Pharmacology
Dexlansoprazole delayed-release capsule is a Proton Pump Inhibitor (PPI) which suppresses gastric acid secretion by specific inhibition of the (H+/K+)-ATPase in the gastric parietal cell. By acting specifically on the proton pump, Dexlansoprazole blocks the final step of acid production. It is the R-enantiomer of lansoprazole (A racemic mixture of the R- and S-enantiomers). Dexlansoprazole is supplied as a Dual Delayed Release (DDR) formulation in a capsule for oral administration. This capsule contains a mixture of two types of enteric coated granules with different pH-dependent dissolution profiles. The dual delayed release formulation in dexlansoprazole, plasma concentration-time profile with two distinct peaks; the first peak occurs 1 to 2 hours after administration, followed by a second peak within 4 to 5 hours. After oral administration, mean Cmax and AUC value of Dexlansoprazole increased approximately dose proportionally. Dexlansoprazole is extensively metabolized in the liver and excreated by urine.
