Interactions between Combivent and 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.

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.

The ipratropium in Combivent has a moderate potential interaction with Arrhythmia.

Cases of supraventricular tachycardia and atrial fibrillation have been reported with the use of inhaled anticholinergic agents in patients with COPD/Asthma. Care and monitoring of cardiac function is recommended when prescribing these agents to patients at risk.

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.

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.

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.

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.

The albuterol in Combivent has a moderate potential interaction with Diabetes Mellitus.

Adrenergic bronchodilators may cause increases in blood glucose concentrations. These effects are usually transient and slight, but may be significant with dosages higher than those normally recommended. Large doses of IV albuterol (not commercially available in the U.S.) and terbutaline sulfate have been reported to cause exacerbation of preexisting diabetes mellitus and ketoacidosis. Therapy with adrenergic bronchodilators should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate. Systemic adverse effects are minimized, but not abolished, by administration of these agents via oral inhalation.

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.

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.

The ipratropium in Combivent has a moderate potential interaction with Glaucoma, Narrow Angle.

Aclidinium, ipratropium, umeclidinium, and tiotropium are anticholinergic agents. Although systemic effects are uncommon due to the poor absorption of quaternary ammonium compounds from gastrointestinal and nasal mucosa, worsening of urinary retention or angle-closure glaucoma has been reported. Increased intraocular pressure and precipitation or exacerbation of angle-closure glaucoma may also occur due to inadvertent contact of the eye with aerosolized or nebulized drug. Accordingly, therapy with quaternary ammonium compounds should be administered cautiously in patients with urinary retention/obstruction or angle-closure glaucoma. Measures should be taken whenever possible to minimize ocular exposure to these drugs, such as keeping eyes closed during oral inhalation or use of a mouthpiece rather than face mask during nebulization. Patients should be advised to contact their physician if they experience urinary difficulty (especially in patients with prostatic hyperplasia or bladder neck obstruction); or signs and symptoms of angle-closure glaucoma (e.g., eye pain or discomfort; blurred vision; visual halos; colored images in association with red eyes from conjunctival congestion or corneal edema).

The albuterol in Combivent has a moderate potential interaction with Heart Disease.

Adrenergic bronchodilators can stimulate cardiovascular beta- 1 and beta- 2 receptors, resulting in adverse effects such as tachycardia, palpitation, peripheral vasodilation, blood pressure changes, and ECG changes (e.g., flattening of the T wave; prolongation of the QT interval; ST segment depression). Direct stimulation of cardiac tissues is mediated by beta- 1 receptors and thus less likely to occur with beta-2-selective agents such as albuterol. However, beta-2-selectivity is not absolute and can be lost with larger doses. High dosages of these agents have been associated with precipitation or aggravation of angina, myocardial ischemia, and cardiac arrhythmias. Therapy with adrenergic bronchodilators should be administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, and/or underlying cardiovascular disorders such as coronary insufficiency, cardiac arrhythmias, or hypertension. The recommended dosages should not be exceeded.

The albuterol in Combivent has a moderate potential interaction with High Blood Pressure.

The recommended dosages should not be exceeded.

The albuterol in Combivent has a moderate potential interaction with Hypokalemia.

Adrenergic bronchodilators may cause decreases in serum potassium concentrations, primarily when given by nebulization or intravenous administration. Although this effect is usually transient and does not require supplementation, clinically significant hypokalemia may occur in some patients, with the potential to induce cardiovascular adverse effects. The relevance of these observations to oral or oral aerosol/powder for inhalation therapy is unknown. Therapy with adrenergic bronchodilators should be administered cautiously in patients with or predisposed to hypokalemia.

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.

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.

The ipratropium in Combivent has a moderate potential interaction with Liver Disease.

Ipratropium has not been studied in patients with hepatic or renal insufficiency. Therapy with this agent should be used with caution in these patients.

glyBURIDE has a moderate potential interaction with Malnourishment.

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.

glyBURIDE has a moderate potential interaction with Panhypopituitarism.

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.

glyBURIDE has a major potential interaction with Renal Dysfunction.

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.

Ipratropium has not been studied in patients with hepatic or renal insufficiency. Therapy with this agent should be used with caution in these patients.

The albuterol in Combivent has a moderate potential interaction with Renal Dysfunction.

Levalbuterol is substantially excreted by the kidney, and the risk of toxic reactions may be greater in patients with impaired renal function. Care should be taken in dose selection in patients with renal impairment and it may be useful to monitor renal function.

The albuterol in Combivent has a moderate potential interaction with Seizures.

Adrenergic bronchodilators may cause CNS stimulation. Therapy with adrenergic bronchodilators should be administered cautiously in patients with seizure disorders. Systemic adverse effects are minimized, but not abolished, by administration of these agents via oral inhalation.
