In the USA there are five classes of diabetic pills available as a form of treatment. Each class of drugs works in different ways to control and lower blood glucose (sugar) levels.
Sulfonylureas – has been available since the 1950’s. It helps by stimulating the beta cells of the pancreas to release more insulin. All sylfonylureas drugs have similar effects on blood glucose (sugar) levels, but they differ in side effects, how often they are taken, and interactions with other drugs.
Meglitinides – this drug also can be use to stimulate the beta cells to release insulin. Usually it is taken before each of the three meals.
Biguanides – helps to assist in lowering blood glucose (sugar) levels primarily by decreasing the amount of glucose. This form of drugs helps to lower blood glucose levels by making the muscle tissue more sensitive to insulin so glucose (sugar) can be absorbed. This drug should be taken 2 times a day. The common side effect is diarrhea, but will improve when taken with food.
