Xigduo XR Description

XIGDUO XR (dapagliflozin propanediol monohydrate/metformin hydrochloride) extended-release tablets contain two oral antihyperglycaemic drugs used in the management of type 2 diabetes: dapagliflozin propanediol monohydrate and metformin hydrochloride.
Dapagliflozin: Dapagliflozin propanediol monohydrate is an orally-active inhibitor of the human renal sodium-glucose co-transporter 2 (SGLT2), the major transporter responsible for renal glucose reabsorption. Dapagliflozin is described chemically as (1S)-1,5-Anhydro-1-C-[4-chloro-3-[(4-ethoxyphenyl)methyl]phenyl]-D-glucitol, (S)-propylene glycol, monohydrate.
Molecular formula: C₂₁H₂₅ClO₆·C₃H₈O₂·H₂O.
Molecular weight: 502.98.
CAS Number: 960404-48-2.
Dapagliflozin drug substance is a white to off-white powder, is non-hygroscopic, crystalline. Dapagliflozin is non-ionisable; thus, its aqueous solubility and partition coefficient are not affected by changes in pH. Dapagliflozin is a Biopharmaceutical Classification System (BCS) Class III drug.
Metformin hydrochloride: Metformin hydrochloride (N,N-dimethylimidodicarbonimidic diamide hydrochloride) is a biguanide with antihyperglycaemic effects.
Molecular formula: C₄H₁₁N₅·HCl.
Molecular weight: 165.63.
CAS number: 1115-70-4.
Metformin hydrochloride is a white to off-white crystalline compound. Metformin hydrochloride is freely soluble in water, slightly soluble in alcohol, and is practically insoluble in acetone, ether, and chloroform. The pKa of metformin is 12.4. The pH of a 1% aqueous solution of metformin hydrochloride is 6.68.
XIGDUO XR is available for oral administration as tablets containing the following active ingredients: XIGDUO XR 5/1000: 5 mg dapagliflozin (as dapagliflozin propanediol monohydrate) and 1000 mg metformin hydrochloride.
XIGDUO XR Tablet 10/1000: 10 mg dapagliflozin (as dapagliflozin propanediol monohydrate) and 1000 mg metformin hydrochloride.
