BEVESPI AEROSPHERE (glycopyrrolate and formoterol fumarate) Inhalation Aerosol is a pressurized metered-dose inhaler that contains a combination of micronized glycopyrrolate, an anticholinergic, and micronized formoterol fumarate, a long-acting beta 2 -adrenergic agonist, for oral inhalation. Glycopyrrolate is a quaternary ammonium salt with the following chemical name: ( RS )-[3-( SR )-Hydroxy-1,1-dimethylpyrrolidinium bromide] α-cyclopentylmandelate. Glycopyrrolate is a powder that is freely soluble in water. The molecular formula is C 19 H 28 BrNO 3 , and the molecular weight is 398.33 g/mol. The structural formula is as follows: Glycopyrrolate contains two chiral centers (denoted by * in structure above) and is a racemate of a 1:1 mixture of the R,S and S,R diastereomers. The active moiety, glycopyrronium, is the positively charged ion of glycopyrrolate. Formoterol fumarate has the chemical name N -[2-Hydroxy-5-[(1RS)-1-hydroxy-2-[[(1RS)-2-(4-methoxyphenyl)-1- methylethyl]-amino] ethyl]phenyl] formamide, €-2-butenedioate dihydrate. Formoterol fumarate is a powder that is slightly soluble in water. The molecular formula is (C 19 H 24 N 2 O 4 ) 2 .C 4 H 4 O 4 .2H 2 O and the molecular weight is 840.91 g/mol. The structural formula is as follows: Formoterol fumarate contains two chiral centers (denoted by * in structure above), and consists of a single enantiomeric pair (a racemate of R,R and S,S). BEVESPI AEROSPHERE is formulated as a hydrofluoroalkane (HFA 134a) propelled pressurized metered dose inhaler containing 120 inhalations. The canister has an attached dose indicator and is supplied with a white plastic actuator body and mouthpiece with an orange dust cap. After priming each actuation of the inhaler meters 10.4 mcg of glycopyrrolate (equivalent to 8.3 mcg of glycopyrronium) and 5.5 mcg of formoterol fumarate from the valve which delivers 9 mcg of glycopyrrolate (equivalent to 7.2 mcg of glycopyrronium) and 4.8 mcg of formoterol fumarate from the actuator. The actual amount of drug delivered to the lung may depend on patient factors, such as the coordination between actuation of the device and inspiration through the delivery system. BEVESPI AEROSPHERE also contains porous particles that form a cosuspension with the drug crystals. The porous particles are comprised of the phospholipid, 1,2-Distearoyl- sn -glycero-3-phosphocholine (DSPC), and calcium chloride. Porous particles and HFA 134a are excipients in the formulation. The Structural Formula of Glycopyrrolate contains two chiral centers (denoted by * in structure above) and is a racemate of a 1:1 mixture of the R,S and S,R diastereomers. The Structural Formula of Formoterol fumarate contains two chiral centers (denoted by * in structure above), and consists of a single enantiomeric pair (a racemate of R,R and S,S).
