Drug interactions
Moderate drug interactions
Moderate:
glyBURIDE pretomanid
Applies to: glyburide and pretomanid
Monitor
Coadministration with pretomanid may increase the plasma concentrations and the risk of adverse effects of drugs that are substrates of breast cancer resistance protein (BCRP), organic anion-transporting polypeptide (OATP1B3), and/or P-glycoprotein (P-gp). The proposed mechanism, based on in vitro data, is decreased clearance due to pretomanid-mediated inhibition of BCRP, OATP1B3, and/or P-gp. The clinical significance is unknown as data are limited and conflicting.
Management
Until more information is available, the manufacturers of pretomanid recommend that clinicians should be aware of the potential for enhanced pharmacologic effects with drugs that are substrates of BCRP, OATP1B3, and/or Pg-p, particularly those with a narrow therapeutic range, when pretomanid is coadministered. Dosage adjustments as well as clinical and laboratory monitoring of the BCRP, OATP1B3, and/or P-gp substrate drug should be considered whenever pretomanid is added to or withdrawn from therapy with these drugs. Patients should be monitored for the development of adverse effects.

Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
glyBURIDE Food/Lifestyle
Applies to: glyburide
Generally avoid
Alcohol may cause hypoglycemia or hyperglycemia in patients with diabetes. Hypoglycemia most frequently occurs during acute consumption of alcohol. Even modest amounts can lower blood sugar significantly, especially when the alcohol is ingested on an empty stomach or following exercise. The mechanism involves inhibition of both gluconeogenesis as well as the counter-regulatory response to hypoglycemia. Episodes of hypoglycemia may last for 8 to 12 hours after ethanol ingestion. By contrast, chronic alcohol abuse can cause impaired glucose tolerance and hyperglycemia. Moderate alcohol consumption generally does not affect blood glucose levels in patients with well controlled diabetes. A disulfiram-like reaction (e.g., flushing, headache, and nausea) to alcohol has been reported frequently with the use of chlorpropamide and very rarely with other sulfonylureas.
Management
Patients with diabetes should avoid consuming alcohol if their blood glucose is not well controlled, or if they have hypertriglyceridemia, neuropathy, or pancreatitis. Patients with well controlled diabetes should limit their alcohol intake to one drink daily for women and two drinks daily for men (1 drink = 5 oz wine, 12 oz beer, or 1.5 oz distilled spirits) in conjunction with their normal meal plan. Alcohol should not be consumed on an empty stomach or following exercise.

pretomanid Food/Lifestyle
Applies to: pretomanid
Generally avoid
Coadministration with alcohol may increase the risk of hepatotoxicity associated with the use of combination drug regimens that include pretomanid.
Adjust dosing interval
Food enhances the oral bioavailability of pretomanid. The mechanism has not been reported. Compared with the fasted state, oral administration of pretomanid with a high-fat, high-calorie meal (approximately 150, 250, and 500 to 600 calories from protein, carbohydrate, and fat, respectively) increased mean systemic exposure (AUC) and peak plasma concentration (Cmax) of pretomanid by 88% and 76%, respectively.
Management
Patients should avoid alcohol use during treatment with pretomanid. In addition, to ensure maximal oral absorption, pretomanid should be administered with food. Tablets should be swallowed whole.

