these drugs are now available in child-friendly formulations. A table in the article...

The FDA has warned that prolonged use of a proton pump inhibitor (PPI) can lead to hypomagnesemia.1 Normal serum concentrations of magnesium are 0.7-1.0 mmol/L. About 30 cases of severe hypomagnesemia (<0.5 mmol/L) have been reported in long-term PPI users; when the PPI was stopped, serum magnesium levels returned to normal in less than 2 weeks.2-5 The exact mechanism is unknown, but in some patients PPIs apparently interfere with active transport of magnesium across the intestinal wall or cause excessive loss into the intestinal lumen.6 Hypomagnesemia is often accompanied by hypocalcemia...

The FDA has approved the proton-pump inhibitor (PPI) dexlansoprazole (Kapidex - Takeda), a delayed release formulation of the R-enantiomer of lansoprazole (Prevacid - Takeda), for treating and maintaining healing of erosive esophagitis and for treatment of heartburn associated with non-erosive gastroesophageal reflux disease (GERD).

Recently pharmaceutical manufacturers have marketed a stereoisomer of a successful drug nearing patent expiration as a new drug. Examples, such as esomeprazole (Nexium) , levalbuterol (Xopenex), escitalopram (Lexapro) and dexmethylphenidate

With the removal of Vioxx from the market and concerns about cardiovascular toxicity with other selective COX-2 inhibitors, patients are looking for safe alternatives, and manufacturers of other drugs are looking for additional market share. The COX-2 inhibitors first became popular because they have less upper GI toxicity than older less selective NSAIDs, at least in the short term, in patients not taking aspirin.

The FDA has approved the proton pump inhibitor (PPI) esomeprazole strontium for use in adults for the same indications as esomeprazole magnesium (Nexium): treatment of gastroesophageal reflux disease (GERD), prevention of NSAID-induced gastric ulcers, eradication of Helicobacter pylori, and treatment of pathological hypersecretory conditions. It was first marketed in December 2013 as a branded drug (Esomeprazole Strontium) and a month later as a generic drug.Strontium is incorporated into bone. It is not recommended for use in children or during pregnancy because of the absence of safety data...
