|Description||Dexlansoprazole, the dextrorotatory enantiomer of lansoprazole, is a proton pump inhibitor (PPI) formulated to have dual delayed-release properties.|
|Features||A modified release formulation of an enantiomer of lansoprazole.|
Dexlansoprazole, constitutes >80% of circulating drug after oral administration of lansoprazole, provides lower clearance and 5-fold greater systemic exposure than the S-enantiomer following oral administration of lansoprazole. Dexlansoprazole MR is a modified release formulation of dexlansoprazole, which employs a novel Dual Delayed Release (DDR) technology that delivers the drug in two discrete phases of release, thereby inhibiting newly activated proton pumps that turn over following initial PPI inactivation of H+,K+-ATPase. Dexlansoprazole MR maintains plasma drug concentrations above the threshold level longer than lansoprazole at all doses, resulting in an optimized drug exposure-intragastric pH relationship.  Dexlansoprazole selectively suppresses gastric acid secretion by direct inhibition of the H+K+-ATPase proton pump in the gastric parietal cell, inhibition of this cell membrane enzyme ultimately blocks the final step in acid production.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
