Can you take Bitolterol with Dofetilide?

Dofetilide has a moderate potential interaction with Dehydration.

Dofetilide should be avoided in patients that experience symptoms that may be associated with altered electrolyte balance, such as excessive or prolonged diarrhea, sweating, or vomiting or loss of appetite or thirst, these conditions should immediately be reported to their health care provider.

Bitolterol 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.

Dofetilide has a moderate potential interaction with Diarrhea.

Dofetilide should be avoided in patients that experience symptoms that may be associated with altered electrolyte balance, such as excessive or prolonged diarrhea, sweating, or vomiting or loss of appetite or thirst, these conditions should immediately be reported to their health care provider.

Dofetilide has a moderate potential interaction with Electrolyte Abnormalities.

Dofetilide should be avoided in patients that experience symptoms that may be associated with altered electrolyte balance, such as excessive or prolonged diarrhea, sweating, or vomiting or loss of appetite or thirst, these conditions should immediately be reported to their health care provider.

Bitolterol 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.

Bitolterol has a moderate potential interaction with High Blood Pressure.

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.

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.

Bitolterol has a moderate potential interaction with Hyperthyroidism.

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.

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.

Bitolterol 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.

Dofetilide has a moderate potential interaction with Hypokalemia.

Serum potassium should be maintained within the normal range before dofetilide treatment is initiated and should be maintained within the normal range while the patient remains on dofetilide therapy. In clinical trials, potassium levels were generally maintained above 3.6 to 4.0 mEq/L. Exercise care when using this agent in patients with hypokalemia.

Dofetilide has a moderate potential interaction with Liver Disease.

Dofetilide has not been studied in patients with severe hepatic impairment. Dofetilide should be used with particular caution in these patients.

Dofetilide has a major potential interaction with Long QT Syndrome.

Dofetilide is contraindicated in patients with congenital or acquired long QT syndromes. Dofetilide should not be used in patients with a baseline QT interval of QTc >440 msec (500 msec in patients with ventricular conduction abnormalities).

Dofetilide has a major potential interaction with Renal Dysfunction.

Dofetilide is contraindicated in patients with severe renal impairment (calculated creatinine clearance <20 mL/min). The risk of QT interval prolongation, Torsade de Pointes, and ventricular arrhythmias is directly related to dofetilide plasma concentration. A reduced creatinine clearance will increase dofetilide plasma concentration. In patients with mild and moderate renal impairment, the risk of arrhythmias can be reduced by controlling the plasma concentration through adjustment of the initial dofetilide dose according to creatinine clearance. Patients undergoing dialysis were not included in clinical studies, and appropriate dosing recommendations for these patients are unknown. There is no information about the effectiveness of hemodialysis in removing dofetilide from plasma.

Bitolterol 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.

Dofetilide has a moderate potential interaction with Vomiting.

Dofetilide should be avoided in patients that experience symptoms that may be associated with altered electrolyte balance, such as excessive or prolonged diarrhea, sweating, or vomiting or loss of appetite or thirst, these conditions should immediately be reported to their health care provider.
