albuterol carvedilol

Applies to: Combivent (albuterol / ipratropium) and carvedilol
Generally avoid

Beta-blockers may antagonize the effects of beta-2 adrenergic bronchodilators and precipitate acute, life-threatening bronchospasm in patients with asthma or other obstructive airway diseases. The mechanism involves increased airway resistance and reduced bronchodilation due to blockade of beta-2 adrenergic receptors. The interaction may also occur with ophthalmically applied beta-blockers, which are systemically absorbed and can produce clinically significant systemic effects even at low or undetectable plasma levels. Due to opposing effects on beta-2 adrenergic receptors, propranolol has been used in the treatment of albuterol overdose. Likewise, beta-2 adrenergic agonists may interfere with the pharmacologic effects of beta-blockers.

Management

Concomitant use of beta-2 adrenergic bronchodilators with beta-blockers, including ophthalmic formulations, should generally be avoided. If coadministration is required, a cardioselective beta-blocker (e.g., acebutolol, atenolol, betaxolol, bisoprolol, metoprolol, nebivolol) is usually preferred. Nevertheless, caution is advised and respiratory status should be closely monitored, as cardioselectivity is not absolute and larger doses of beta-1 selective agents may pose some of the same risks as nonselective agents. In general, nonselective beta-blockers are considered contraindicated in patients with obstructive airways disease.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

albuterol Caffeine

Applies to: Combivent (albuterol / ipratropium)
Monitor

Coadministration of two or more sympathomimetic or noradrenergic agents may increase the risk of nervousness, irritability, tachycardia, and/or increased blood pressure. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic and/or noradrenergic agents, including norepinephrine transporter inhibitors. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

Management

Caution is advised if two or more sympathomimetic or noradrenergic agents are coadministered. Pulse and blood pressure should be closely monitored. Consultation with individual product labeling, as well as relevant institutional protocols, may be advisable for further guidance.

Disease interactions

37 potential interactions Applies to: 29 conditions, including High Blood Pressure, High Cholesterol, Allergies, Asthma, and COPD.

Allergies

Major:

carvedilol

Carvedilol has a major potential interaction with Allergies.

The use of beta-adrenergic receptor blocking agents (aka beta-blockers) in patients with a history of allergic reactions or anaphylaxis may be associated with heightened reactivity to culprit allergens. The frequency and/or severity of attacks may be increased during beta-blocker therapy. In addition, these patients may be refractory to the usual doses of epinephrine used to treat acute hypersensitivity reactions and may require a beta-agonist such as isoproterenol.

Arrhythmia

Moderate:

Combivent

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.

Asthma

Major:

carvedilol

Carvedilol has a major potential interaction with Asthma.

Some beta-adrenergic receptor blocking agents (i.e., non-cardioselective beta-blockers) are contraindicated in patients with bronchial asthma or with a history of bronchial asthma, or severe chronic obstructive pulmonary disease. In general, beta-adrenergic receptor blocking agents should not be used in patients with bronchospastic diseases. Beta blockade may adversely affect pulmonary function by counteracting the bronchodilation produced by catecholamine stimulation of beta-2 receptors. If beta-blocker therapy is necessary in these patients, an agent with beta-1 selectivity (e.g., atenolol, metoprolol, betaxolol) is considered safer, but should be used with caution nonetheless. Cardioselectivity is not absolute and can be lost with larger doses.

Cardiogenic Shock

Major:

carvedilol

Carvedilol has a major potential interaction with Cardiogenic Shock.

The use of beta-adrenergic receptor blocking agents (aka beta-blockers) is contraindicated in patients with hypotension or cardiogenic shock. Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to further depress cardiac output and blood pressure, which can be detrimental in these patients.

Cerebrovascular Insufficiency

Major:

carvedilol

Carvedilol has a major potential interaction with Cerebrovascular Insufficiency.

The beta-adrenergic receptor blocking effects of carvedilol may precipitate or aggravate symptoms of arterial insufficiency in patients with peripheral vascular disease. Carvedilol may also attenuate catecholamine-mediated vasodilation during exercise by blocking beta-2 receptors in peripheral vessels. Therapy with carvedilol should be administered cautiously in patients with peripheral vascular disease. Close monitoring for progression of arterial obstruction is advised.

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Cerebrovascular Insufficiency.

Beta-adrenergic blocking agents (beta-blockers), should be used with caution in patients with cerebrovascular insufficiency because of their potential effects relative to blood pressure and pulse. If signs or symptoms suggesting reduced cerebral blood flow are observed, consideration should be given to discontinuing these agents.

COPD

Major:

carvedilol

Carvedilol has a major potential interaction with COPD.

