Drug interactions
Moderate drug interactions
Moderate:
nadolol calcium carbonate
Applies to: nadolol and Rolaids Regular Strength (calcium carbonate / magnesium hydroxide)
Adjust dosing interval
Concurrent administration with calcium salts may decrease the oral bioavailability of atenolol and possibly other beta-blockers. The exact mechanism of interaction is unknown. In six healthy subjects, calcium 500 mg (as lactate, carbonate, and gluconate) reduced the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of atenolol (100 mg) by 51% and 32%, respectively. The elimination half-life increased by 44%. Twelve hours after the combination, beta-blocking activity (as indicated by inhibition of exercise tachycardia) was reduced compared to that with atenolol alone. However, during a 4-week treatment in six hypertensive patients, there was no difference in blood pressure values between treatments. The investigators suggest that prolongation of the elimination half-life induced by calcium coadministration may have led to atenolol cumulation during long-term dosing, which compensated for the reduced bioavailability.
Management
It may help to separate the administration times of beta-blockers and calcium products by at least 2 hours. Patients should be monitored for potentially diminished beta-blocking effects following the addition of calcium therapy.

nadolol magnesium hydroxide
Applies to: nadolol and Rolaids Regular Strength (calcium carbonate / magnesium hydroxide)
Concurrent administration with aluminum and magnesium antacids has been shown to decrease the oral bioavailability of certain beta-blockers, although data are conflicting. The exact mechanism of interaction is unknown but may involve cation binding of beta-blockers or a reduction in the dissolution rate due to increased gastric pH. In six healthy volunteers, concomitant administration of a single dose of antacid (magnesium hydroxide-aluminum oxide 1200 mg-1800 mg) reduced the peak plasma concentration (Cmax), area under the concentration-time curve (AUC) and 24-hour urinary excretion of sotalol (160 mg) by 27%, 21% and 9%, respectively, while administration of the antacid 2 hours after the sotalol dose produced no change. Pharmacodynamic data suggest that the negative chronotropic effect of sotalol was also reduced up to 4 hours after administration of the combination, although the lack of a placebo control might have confounded the results. In another study, concomitant administration of an aluminum hydroxide antacid in six healthy volunteers decreased atenolol (100 mg) Cmax and AUC by 37% and 33%, respectively. However, the Cmax and AUC of metoprolol (100 mg) in the same group was increased 25% and 11%, respectively, by administration of the antacid. Two other studies with aluminum hydroxide failed to find a significant effect on pharmacokinetics or pharmacodynamics of atenolol and propranolol. Based on available data, the clinical significance of this potential interaction is difficult to determine. As a precaution, patients may want to consider separating the administration times of beta-blockers and antacids or other aluminum- or magnesium-containing products by at least 2 hours.

Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
nadolol Food/Lifestyle
Applies to: nadolol
Generally avoid
Coadministration with green tea may significantly decrease the plasma concentrations of nadolol. The mechanism of interaction has not been established, but may involve inhibition of OATP1A2-mediated uptake of nadolol in the intestine by catechins in green tea. In a study with ten healthy volunteers, administration of a single 30 mg oral dose of nadolol following repeated consumption of green tea (700 mL/day for 14 days) resulted in decreases of 85% in nadolol peak plasma concentration (Cmax) and systemic exposure (AUC) compared to administration with water. The renal clearance of nadolol was not altered. Green tea also markedly reduced the effects of nadolol on systolic blood pressure.
Management
Based on available data, patients should be advised to limit their consumption of green tea and green tea extracts during treatment with nadolol.

Moderate:
calcium carbonate Food/Lifestyle
Applies to: Rolaids Regular Strength (calcium carbonate / magnesium hydroxide)
Adjust dosing interval
Administration with food may increase the absorption of calcium. However, foods high in oxalic acid (spinach or rhubarb), or phytic acid (bran and whole grains) may decrease calcium absorption.
Management
Calcium may be administered with food to increase absorption. Consider withholding calcium administration for at least 2 hours before or after consuming foods high in oxalic acid or phytic acid.

