Graphene (/ËÉ¡rÃ¦f.iËn/) is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes.
Proton pump inhibitors are a type of acid reducer that helps to decrease levels of acid in your stomach. They work by causing your body to make less stomach acid. This helps to treat heartburn and acid reflux problems. Another type of acid reducer, in addition to a proton pump inhibitor, is an H2 blocker.
Proton-pump inhibitors (PPIs) are a group of drugs whose main action is a pronounced and long-lasting reduction of gastric acid production.They are the most potent inhibitors of acid secretion available.igh dose and/or long-term use of PPIs carries a possible increased risk of bone fractures which was not found with short-term, low dose use; the FDA included a warning regarding this on PPI drug labels in 2010.
