  1.  What is Dibucaine hydrochloride ?


Esomeprazole sold under the brand name Nexium among others, is a proton-pump inhibitor which reduces stomach acid. It is used in the treatment of dyspepsia, peptic ulcer disease, gastroesophageal reflux disease, and Zollinger-Ellison syndrome.

It decreases secretion of acid through inhibition of the H+/K+-ATPase in the parietal cells of the stomach. By inhibiting the functioning of this transporter, the drug prevents formation of stomach acid.

Esomeprazole is the (S)-(−)-enantiomer of omeprazole. Esomeprazole is currently sold over the counter in the US and the UK.
