(formoterol fumarate) Inhalation Solution, USP



Long-acting beta2-adrenergic agonists (LABA) increase the risk of asthma-related death. Data from a large placebo-controlled US study that compared the safety of another long-acting beta2-adrenergic ag-onist (salmeterol) or placebo added to usual asthma therapy showed an increase in asthma-related deaths in patients receiving salmeterol. This finding with salmeterol is considered a class effect of LABA, including formoterol, the active ingredient in PERFOROMIST In-halation Solution. The safety and efficacy of PERFOROMIST in pa-tients with asthma have not been established. All LABA, including PERFOROMIST, are contraindicated in patients with asthma with-out use of a long-term asthma control medication [see CONTRAINDICATIONS, WARNINGS AND PRECAUTIONS].


PERFOROMIST (formoterol fumarate) Inhalation Solution is supplied as 2 mL of formoterol fumarate inhalation solution packaged in a 2.5 mL single-use low-density polyethylene vial and overwrapped in a foil pouch. Each vial contains 2 mL of a clear, colorless solution composed of formoterol fumarate dihydrate, USP equivalent to 20 mcg of formoterol fumarate in an isotonic, sterile aqueous solution containing sodium chloride, pH adjusted to 5.0 with citric acid and sodium citrate.

The active component of PERFOROMIST Inhalation Solution is formoterol fumarate dihydrate, USP, a racemate. Formoterol fumarate dihydrate is a beta2-adrenergic bronchodilator. Its chemical name is (±)-2-hydroxy-5-[(1RS)-1-hydroxy-2-[[(1RS)-2-(4-methoxyphenyl)-1-methylethyl]-amino]ethyl]formanilide fumarate dihydrate; its structural formula is:

PERFOROMIST® (formoterol fumarate) Structural Formula Illustration

Formoterol fumarate dihydrate, USP has a molecular weight of 840.92 and its empirical formula is (C19H24N2O4)2•C4H4O4•2H2O. Formoterol fumarate dihydrate, USP is a white to yellowish crystalline powder, which is freely soluble in glacial acetic acid, soluble in methanol, sparingly soluble in ethanol and isopropanol, slightly soluble in water, and practically insoluble in acetone, ethyl acetate, and diethyl ether.

PERFOROMIST Inhalation Solution does not require dilution prior to administration by nebulization. Like all other nebulized treatments, the amount delivered to the lungs will depend on patient factors and the nebulization system used and its performance.

Using the PARI-LC Plus® nebulizer (with a facemask or mouthpiece) connected to a PRONEB® Ultra compressor under in vitro conditions, the mean delivered dose from the mouthpiece was approximately 7.3 mcg (37% of label claim). The mean nebulizer flow rate was 4 LPM and the nebulization time was 9 minutes. PERFOROMIST Inhalation Solution should be administered from a standard jet nebulizer at adequate flow rates via a facemask or mouthpiece.
