The most effective diabetes drugs don't reach enough patients yet

A new study found that the newer generation of effective diabetes medications are not reaching enough patients. The study analyzed data from over 40,000 records and found that only 20% of patients with type 2 diabetes were taking GLP-1 drugs within a year of diagnosis, and less than 15% were taking SGLT2 drugs.

Two Type 2 diabetes drugs linked to higher risk of heart disease

A Northwestern Medicine study found that sulfonylureas and basal insulin increase the risk of heart attack, stroke, and amputation in patients with Type 2 diabetes. The study suggests a paradigm shift in treatment, recommending newer diabetes medications with more favorable cardiovascular profiles.

Researchers change clinical practice for infants with diabetes

A recent study found that infants with diabetes can maintain excellent blood glucose control for up to ten years using sulfonylurea tablets, offering a promising alternative to insulin injections. The treatment has been shown to be safe and effective in children worldwide.

Photopharmacology: Optical control of insulin secretion

A team of scientists has successfully created a light-sensitive sulfonylurea compound that stimulates insulin release only in response to blue light. This breakthrough could lead to more precise control over blood sugar levels and reduce side effects associated with traditional diabetes treatments.

Late-breaking observational data show patients with type 2 diabetes taking JANUVIA (sitagliptin) and metformin initiated insulin therapy at a slower rate compared to patients taking a sulfonylurea and metformin

A retrospective cohort study found patients taking JANUVIA and metformin initiated insulin therapy at a slower rate than those taking a sulfonylurea and metformin. The study suggests that real-world data may provide insight into the effects of different oral treatment regimens on the initiation of insulin use.

New analysis shows that patients with Type 2 diabetes and mild renal impairment had similar improvement in blood sugar control and experienced less hypoglycemia with JANUVIA (sitagliptin) compared to sulfonylurea

A post-hoc analysis found that patients with Type 2 diabetes and mild renal impairment treated with JANUVIA achieved similar blood sugar reductions as those treated with sulfonylureas, with significantly fewer hypoglycemia events. Patients taking JANUVIA also experienced weight loss, whereas those on sulfonylureas gained weight.

Common diabetes drugs associated with increased risk of death

A large analysis found that three widely used diabetes medications - glipizide, glyburide, and glimepiride - are associated with a greater risk of death compared to metformin. These sulfonylureas were linked to a 50% increased risk of mortality, while glimepiride appeared to be safer in patients with heart disease.

Drugs may be 'magic bullet' for infants born with rare form of diabetes

A new study found that sulfonylurea drugs can restore function and reverse symptoms in infants with neonatal diabetes by blocking potassium channels, potentially avoiding secondary damage to insulin-producing cells. Early treatment with these drugs may circumvent irreversible damage if caught early enough.

Moderate use averts failure of type 2 diabetes drugs in animal model

In an animal model, sulfonylureas' effects were found to be reversible after cessation, suggesting beta cells can recover and produce insulin again. This finding may lead to rethink treatment strategies, such as using older drugs or alternating periods of drug treatment with insulin injections.

Risks of sulfonylurea drugs in the treatment of diabetes mellitus

A large cohort study found that sulfonylurea drugs increase the risk of mortality and cardiac events in patients with type 2 diabetes. The study suggests that sulfonylureas should be used only as a third-line treatment option, due to their potential to harm heart muscle.

Common diabetes drug causes arteries to spasm, endangering heart

Researchers discovered a direct link between sulfonylurea drugs and coronary arterial spasm, increasing blood pressure and heart damage. The study suggests that these common diabetes medications may pose an additional risk to diabetic patients already facing cardiovascular problems.
