Precose is the brand name for acarbose, an oral medication used to control blood glucose in patients with type 2 diabetes. The drug belongs to the class of alpha-glucosidase inhibitors. It works by slowing the digestion of carbohydrates in the small intestine, which reduces the rise of blood sugar after meals. By inhibiting the enzyme that breaks down complex sugars, it delays their absorption into the bloodstream. This delay leads to a more gradual increase in glucose levels, helping to improve overall glycemic control. The therapeutic purpose of Precose is to complement diet and exercise in managing hyperglycemia. Its mechanism of action involves binding to the active site of intestinal alpha-glucosidase, preventing the breakdown of starches and sucrose. The overall effect is a modest but clinically meaningful decrease in postprandial glucose excursions.

Precose is an oral antidiabetic medication that belongs to the class of a-glucosidase inhibitors. It is prescribed to improve glycemic control in patients with type 2 diabetes. The drug works by slowing the breakdown of carbohydrates in the intestine which reduces glucose absorption. This effect leads to a modest decrease in postprandial blood sugar levels. By lowering the rise of glucose after meals the medication supports overall glycemic management. The pharmacodynamic action involves inhibition of the enzyme that hydrolyzes complex sugars into simple sugars. The resulting suppression of carbohydrate digestion contributes to the therapeutic outcome of reduced hyperglycemia

Precose may cause gastrointestinal discomfort such as diarrhea and abdominal pain. It can also lead to dizziness or headache in some patients. Hypoglycemia is possible when Precose is used with other glucose-lowering agents. Elevated liver enzymes have been reported rarely. Swelling of the extremities is an uncommon occurrence. Skin reactions such as rash may appear infrequently.

Precose may cause gastrointestinal disturbances such as gas and bloating. It can lead to diarrhea or loose stools in some patients. Abdominal discomfort or pain is occasionally reported. Some individuals experience nausea or a feeling of fullness. Rarely liver enzyme elevations may occur without noticeable symptoms. Hypoglycemia can develop when Precose is combined with other glucose-lowering agents. Most side effects are mild and often improve with continued use.
