Hello, Thanks for the query. You are right, both medicines contain Metformin as one of the ingredient, but Glycomet GP1 has 1 mg of Glimiperide and the other (Ozomet G2) has 2 mg of glimileride. The reduction in blood glucose level noticed is due to the higher dose of Glimiperide. This drug stimulates Beta cells in pancreas to synthesise Insulin. Higher dose means there a greater stimulation. Still the blood glucose levels (Fasting 130 mg & PP 240 mg) are much higher than ideal levels in case of good control like Fasting closer to 100mg, PP 150 to 160 mg and HbA1c% Therefore, it is necessary to improve the current treatment so that desired blood glucose levels are achieved consistently. I am sure you are aware it is essential to achieve a very strict blood glucose control in order to postpone or prevent long term complications of diabetes affecting various vital organ in the body. In addition to specific drugs, it is very essential to take a restricted diet, that gives exact calories based on ideal body weight, extent of daily exercise and blood glucose levels. Avoid sweets, deep fried foods, pastries, other bakery items and sweetened aerated drinks (colas) and sweet corn syrup containing food products. Consume more of green leafy vegetables and salads. Also exercise daily for at least 1 hour, brisk walking is a good option. I will be glad to guide if desire so, thanks.