Some beta-adrenergic receptor blocking agents (i.e., non-cardioselective beta-blockers) are contraindicated in patients with bronchial asthma or with a history of bronchial asthma, or severe chronic obstructive pulmonary disease. In general, beta-adrenergic receptor blocking agents should not be used in patients with bronchospastic diseases. Beta blockade may adversely affect pulmonary function by counteracting the bronchodilation produced by catecholamine stimulation of beta-2 receptors. If beta-blocker therapy is necessary in these patients, an agent with beta-1 selectivity (e.g., atenolol, metoprolol, betaxolol) is considered safer, but should be used with caution nonetheless. Cardioselectivity is not absolute and can be lost with larger doses.

Diabetes Mellitus

Moderate:

Combivent

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.

Glaucoma, Narrow Angle

Moderate:

Combivent

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).

Glaucoma/Intraocular Hypertension

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Glaucoma/Intraocular Hypertension.

Systemic beta-adrenergic receptor blocking agents (aka beta-blockers) may lower intraocular pressure. Therefore, patients with glaucoma or intraocular hypertension may require adjustments in their ophthalmic regimen following a dosing change or discontinuation of beta-blocker therapy.

Heart Block

Major:

carvedilol

Carvedilol has a major potential interaction with Heart Block.

The use of beta-adrenergic receptor blocking agents (aka beta-blockers) is contraindicated in patients with sinus bradyarrhythmia or heart block greater than the first degree (unless a functioning pacemaker is present). Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to exacerbate these conditions.

Heart Disease

Moderate:

Combivent

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.

Hemodialysis

Major:

carvedilol

Carvedilol has a major potential interaction with Hemodialysis.

Therapy with beta-adrenergic receptor blocking agents (aka beta-blockers) should be administered cautiously in patients requiring hemodialysis. When given after dialysis, hemodynamic stability should be established prior to drug administration to avoid marked falls in blood pressure. The hemodynamic status should be closely monitored before and after the dose.

High Blood Pressure

Moderate:

Combivent

The albuterol in Combivent 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. 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.

High Cholesterol

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with High Cholesterol.

Beta-adrenergic receptor blocking agents (aka beta-blockers) may alter serum lipid profiles. Increases in serum VLDL and LDL cholesterol and triglycerides, as well as decreases in HDL cholesterol, have been reported with some beta-blockers. Patients with preexisting hyperlipidemia may require closer monitoring during beta-blocker therapy, and adjustments made accordingly in their lipid-lowering regimen.

Hyperthyroidism

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Hyperthyroidism.

When beta-adrenergic receptor blocking agents (aka beta-blockers) are used to alleviate symptoms of hyperthyroidism such as tachycardia, anxiety, tremor and heat intolerance, abrupt withdrawal can exacerbate thyrotoxicosis or precipitate a thyroid storm. To minimize this risk, cessation of beta-blocker therapy, when necessary, should occur gradually with incrementally reduced dosages over a period of 1 to 2 weeks. Patients should be advised not to discontinue treatment without first consulting with the physician. Close monitoring is recommended during and after therapy withdrawal.

Moderate:

Combivent

The albuterol in Combivent 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. 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.

Hypokalemia

Moderate:

Combivent

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.

Hypotension

Major:

carvedilol

Carvedilol has a major potential interaction with Hypotension.

The use of beta-adrenergic receptor blocking agents (aka beta-blockers) is contraindicated in patients with hypotension or cardiogenic shock. Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to further depress cardiac output and blood pressure, which can be detrimental in these patients.

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Hypotension.

The use of carvedilol has rarely resulted in deterioration of renal function. Patients with low blood pressure (systolic BP < 100 mm Hg), ischemic heart disease and diffuse vascular disease, and/or underlying renal impairment may be at greater risk. In these patients, monitoring of renal function is recommended during dosage titration, and the dosing reduced or discontinued accordingly.

Ischemic Heart Disease

Major:

carvedilol

Carvedilol has a major potential interaction with Ischemic Heart Disease.

Heightened sensitivity to catecholamines may occur after prolonged use of beta-adrenergic receptor blocking agents (aka beta-blockers). Exacerbation of angina, myocardial infarction and ventricular arrhythmias have been reported in patients with coronary artery disease following abrupt withdrawal of therapy. Cessation of beta-blocker therapy, whenever necessary, should occur gradually with incrementally reduced dosages over a period of 1 to 2 weeks in patients with coronary insufficiency. Patients should be advised not to discontinue treatment without first consulting with the physician. In patients who experience an exacerbation of angina following discontinuation of beta-blocker therapy, the medication should generally be reinstituted, at least temporarily, along with other clinically appropriate measures.

