arformoterol tartrate - Generic Medications

Arformoterol tartrate inhalation solution is a sterile, clear, colorless, aqueous solution of the tartrate salt of arformoterol, the (R,R)-enantiomer of formoterol. Arformoterol is a selective beta 2 -adrenergic bronchodilator. The chemical name for arformoterol tartrate is formamide, N-[2-hydroxy-5-[(lR)-1-hydroxy-2-[[(lR)-2-(4-methoxyphenyl)-1- methylethyl]amino]ethyl]phenyl]-, (2R,3R)-2,3-dihydroxybutanedioate (1: 1 salt), and its established structural formula is as follows: The molecular weight of arformoterol tartrate is 494.5 g/mol, and its empirical formula is C 19 H 24 N 2 O 4 •C 4 H 6 O 6 (1:1 salt). It is a white to off-white powder that is freely soluble in dimethyl sulfoxide, sparingly soluble in water, slightly soluble in methanol, practically insoluble in acetonitrile. Arformoterol tartrate is the United States Adopted Name (USAN) for (R,R)-formoterol L-tartrate. Arformoterol tartrate inhalation solution is supplied as 2 mL of arformoterol tartrate solution packaged in 2.1 mL unit-dose, low-density polyethylene (LDPE) unit-dose vials. Each unit-dose vial contains 15 mcg of arformoterol (equivalent to 22 mcg of arformoterol tartrate) in a sterile, isotonic saline solution, pH-adjusted to 5.0 with citric acid and sodium citrate. Arformoterol tartrate inhalation solution requires no dilution before administration by nebulization. Like all other nebulized treatments, the amount delivered to the lungs will depend upon patient factors, the nebulizer used, and compressor performance. Using the PARI LC ® Plus nebulizer (with mouthpiece) connected to a PARI DURA NEB™ 3000 compressor under in vitro conditions, the mean delivered dose from the mouthpiece (% nominal) was approximately 4.1 mcg (27.6%) at a mean flow rate of 3.3 L/min. The mean nebulization time was 6 minutes or less. Arformoterol tartrate inhalation solution should be administered from a standard jet nebulizer at adequate flow rates via face mask or mouthpiece. Patients should be carefully instructed on the correct use of this drug product (please refer to the accompanying Patient Information ). Image
