Rosiglitazone and Metformin: Hemoglobin A1c
Hemoglobin A1c (HbA1c) is a test used to measure long-term blood sugar control. For people without
diabetes, HbA1c results are usually less than 6 percent, while people with diabetes usually have higher results. In one study, people taking
rosiglitazone and
metformin lowered their HbA1c by up to 2.3 percent on average. In the same study, people taking metformin or rosiglitazone alone did not lower their HbA1c as much as people taking rosiglitazone and metformin.
Studies have shown that the higher the HbA1c, the greater the chance for developing long-term problems related to diabetes. This includes such problems as
heart disease,
diabetic retinopathy,
diabetic neuropathy, and diabetic nephropathy. By getting blood sugar levels under control with rosiglitazone and metformin, it may be possible to decrease the chances for developing these
diabetes complications.
Rosiglitazone and Metformin: Fasting Blood Sugar
Fasting blood sugar is another way to study the effects of
diabetes drugs. In studies, people taking rosiglitazone and metformin decreased their fasting blood sugar levels by 74 mg/dL on average, while people taking metformin or rosiglitazone alone lowered their fasting blood sugar levels by only 47 to 51 mg/dL on average.
