Although several glucose-lowering drugs have been widely used, cardio-renal complications
attract considerable attention!!!
Therefore, the drugs that provide cardio-renal protection is desired
Thus, SGLT2i can be considered
12. SGLT : Distribution & Function
Ni et al. Cardiovasc Diabetol (2020) 19:98 ; SGLT: Sodium–Glucose Co-Transporter
13. SGLT : Distribution & Function
SGLT1 : High-affinity, low-volume membrane transporter & performs 10% of glucose
re-absorption
SGLT2 : Low-affinity, high-volume membrane transporter & performs 90% of glucose
re-absorption

SGLT2 : Expression & Pharmacological Action
Approximately 160g–180g glucose is filtered from the glomerulus & reabsorbed into
the blood circulation. No urinary glucose excretion observed in healthy individuals

Diabetes Mellitus
SGLT2 : Expression & Pharmacological Action
Approximately 180g– 240g glucose reaches glomerulus for filtration. This level is much higher
than the renal glucose threshold (200 g/dl) due to which SUGAr FLOws out of the urine
Ni et al. Cardiovasc Diabetol (2020) 19:98 ; SGLT: Sodium–Glucose Co-Transporter
16. SGLT2i : Mechanism of Action
SGLT2i reduces the
glucose re-absorption
in the proximal tubule,
thus SUGAr FLOws
out of the body

To compensate for these properties, immediate release tablets
consisting of DAP with Propanediol and water (Dapagliflozin Propanediol Monohydrate)
were manufactured

7.4% water at 95% RH at 250C
In contrast, DAP-PDO-H2O uptakes 2% water at 95%
RH at 250C
• As compared to the amorphous DAP,
DAP-PDO-H2O has a multi-component crystal
structure leading to improved solubility leading to
better BA
