ACARBOSE VIATRIS 100 mg

INDICATIONS AND USAGE Acarbose Tablets are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

DOSAGE AND ADMINISTRATION There is no fixed dosage regimen for the management of diabetes mellitus with Acarbose Tablets or any other pharmacologic agent. Dosage of Acarbose Tablets must be individualized on the basis of both effectiveness and tolerance while not exceeding the maximum recommended dose of 100 mg t.i.d. Acarbose Tablets should be taken three times daily at the start (with the first bite) of each main meal. Acarbose Tablets should be started at a low dose, with gradual dose escalation as described below, both to reduce gastrointestinal side effects and to permit identification of the minimum dose required for adequate glycemic control of the patient. If the prescribed diet is not observed, the intestinal side effects may be intensified. If strongly distressing symptoms develop in spite of adherence to the diabetic diet prescribed, the doctor must be consulted and the dose temporarily or permanently reduced. During treatment initiation and dose titration (see below), one-hour postprandial plasma glucose may be used to determine the therapeutic response to Acarbose Tablets and identify the minimum effective dose for the patient. Thereafter, glycosylated hemoglobin should be measured at intervals of approximately three months. The therapeutic goal should be to decrease both postprandial plasma glucose and glycosylated hemoglobin levels to normal or near normal by using the lowest effective dose of Acarbose Tablets, either as monotherapy or in combination with sulfonylureas, insulin or metformin. Initial Dosage The recommended starting dosage of Acarbose Tablets is 25 mg given orally three times daily at the start (with the first bite) of each main meal. However, some patients may benefit from more gradual dose titration to minimize gastrointestinal side effects. This may be achieved by initiating treatment at 25 mg once per day and subsequently increasing the frequency of administration to achieve 25 mg t.i.d. Maintenance Dosage Once a 25 mg t.i.d. dosage regimen is reached, dosage of Acarbose Tablets should be adjusted at 4-8 week intervals based on one-hour postprandial glucose or glycosylated hemoglobin levels, and on tolerance. The dosage can be increased from 25 mg t.i.d. to 50 mg t.i.d. Some patients may benefit from further increasing the dosage to 100 mg t.i.d. The maintenance dose ranges from 50 mg t.i.d. to 100 mg t.i.d. However, since patients with low body weight may be at increased risk for elevated serum transaminases, only patients with body weight > 60 kg should be considered for dose titration above 50 mg t.i.d. (see PRECAUTIONS ). If no further reduction in postprandial glucose or glycosylated hemoglobin levels is observed with titration to 100 mg t.i.d., consideration should be given to lowering the dose. Once an effective and tolerated dosage is established, it should be maintained. Maximum Dosage The maximum recommended dose for patients ≤ 60 kg is 50 mg t.i.d. The maximum recommended dose for patients > 60 kg is 100 mg t.i.d. Patients Receiving Sulfonylureas or Insulin Sulfonylurea agents or insulin may cause hypoglycemia. Acarbose Tablets given in combination with a sulfonylurea or insulin will cause a further lowering of blood glucose and may increase the potential for hypoglycemia. If hypoglycemia occurs, appropriate adjustments in the dosage of these agents should be made.

ADVERSE REACTIONS Digestive Tract Gastrointestinal symptoms are the most common reactions to Acarbose Tablets. In U.S. placebo-controlled trials, the incidences of abdominal pain, diarrhea, and flatulence were 19%, 31%, and 74% respectively in 1255 patients treated with Acarbose Tablets 50-300 mg t.i.d., whereas the corresponding incidences were 9%, 12%, and 29% in 999 placebo-treated patients. In a one-year safety study, during which patients kept diaries of gastrointestinal symptoms, abdominal pain and diarrhea tended to return to pretreatment levels over time, and the frequency and intensity of flatulence tended to abate with time. The increased gastrointestinal tract symptoms in patients treated with Acarbose Tablets are a manifestation of the mechanism of action of Acarbose Tablets and are related to the presence of undigested carbohydrate in the lower GI tract. If the prescribed diet is not observed, the intestinal side effects may be intensified. If strongly distressing symptoms develop in spite of adherence to the diabetic diet prescribed, the doctor must be consulted and the dose temporarily or permanently reduced. Elevated Serum Transaminase Levels See PRECAUTIONS . Other Abnormal Laboratory Findings Small reductions in hematocrit occurred more often in Acarbose Tablets-treated patients than in placebo-treated patients but were not associated with reductions in hemoglobin. Low serum calcium and low plasma vitamin B 6 levels were associated with Acarbose Tablets therapy but are thought to be either spurious or of no clinical significance. Postmarketing Adverse Event Reports Additional adverse events reported from worldwide postmarketing experience include fulminant hepatitis with fatal outcome, hypersensitive skin reactions (for example, rash, erythema, exanthema and urticaria), edema, ileus/subileus, jaundice and/or hepatitis and associated liver damage, thrombocytopenia, and pneumatosis cystoides intestinalis (see PRECAUTIONS ). Pneumatosis Cystoides Intestinalis There have been rare postmarketing reports of pneumatosis cystoides intestinalis associated with the use of alpha-glucosidase inhibitors, including Acarbose Tablets. Pneumatosis cystoides intestinalis may present with symptoms of diarrhea, mucus discharge, rectal bleeding, and constipation. Complications may include pneumoperitoneum, volvulus, intestinal obstruction, intussusception, intestinal hemorrhage, and intestinal perforation. If pneumatosis cystoides intestinalis is suspected, discontinue Acarbose Tablets and perform the appropriate diagnostic imaging. Call your doctor for medical advice about side effects.
