Bedtime H2 blockers improve nocturnal gastric acid control in GERD patients on proton pump inhibitors.
The group scanned the databases for patients who were prescribed proton pump inhibitors or other drugs, such as H2 blockers, and also looked to see if a given patient had a mention of having experienced a major cardiovascular event, such as myocardial infarction (heart attack), in their medical record.
A 2015 study also found an association between PPIs and an elevated risk for heart attack (no association was seen with H2 blockers), while more recent research (British Journal of Clinical Pharmacology, Jan 5), found that people who took PPIs or H2 blockers had a greater risk of infection with C.
If someone has heartburn and the symptoms disappear when they take a PPI, they should try to see if a safer H2 blocker works.
The scientists found no such association with another class of stomach-acid-reducing drugs known as histamine 2 receptor antagonists, or H2 blockers, which include cimetidine (Tagamet[R]), famotidine (Pepcid[R]), nizatidine (Axid[R]), and ranitidine (Zantac[R]).

The suspect drugs feature the suffix"-prazole"--for example, omeprazole and lansoprazole--and are different from another antacid drug class known as an H2 blocker (cimetidine, ranitidine), which is not linked to increased risk of heart attack.
The common risk factor predisposing to early onset VAP was use of H2 blocker (65%), Ryle's tube feeding (65%), steroids (28%), surgical intervention (24%), DM (4%).
A two or more years' prescription for a PPI was associated with a 65 percent greater risk of vitamin B12 deficiency, while the same prescription for an H2 blocker was linked to a 25 percent increased risk, according to the study, published Dec.
