Glycopyrronium Bromide + Formoterol Fumarate interactions

Food & lifestyle

• alcohol

  Moderate

  Synergy

  Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous. In addition, the potential for abuse may be increased with the combination. The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system.

  What to do: Alcohol should generally be avoided during therapy with anticholinergic agents. Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.

Conditions

Conditions in which Glycopyrronium Bromide + Formoterol Fumarate needs care, as documented in this source.

• Arrhythmias, Cardiac

  Major

  Patients with tachycardia should be supervised closely during treatment with anticholinergic agents. Tachycardia is produced by blocking normal vagal inhibition of the SA node. Paradoxically, bradycardia may occur due to central vagal stimulation which may occur prior to peripheral cholinergic blockade.

• Diabetic Neuropathies

  Major

  Agents with anticholinergic activity can exacerbate many of the manifestations of autonomic neuropathy, including tachycardia, anhidrosis, bladder atony, obstipation, dry mouth and eyes, cycloplegia and blurring of vision, and sexual impotence in males. Therapy with antimuscarinic agents and higher dosages of antispasmodic agents (e.g., dicyclomine or oxybutynin) should be administered cautiously in patients with autonomic neuropathy.

• Dysentery

  Major

  The use of drugs with antiperistaltic activity (primarily antidiarrheal and antimuscarinic agents, but also antispasmodic agents such as dicyclomine or oxybutynin at high dosages) is contraindicated in patients with diarrhea due to pseudomembranous enterocolitis or enterotoxin-producing bacteria. These drugs may prolong and/or worsen diarrhea associated with organisms that invade the intestinal mucosa, such as toxigenic E. coli, Salmonella and Shigella, and pseudomembranous colitis due to broad-spectrum antibiotics. Other symptoms and complications such as fever, shedding of organisms and extraintestinal illness may also be increased or prolonged. In general, because antiperistaltic agents decrease gastrointestinal motility, they may delay the excretion of infective gastroenteric organisms or toxins and should be used cautiously in patients with any infectious diarrhea, particularly if accompanied by high fever or pus or blood in the stool. Some cough and cold and other combination products may occasionally include antimuscarinic agents for their drying effects and may, therefore, require careful selection when necessary.

• Glaucoma

  Major

  Anticholinergic agents are contraindicated in patients with primary glaucoma, a tendency toward glaucoma (narrow anterior chamber angle), or adhesions (synechiae) between the iris and lens, as well as for the elderly and others in whom undiagnosed glaucoma or excessive pressure in the eye may be present. Because anticholinergics cause mydriasis, they may exacerbate these conditions.

• Intestinal Obstruction

  Major

  Anticholinergics are contraindicated in patients with obstructive diseases such as achalasia, esophageal stricture or stenosis, pyloroduodenal stenosis, stenosing peptic ulcer, pyloric obstruction, and paralytic ileus. Anticholinergics may further suppress intestinal motility with resultant precipitation or aggravation of toxic megacolon.

• Tardive Dyskinesia

  Major

  Anticholinergic agents and agents with secondary anticholinergic activity may aggravate tardive dyskinesia or induce previously suppressed symptoms. Therapy with these agents should be avoided, if possible, or administered cautiously in patients with preexisting tardive dyskinesia, particularly in the elderly. If tardive dyskinesia symptoms develop or worsen during treatment with an anticholinergic agent, prompt withdrawal of therapy will provide better chances of improving the condition.

• Urinary Bladder Neck Obstruction

  Major

  In general, the use of anticholinergic agents is contraindicated in patients with urinary retention and bladder neck obstruction caused by prostatic hypertrophy. Dysuria may occur and may require catheterization. Also, anticholinergic drugs may aggravate partial obstructive uropathy. Caution is advised even when using agents with mild to moderate anticholinergic activity, particularly in elderly patients.

• Cardiovascular Diseases

  Moderate

  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.

• Diabetes Mellitus

  Moderate

  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.

• Hypokalemia

  Moderate

  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.

• Psychotic Disorders

  Moderate

  Toxic psychosis manifested as confusion, disorientation, agitation, excitation, memory impairment, delusions and hallucinations may develop at toxic and therapeutic dosages of antimuscarinic agents. Therapy with these agents should be administered cautiously in patients with mental disorders receiving antimuscarinic agents for control of drug-induced extrapyramidal effects, especially at the beginning of therapy or during dosage adjustment. Psychiatric deterioration and psychotic flare-ups have also been reported following withdrawal of therapy. Symptoms include delusions, hallucinations, aggression or violent behavior, and suicidal tendencies. In high dosages, antimuscarinic agents may sometimes produce euphorigenic effects. For this reason, it can be a drug of abuse.

• Seizures

  Moderate

  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.