Liver Disease

Major:

carvedilol

Carvedilol has a major potential interaction with Liver Disease.

The use of carvedilol is contraindicated in patients with severe hepatic impairment. Compared to healthy subjects, patients with severe liver impairment (cirrhosis) exhibit a 4- to 7-fold increase in carvedilol levels.

Major:

carvedilol

Carvedilol has a major potential interaction with Liver Disease.

Carvedilol is extensively metabolized by the liver. Patients with cirrhosis have demonstrated significantly higher plasma concentrations (approximately 4 to 7-fold) of carvedilol compared to healthy individuals. The use of carvedilol is contraindicated in patients with severe hepatic impairment.

Moderate:

Combivent

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.

Myasthenia Gravis

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Myasthenia Gravis.

Beta-adrenergic receptor blocking agents (aka beta-blockers) may potentiate muscle weakness consistent with certain myasthenic symptoms such as diplopia, ptosis, and generalized weakness. Several beta-blockers have been associated rarely with aggravation of muscle weakness in patients with preexisting myasthenia gravis or myasthenic symptoms. Use cautiously in patients with myasthenia gravis.

Peripheral Arterial Disease

Major:

carvedilol

Carvedilol has a major potential interaction with Peripheral Arterial Disease.

The beta-adrenergic receptor blocking effects of carvedilol may precipitate or aggravate symptoms of arterial insufficiency in patients with peripheral vascular disease. Carvedilol may also attenuate catecholamine-mediated vasodilation during exercise by blocking beta-2 receptors in peripheral vessels. Therapy with carvedilol should be administered cautiously in patients with peripheral vascular disease. Close monitoring for progression of arterial obstruction is advised.

Major:

carvedilol

Carvedilol has a major potential interaction with Peripheral Arterial Disease.

Due to their negative inotropic and chronotropic effects on the heart, beta-adrenergic receptor blocking agents (aka beta-blockers) reduce cardiac output and may precipitate or aggravate symptoms of arterial insufficiency in patients with peripheral vascular disease. In addition, the nonselective beta-blockers (e.g., propranolol, pindolol, timolol) may attenuate catecholamine-mediated vasodilation during exercise by blocking beta-2 receptors in peripheral vessels. Therapy with beta-blockers should be administered cautiously in patients with peripheral vascular disease. Close monitoring for progression of arterial obstruction is advised.

Pheochromocytoma

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Pheochromocytoma.

Administration of beta-blockers alone in the setting of pheochromocytoma has been associated with a paradoxical increase in blood pressure due to the attenuation of beta receptor-mediated vasodilatation in skeletal muscle. In patients with pheochromocytoma, an alpha-blocking agent should be initiated prior to the use of any beta-blocking agent. Caution should be taken in the administration of these agents to patients suspected of having pheochromocytoma.

Prinzmetal's Angina

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Prinzmetal's Angina.

Agents with non-selective beta-blocking activity may provoke chest pain in patients with Prinzmetal's variant angina. the use of non-selective beta blockers is not recommended in these patients. Caution should be taken in the administration of these agents to patients suspected of having Prinzmetal's variant angina.

Psoriasis

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Psoriasis.

The use of beta-blockers in psoriatic patients should be carefully weighed since the use of these agents may cause an aggravation in psoriasis.

Renal Dysfunction

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Renal Dysfunction.

The use of carvedilol has rarely resulted in deterioration of renal function. Patients with low blood pressure (systolic BP < 100 mm Hg), ischemic heart disease and diffuse vascular disease, and/or underlying renal impairment may be at greater risk. In these patients, monitoring of renal function is recommended during dosage titration, and the dosing reduced or discontinued accordingly.

Moderate:

Combivent

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

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

Moderate:

Combivent

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.

Seizures

Moderate:

Combivent

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.

Sinus Node Dysfunction

Major:

carvedilol

Carvedilol has a major potential interaction with Sinus Node Dysfunction.

The use of beta-adrenergic receptor blocking agents (aka beta-blockers) is contraindicated in patients with sinus bradyarrhythmia or heart block greater than the first degree (unless a functioning pacemaker is present). Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to exacerbate these conditions.

Tachyarrhythmia

Moderate:

carvedilol

Carvedilol has a moderate potential interaction with Tachyarrhythmia.

Beta-adrenergic blockade in patients with Wolff-Parkinson-White syndrome and tachycardia has been associated with severe bradycardia requiring treatment with a pacemaker. In one case, this result was reported after an initial dose of 5 mg propranolol. The use of beta-adrenergic receptor blocking agents (aka beta-blockers) should be administered cautiously in these patients.

Urinary Retention

Combivent

The ipratropium in Combivent has a moderate potential interaction with Urinary Retention.

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).
