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.
Introduction Proton pump inhibitors (PPI), the most potent inhibitors of gastric acid secretion, have revolutionized the treatment of acid-related disorders, including gastroesophageal reï¬ ux disease, peptic ulcer disease, and gastropathy induced by nonsteroidal anti-inï¬ ammatory drugs (NSAIDs).
