फॉर्मोटेरोल और सैल्मेटेरोल का इंटरैक्शन

Excessive Use of SEREVENT DISKUS and Use with Other Long-acting Beta 2 -agonists SEREVENT DISKUS should not be used more often than recommended, at higher doses than recommended, or in conjunction with other medicines containing LABA, as an overdose may result.

Patients using SEREVENT DISKUS should not use another medicine containing a LABA (e.g., formoterol fumarate, arformoterol tartrate, indacaterol) for any reason.

• A 28-week, placebo-controlled US study comparing the safety of another LABA (salmeterol) with placebo, each added to usual asthma therapy, showed an increase in asthma-related deaths in patients receiving salmeterol (13/13,176 in patients treated with salmeterol vs. 3/13,179 in patients treated with placebo; RR 4.37, 95% CI 1.25, 15.34).

Excessive Use and Use with Other Long-Acting Beta 2 -Agonists As with other inhaled beta 2 -adrenergic drugs, formoterol fumarate inhalation solution should not be used more often, at higher doses than recommended, or in conjunction with other medications containing long-acting beta 2 -agonists, as an overdose may result.

Paradoxical Bronchospasm As with other inhaled beta 2 -agonists, formoterol fumarate inhalation solution can produce paradoxical bronchospasm that may be life-threatening.

Cardiovascular Effects Formoterol fumarate inhalation solution, like other beta 2 -agonists, can produce a clinically significant cardiovascular effect in some patients as measured by increases in pulse rate, systolic and/or diastolic blood pressure, and/or symptoms.

Therefore, formoterol fumarate inhalation solution, like other sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.
