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. A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes. Proton pump inhibitors act by irreversible inhibition of the H+/K+ ATPase, in the parietal cells of the stomach. It markedly inhibits gastric acid secretion and has a long duration of action.
