Pharmacodynamics
Esomeprazole is the S-isomer of Omeprazole. It acts as a proton pump inhibitor that suppresses
gastric acid secretion by specific inhibition of the H+/K+-ATPase in the gastric parietal cell. By acting
specifically on the proton pump, Esomeprazole blocks the final step of acid production, thus
reducing gastric acidity.
Pharmacokinetics
Absorption
Bioavailability is approximately 90% (repeated once daily dosing) and 64% (single dose).
Distribution
Esomeprazole is 97% bound to plasma proteins. The apparent volume of distribution at steady state
in healthy volunteers is approximately 16 L.
Metabolism
Esomeprazole is extensively metabolized in the liver by the cytochrome P450 (CYP) enzyme
system.
Excretion
Esomeprazole is excreted as metabolites primarily in urine but also in feces. Less than 1% of parent
drug is excreted in the urine.