Moderate:
nadolol Alcohol (Ethanol)
Applies to: nadolol
Monitor
Certain psychotherapeutic and other CNS-active agents may have blood pressure-lowering effects and may cause dizziness, orthostatic hypotension, or syncope. These effects may be more likely during treatment initiation, dose escalation, or treatment restart. Coadministration with antihypertensives or other agents with blood pressure-lowering properties, particularly vasodilators and alpha-adrenergic blockers, may result in additive hypotensive or orthostatic effects.
Management
Monitor blood pressure and clinical response during concomitant use, especially when starting or increasing the dose of either agent. Patients should be advised to rise slowly from a sitting or lying position and to report dizziness, lightheadedness, fainting, orthostasis, palpitations, or troublesome changes in pulse or heart rate. Patients should be cautioned that alcohol may enhance blood pressure-lowering effects during concomitant use with antihypertensives or other agents with hypotensive properties. Patients should avoid driving or operating hazardous machinery until they know how the medications affect them.

Disease interactions
31 potential interactions Applies to: 29 conditions, including High Cholesterol, Allergies, Heart Failure, Asthma, and COPD.
Achlorhydria
Major:
Rolaids Regular Strength
The calcium carbonate in Rolaids Regular Strength has a major potential interaction with Achlorhydria.
Calcium is absorbed from the intestinal tract by active transport and passive diffusion. Malabsorption syndromes (celiac disease, GI resection), deficiency of vitamin D, parathyroid hormone, or calcitonin, or an alkaline gastric pH (achlorhydria, carbonate or phosphate salts) can decrease the absorption of oral formulations of calcium. Calcium is available in oral and parenteral formulations.
Allergies
Major:
nadolol
Nadolol 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
Major:
Rolaids Regular Strength
The calcium carbonate in Rolaids Regular Strength has a major potential interaction with Arrhythmia.
Calcium is involved in cardiac muscle contraction and electrical impulse conduction. Therapy with calcium salt formulations (particularly IV) should be administered cautiously to patients with cardiac disease. Patients receiving cardiac glycosides and concomitant IV calcium may experience arrhythmias. Therapy with IV calcium should be administered slowly and at reduced dosages in patients with cardiac disease.
Asthma
Major:
nadolol
Nadolol 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:
nadolol
Nadolol 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
Moderate:
nadolol
Nadolol 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:
nadolol
Nadolol 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
Major:
nadolol
Nadolol has a major potential interaction with Diabetes Mellitus.
Beta-adrenergic receptor blocking agents (aka beta-blockers) may mask symptoms of hypoglycemia such as tremors, tachycardia and blood pressure changes. In addition, the nonselective beta-blockers (e.g., propranolol, pindolol, timolol) may inhibit catecholamine-mediated glycogenolysis, thereby potentiating insulin-induced hypoglycemia and delaying the recovery of normal blood glucose levels. Since cardioselectivity is not absolute, larger doses of beta-1 selective agents may demonstrate these effects as well. Therapy with beta-blockers should be administered cautiously in patients with diabetes or predisposed to spontaneous hypoglycemia.
Gastrointestinal Obstruction
Major:
Rolaids Regular Strength
The magnesium hydroxide in Rolaids Regular Strength has a major potential interaction with Gastrointestinal Obstruction.
The use of laxatives is contraindicated in patients with intestinal obstruction disorders. Patients with intestinal obstruction disorders may need their underlying condition treated to correct the constipation. Some laxatives require reduction in the colon to their active form to be effective which may be a problem in patients with intestinal obstruction.
Glaucoma/Intraocular Hypertension
Moderate:
nadolol
Nadolol 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:
nadolol
Nadolol 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 Failure
Major:
nadolol
Nadolol has a major potential interaction with Heart Failure.
Beta-adrenergic receptor blocking agents (aka beta-blockers) in general should not be used in patients with overt congestive heart failure (CHF). Sympathetic stimulation may be important in maintaining the hemodynamic function in these patients, thus beta-blockade can worsen the heart failure. However, therapy with beta-blockers may be beneficial and can be administered cautiously in some CHF patients provided they are well compensated and receiving digitalis, diuretics, an ACE inhibitor, and/or nitrates. Carvedilol, specifically, is indicated for use with these agents in the treatment of mild to severe heart failure of ischemic or cardiomyopathic origin. There is also increasing evidence that the addition of a beta-blocker to standard therapy can improve morbidity and mortality in patients with advanced heart failure, although it is uncertain whether effectiveness varies significantly with the different agents. Data from one meta-analysis study suggest a greater reduction of mortality risk for nonselective beta-blockers than for beta-1 selective agents.
