Medications used to treat diabetes do so by lowering blood sugar levels. There are a number of different classes of anti-diabetic medications. Some are available by mouth, such as metformin, while others are only available by injection like insulin. Type 1 diabetes can only be treated with insulin, typically with a combinations of regular and NPH insulin, or synthetic insulin analogs.[citation needed]

Metformin is generally recommended as a first line treatment for type 2 diabetes, as there is good evidence that it decreases mortality.[57] It works by decreasing production of glucose by the liver.[58] Several other groups of drugs, mostly given by mouth, may also decrease blood surgar in type II DM. These include agents that increase insulin release, agents that decrease absorption of sugar from the intestines, and agents that make the body more sensitive to insulin.[58] When insulin is used in type 2 diabetes, a long-acting formulation is usually added initially, while continuing oral medications.[57] Doses of insulin are then increased to effect.[57]

Since cardiovascular disease is a serious complication associated with diabetes, some recommend blood pressure levels below 120/80 mmHg;[59][60] however, evidence only supports less than or equal to somewhere between 140/90 mmHg to 160/100 mmHg.[61][62] Amongst medications that lower blood pressure, angiotensin converting enzyme inhibitors (ACEIs) improve outcomes in those with DM while the similar medications angiotensin receptor blockers (ARBs) do not.[63] Aspirin is also recommended for patient with cardiovascular problems, however routine use of aspirin has not been found to improve outcomes in uncomplicated diabetes.

So I guess this is where the internet comes in.
