फॉर्मोटेरोल और फिनाइलएफ्रिन का इंटरैक्शन

The increased risk of asthma-related death is considered a class effect of the long-acting beta 2 -adrenergic agonists, including formoterol fumarate inhalation solution.

Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs.

• Use with caution in patients with cardiovascular or convulsive disorders, thyrotoxicosis, or with sensitivity to sympathomimetic drugs.

• Use of long-acting beta 2 -adrenergic agonists (LABA) as monotherapy [without inhaled corticosteroids (ICS)] for asthma is associated with an increased risk of asthma-related death.

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.

Pressor Effect with Concomitant Oxytocic Drugs Oxytocic drugs potentiate the increasing blood pressure effect of sympathomimetic pressor amines including BIORPHEN [see Drug Interactions (7.1) ] , with the potential for hemorrhagic stroke.
