Safety and Effectiveness of Sodium-Glucose Co-transporter 2 Inhibitors on Glycemic Control in Patients with Type 2 Diabetes Mellitus Fasting during Ramadan: A Review.

This review evaluates the current evidence on the safety and efficacy of sodium-glucose cotransporter 2 (SGLT2) inhibitors for patients with type 2 diabetes mellitus (T2DM) fasting during Ramadan. All studies included in the review were conducted in Asia and the Middle East. Overall, the evidence suggests that SGLT2 inhibitors are a safe and effective treatment option for most T2DM patients fasting during Ramadan. The average incidence of symptomatic hypoglycemia is 12.5%, but ranges from 0.7% to 27%, depending on the study population and concomitant use of other medications. The risk of hypoglycemia is increased when SGLT2 inhibitors are used in combination with insulin and/or sulfonylureas. Therefore, patients taking SGLT2 inhibitors in combination with insulin and/or sulfonylureas can take steps to mitigate this risk, such as having their insulin and/or sulfonylurea doses adjusted and being closely monitored for hypoglycemia. Patients taking SGLT2 inhibitors may be at increased risk of dehydration. To mitigate the risk of dehydration, patients should be advised to consume adequate fluids during the fast-breaking hours. Further research is warranted to validate these findings and extend their applicability to high-risk populations and other regions of the world.
