Pharmacokinetic data: DrugBank · CC BY-NC 4.0
Acarbose is one of only two approved alpha-glucosidase inhibitors (the other being [miglitol]), receiving its first FDA approval in 1995 under the brand name Precose (since discontinued).[L31668] This class of antidiabetic therapy is not widely used due to their relatively modest impact on A1c, their requirement for thrice-daily dosing, and the potential for significant gastrointestinal adverse effects.[L31668]

In the event of an overdose, patients should be instructed to avoid carbohydrate-containing foods for 4-6 hours following administration as these can precipitate the aforementioned GI symptoms.
[L31628]
Acarbose is a complex oligosaccharide that competitively and reversibly inhibits both pancreatic alpha-amylase and membrane-bound alpha-glucosidases - of the alpha-glucosidases, inhibitory potency appears to follow a rank order of glucoamylase > sucrase > maltase > isomaltase.[L31633] By preventing the metabolism and subsequent absorption of dietary carbohydrates, acarbose reduces postprandial blood glucose and insulin levels.
Given its mechanism of action, acarbose in isolation poses little risk of contributing to hypoglycemia - this risk is more pronounced, however, when acarbose is used in conjunction with other antidiabetic therapies (e.g. sulfonylureas, insulin).[L31633] Patients maintained on acarbose in addition to other antidiabetic agents should be aware of the symptoms and risks of hypoglycemia and how to treat hypoglycemic episodes. There have been rare post-marketing reports of the development of pneumatosis cystoides intestinalis following treatment with alpha-glucosidase inhibitors - patients experiencing significant diarrhea/constipation, mucus discharge, and/or rectal bleeding should be investigated and, if pneumatosis cystoides intestinalis is suspected, should discontinue therapy.[L31628]
How the body processes this drug — absorption, distribution, metabolism, and elimination
[L31628]
[L31628]
[L31633]
[L31628]
Only one metabolite - resulting from the cleavage of a glucose molecule from acarbose - has been identified as having alpha-glucosidase inhibitory activity.
[L31628]
[L31633]
What little drug material is absorbed into the systemic circulation (approximately 34% of an orally administered dose) is excreted primarily by the kidneys, suggesting renal excretion would be a significant route of elimination if the parent drug was more readily absorbed - this is further supported by data in which approximately 89% of an intravenously administered dose of acarbose was excreted in the urine as active drug (in comparison to <2% following oral administration) within 48 hours.
