Ipratropium

Paradoxical Bronchospasm In the clinical study of ipratropium bromide and albuterol sulfate inhalation solution, paradoxical bronchospasm was not observed. However, paradoxical bronchospasm has been observed with both inhaled ipratropium bromide and albuterol products and can be life-threatening. If this occurs, ipratropium bromide and albuterol sulfate inhalation solution should be discontinued immediately and alternative therapy instituted. Do Not Exceed Recommended Dose Fatalities have been reported in association with excessive use of inhaled products containing sympathomimetic amines and with the home use of nebulizers. Cardiovascular Effect Ipratropium bromide and albuterol sulfate inhalation solution, like other beta adrenergic agonists, can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms. Although such effects are uncommon for ipratropium bromide and albuterol sulfate inhalation solution at recommended doses, if they occur, the drug may need to be discontinued. In addition, beta agonists have been reported to produce ECG changes, such as flattening of the T-wave, prolongation of the QTc interval, and ST segment depression. The clinical significance of these findings is unknown. Therefore, ipratropium bromide and albuterol sulfate inhalation solution, like other sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension. Immediate Hypersensitivity Reactions Immediate hypersensitivity reactions to albuterol and/or ipratropium bromide may occur after the administration of ipratropium bromide and albuterol sulfate inhalation solution as demonstrated by rare cases of urticaria, angioedema, rash, pruritus, oropharyngeal edema, bronchospasm, and anaphylaxis.
