Description	OHTUVAYRE (ensifentrine) is a sterile, yellow to pale yellow aqueous inhalation suspension of ensifentrine for oral inhalation. Ensifentrine, the active component of OHTUVAYRE, is an inhibitor of phosphodiesterases 3 and 4 (PDE3 and PDE4). The chemical name for ensifentrine is N-(2-{(2E)-9,10-dimethoxy-4-oxo-2-[(2,4,6-trimethylphenyl)imino]-6,7-dihydro-2H-pyrimido[6,1-a]isoquinolin-3(4H)-yl}ethyl)urea; its structural formula is. Ensifentrine has a molecular weight of 477.56 and its empirical formula is C26H31N5O4. Ensifentrine is a yellow to pale yellow crystalline powder which is practically insoluble in water. OHTUVAYRE is supplied as 2.5 mL of sterile ensifentrine (1.2 mg/mL) suspension packaged in a unit-dose low-density polyethylene ampule overwrapped in a sealed foil pouch. Each unit-dose ampule contains 3 mg ensifentrine suspended in a pH 6.7 aqueous solution containing dibasic sodium phosphate, monobasic sodium phosphate, polysorbate 20, sodium chloride, sorbitan monolaurate and water for injection. The ampule containing OHTUVAYRE should be shaken vigorously to ensure complete resuspension of the active ingredient immediately 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® jet nebulizer attached to a PARI Vios Pro® compressor under in vitro conditions, the mean delivered dose from the mouthpiece was approximately 933 micrograms (31% of label claim) at a mean flow rate of approximately 5 liters per minute. The mean nebulization time was approximately 7 minutes. The mass median aerodynamic diameter (MMAD) of the nebulized particles/droplets using the PARI LC Sprint® jet nebulizer attached to a PARI Vios Pro® compressor (flow rate approximately 15 L per minute, nebulization time approximately 10 minutes) is 5.82 microns (geometric standard deviation = 1.97) with a typical fine particle dose (mass of aerosolized drug < 5 microns) of approximately 614 micrograms, as determined using the Next Generation Impactor (NGI) method, based on USP <601>. OHTUVAYRE should only be administered via a standard jet nebulizer connected to an air compressor with an adequate airflow and equipped with a mouthpiece.
