YUPELRI is a sterile, clear, colorless, aqueous solution of revefenacin. Revefenacin, the active component of YUPELRI, is an anticholinergic. The chemical name for revefenacin is 1-(2-{4-[(4-carbamoylpiperidin-1-yl)methyl]- N -methylbenzamido}ethyl)piperidin-4-yl N -({1,1’-biphenyl}-2-yl)carbamate; its structural formula is: Revefenacin has a molecular weight of 597.76 and its empirical formula is C 35 H 43 N 5 O 4 . Revefenacin is a white to off-white crystalline powder and is slightly soluble in water. YUPELRI is supplied as 3 mL of revefenacin solution packaged in a unit-dose low-density polyethylene vial overwrapped in a foil pouch. Each vial contains 175 mcg of revefenacin in 3 mL of an isotonic, sterile aqueous solution containing citric acid, sodium chloride, sodium citrate, and water for injection at pH 5.0. Hydrochloric acid or sodium hydroxide may be used to adjust the pH. YUPELRI 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, the nebulization system used, and compressor performance. Using the PARI LC ® Sprint nebulizer connected to a PARI Trek ® S compressor under in vitro conditions, the mean delivered dose from the mouthpiece was approximately 62 mcg (35% of label claim), at a mean flow rate of 4 LPM. The mean nebulization time was 8 minutes. YUPELRI should only be administered via a standard jet nebulizer connected to an air compressor with an adequate airflow, and equipped with a mouthpiece.