17 potential interactions Applies to: 15 conditions, including Diabetes, Type 1, Adrenal Insufficiency, Liver Disease, Hyponatremia, and Dehydration.
Adrenal Insufficiency
Moderate:
glyburide
glyBURIDE has a moderate potential interaction with Adrenal Insufficiency.
Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.
Alcoholism
Moderate:
pretomanid
Pretomanid has a moderate potential interaction with Alcoholism.
The effect of liver dysfunction on the safety, effectiveness, and pharmacokinetics of pretomanid has not been established. The combination regimen of pretomanid, bedaquiline, and linezolid has been associated with hepatic adverse reactions; alcohol and hepatotoxic agents should be avoided during pretomanid treatment, especially in patients with liver dysfunction. It is recommended to monitor signs and symptoms of hepatotoxicity and laboratory tests (ALT, AST, alkaline phosphatase, and bilirubin) at least at baseline, at 2 weeks, and then monthly while on treatment and as needed. If evidence of new or worsening liver dysfunction occurs, it is recommended to test for viral hepatitides and discontinue other hepatotoxic medications.
Anorexia/Feeding Problems
Moderate:
glyburide
glyBURIDE has a moderate potential interaction with Anorexia/Feeding Problems.
Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.
Autonomic Neuropathy
Moderate:
glyburide
glyBURIDE has a moderate potential interaction with Autonomic Neuropathy.
Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.
Cardiovascular Conditions and Disorders
Major:
glyburide
glyBURIDE has a major potential interaction with Cardiovascular Conditions and Disorders.
The use of oral hypoglycemic agents may be associated with an increased risk of cardiovascular mortality compared to treatment with diet alone or diet with insulin. This warning is based on the University Group Diabetes Program (UGDP) study, a long-term prospective clinical trial designed to evaluate the effectiveness of glucose-lowering drugs in preventing or delaying vascular complications in patients with non-insulin-dependent diabetes. Patients treated with diet plus a fixed dosage of either tolbutamide (a sulfonylurea) or phenformin (a biguanide) for 5 to 8 years had a cardiovascular mortality rate approximately 2.5 times that of patients treated with diet alone, resulting in discontinuation of both these treatments in the study. Despite controversy regarding interpretation of these results, clinicians and patients should be aware of the potential risk when making treatment decisions for diabetes, particularly in the presence of underlying cardiovascular disease. Data are not available for other sulfonylureas or biguanides, nor for hypoglycemic agents belonging to other classes. However, given the similarities in chemical structure and/or mode of action, the same caution should be applied.
Dehydration
Moderate:
glyburide
glyBURIDE has a moderate potential interaction with Dehydration.
Treatment with sulfonylureas may cause hyponatremia, in patients who are on other medications or have medical conditions known to cause hyponatremia or increase release of antidiuretic hormone. The syndrome of inappropriate antidiuretic hormone (SIADH) secretion has been reported with certain sulfonylureas and these drugs may augment the peripheral (antidiuretic) action of ADH and/or increase release of ADH. Caution should be used when treating patients with hyponatremia or at greater risk of developing hyponatremia such as elderly patients, patients taking diuretics or those who are volume-depleted.
Diabetes, Type 1
Major:
glyburide
glyBURIDE has a major potential interaction with Diabetes, Type 1.
The use of some sulfonylurea agents is contraindicated for the treatment of patients with diabetic ketoacidosis, with or without coma. In addition, these agents should not be used as sole therapy in patients with type I diabetes mellitus.
Diabetic Ketoacidosis
Major:
glyburide
glyBURIDE has a major potential interaction with Diabetic Ketoacidosis.
The use of some sulfonylurea agents is contraindicated for the treatment of patients with diabetic ketoacidosis, with or without coma. In addition, these agents should not be used as sole therapy in patients with type I diabetes mellitus.
G-6-PD Deficiency
Moderate:
glyburide
glyBURIDE has a moderate potential interaction with G-6-PD Deficiency.
Sulfonylureas can cause hemolytic anemia in patients with glucose 6-phosphate dehydrogenase (G6PD) deficiency. Therapy with these agents should be used with caution in patients with G6PD deficiency and consider the use of a non-sulfonylurea alternative. There have been postmarketing reports of hemolytic anemia in patients receiving these drugs who did not have known G6PD deficiency.
Hyponatremia
Moderate:
glyburide
glyBURIDE has a moderate potential interaction with Hyponatremia.
Treatment with sulfonylureas may cause hyponatremia, in patients who are on other medications or have medical conditions known to cause hyponatremia or increase release of antidiuretic hormone. The syndrome of inappropriate antidiuretic hormone (SIADH) secretion has been reported with certain sulfonylureas and these drugs may augment the peripheral (antidiuretic) action of ADH and/or increase release of ADH. Caution should be used when treating patients with hyponatremia or at greater risk of developing hyponatremia such as elderly patients, patients taking diuretics or those who are volume-depleted.
Liver Disease
Major:
glyburide
glyBURIDE has a major potential interaction with Liver Disease.
Sulfonylureas are metabolized in the liver, and their metabolites (some with pharmacologic activity) are excreted in the urine and feces. Patients with impaired liver and/or renal function treated with sulfonylureas may be exposed to higher serum drug concentrations, which can increase the potential for severe hypoglycemic episodes induced by these agents. In the presence of hepatic impairment, gluconeogenic capacity may also be diminished, further compounding the risk. Therapy with sulfonylureas should be administered cautiously in patients with liver and/or renal disease. Reduced dosages and longer intervals between dosage adjustments may be required. Hypoglycemia, if it occurs during treatment, may be prolonged in these patients because of slowed metabolism and/or excretion of the drugs.
Moderate:
pretomanid
Pretomanid has a moderate potential interaction with Liver Disease.
The effect of liver dysfunction on the safety, effectiveness, and pharmacokinetics of pretomanid has not been established. The combination regimen of pretomanid, bedaquiline, and linezolid has been associated with hepatic adverse reactions; alcohol and hepatotoxic agents should be avoided during pretomanid treatment, especially in patients with liver dysfunction. It is recommended to monitor signs and symptoms of hepatotoxicity and laboratory tests (ALT, AST, alkaline phosphatase, and bilirubin) at least at baseline, at 2 weeks, and then monthly while on treatment and as needed. If evidence of new or worsening liver dysfunction occurs, it is recommended to test for viral hepatitides and discontinue other hepatotoxic medications.
Malnourishment
Moderate:
