Metformin: Safer for Heart Than Older Diabetes Drugs?
Study Suggests Diabetes Patients Taking Sulfonylureas Have Higher Risk of Heart Problems
Metformin vs. Sulfonylureas continued...
"The cardiovascular safety of the sulfonylureas warrants continued study," Kendall tells WebMD.
For the study, the researchers examined the potential association between treatment with a sulfonylurea or metformin and subsequent heart problems in older type 2 patients using data from electronic medical records.
Fu cautions that patients were not randomly assigned to the drugs and that the study does not prove cause and effect. Also, the analysis did not take into account whether people stopped taking their drug or if they started taking medications for high blood pressure or high cholesterol, he says.
"If you have concerns about your medication, ask your doctor," Kendall says. Never stop taking the drug on your own, he says.
These findings were presented at a medical conference. They should be considered preliminary as they have not yet undergone the "peer review" process, in which outside experts scrutinize the data prior to publication in a medical journal.