Hemodialysis
Major:
nadolol
Nadolol 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 Cholesterol
Moderate:
nadolol
Nadolol 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:
nadolol
Nadolol 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.
Hypotension
Major:
nadolol
Nadolol 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.
Inflammatory Bowel Disease
Major:
Rolaids Regular Strength
The magnesium hydroxide in Rolaids Regular Strength has a major potential interaction with Inflammatory Bowel Disease.
The use of laxatives is contraindicated in patients with inflammatory bowel disease. Patients with inflammatory bowel disease may experience colonic perforation with use of stimulant laxatives.
Ischemic Heart Disease
Major:
nadolol
Nadolol 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.
Malabsorption Syndrome
Major:
Rolaids Regular Strength
The calcium carbonate in Rolaids Regular Strength has a major potential interaction with Malabsorption Syndrome.
Calcium is absorbed from the intestinal tract by active transport and passive diffusion. Malabsorption syndromes (celiac disease, GI resection), deficiency of vitamin D, parathyroid hormone, or calcitonin, or an alkaline gastric pH (achlorhydria, carbonate or phosphate salts) can decrease the absorption of oral formulations of calcium. Calcium is available in oral and parenteral formulations.
Myasthenia Gravis
Moderate:
nadolol
Nadolol 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:
nadolol
Nadolol 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:
nadolol
Nadolol 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.
Phosphate Imbalance
Major:
Rolaids Regular Strength
The calcium carbonate in Rolaids Regular Strength has a major potential interaction with Phosphate Imbalance.
Elevated serum concentrations of calcium and phosphate can exceed the solubility level and result in calcium- phosphate precipitates that deposit in vascular and renal systems as well as other soft tissues of the body. Therapy with calcium should be administered with extreme caution in patients with hyperphosphatemia (hypoparathyroidism or severe renal impairment). Administration of oral calcium acetate or calcium carbonate, in addition to providing calcium, complexes phosphates within the GI tract. These complexes are eliminated in the feces. Clinical monitoring of serum calcium and phosphate concentrations is necessary.
Prinzmetal's Angina
Moderate:
nadolol
Nadolol 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:
nadolol
Nadolol 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
Major:
nadolol
Nadolol has a major potential interaction with Renal Dysfunction.
Nadolol is primarily eliminated by the kidney. Patients with renal impairment may be at greater risk for adverse effects from nadolol due to decreased drug clearance. Therapy with nadolol should be administered cautiously in patients with renal impairment. Dosage adjustments (i.e. prolongation of dosing interval) are recommended for patients with moderate to severe renal dysfunction (CrCl <= 50 mL/min).
Major:
Rolaids Regular Strength
The magnesium hydroxide in Rolaids Regular Strength has a major potential interaction with Renal Dysfunction.
Magnesium is eliminated by the kidney. The serum concentration of magnesium is increased in patients with renal impairment. Magnesium toxicity includes CNS depression, muscular paralysis, respiratory depression, hypotension and prolonged cardiac conduction time. Disappearance of the patellar reflex is a useful clinical sign of magnesium intoxication. Therapy with magnesium should be administered cautiously and dosages should be modified in patients with compromised renal function. Clinical monitoring of serum magnesium levels is recommended.
Major:
Rolaids Regular Strength
The calcium carbonate in Rolaids Regular Strength has a major potential interaction with Renal Dysfunction.
Absorption of oral calcium formulations may be altered and elimination of calcium by the kidney decreased with renal impairment. Hyperphosphatemia occurs during renal failure. Calcium acetate or calcium carbonate, in addition to providing calcium, complexes phosphates within the GI tract. Calcium carbonate can partially correct metabolic acidosis associated with chronic renal failure. Clinical monitoring of renal function and serum calcium and phosphate concentrations is necessary.
Sarcoidosis
Major:
Rolaids Regular Strength
The calcium carbonate in Rolaids Regular Strength has a major potential interaction with Sarcoidosis.
Hypercalciuria, with or without hypercalcemia, may occasionally occur in patients with sarcoidosis. Elevated calcium levels may result from increased intestinal absorption of calcium, which is related to the extrarenal production of vitamin D by mononuclear phagocytes present within the sarcoid granuloma. Therapy with calcium salts should be administered cautiously and only if necessary in patients with sarcoidosis.
Sinus Node Dysfunction
Major:
nadolol
Nadolol 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:
nadolol
Nadolol 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.
