tiotropium bromide and olodaterol - Generic Medications

STIOLTO RESPIMAT is a combination of tiotropium, an anticholinergic, and olodaterol, a long-acting beta 2 -adrenergic agonist (LABA). The drug substance tiotropium bromide monohydrate is chemically described as (1α, 2ß, 4ß, 5α, 7ß)-7-[(Hydroxydi-2-thienylacetyl)oxy]-9,9-dimethyl-3-oxa-9-azoniatricyclo[3.3.1.0 2,4 ] nonane bromide monohydrate. It is a synthetic, non-chiral, quaternary ammonium compound. Tiotropium bromide is a white or yellowish white powder. It is sparingly soluble in water and soluble in methanol. The structural formula is: Tiotropium bromide (monohydrate) has a molecular mass of 490.4 and a molecular formula of C 19 H 22 NO 4 S 2 Br ∙ H 2 O. The drug substance olodaterol hydrochloride is chemically described as 2H-1,4-Benzoxazin-3H(4H)-one, 6-hydroxy-8-[(1R)-1-hydroxy-2-[[2-(4-methoxyphenyl)-1,1-dimethylethyl]-amino]ethyl]-, monohydrochloride. Olodaterol hydrochloride is a white to off-white powder that is sparingly-slightly soluble in water and slightly soluble in ethanol. The molecular weight is 422.9 g/mole (salt): 386.5 g/mole (base), and the molecular formula is C 21 H 26 N 2 O 5 × HCl as a hydrochloride. The conversion factor from salt to free base is 1.094. The structural formula is: The drug product, STIOLTO RESPIMAT, is composed of a sterile aqueous solution of tiotropium bromide and olodaterol hydrochloride filled into a 4.5 mL plastic container crimped into an aluminum cylinder (STIOLTO RESPIMAT cartridge) for use with the STIOLTO RESPIMAT inhaler. Excipients include, benzalkonium chloride, edetate disodium, hydrochloric acid, and water for injection. The STIOLTO RESPIMAT cartridge is only intended for use with the STIOLTO RESPIMAT inhaler. The STIOLTO RESPIMAT inhaler is a hand held, pocket sized oral inhalation device that uses mechanical energy to generate a slow-moving aerosol cloud of medication from a metered volume of the drug solution. The STIOLTO RESPIMAT inhaler has a light green-colored cap. When used with the STIOLTO RESPIMAT inhaler each cartridge, containing 4 grams of sterile aqueous solution, delivers the labeled number of metered actuations after preparation for use. Each dose (one dose equals two actuations) from the STIOLTO RESPIMAT inhaler delivers 5 mcg tiotropium (equivalent to 6.247 mcg tiotropium bromide monohydrate) and 5 mcg olodaterol (equivalent to 5.473 mcg olodaterol hydrochloride) in 22.1 mcL from the mouthpiece. As with all inhaled drugs, the actual amount of drug delivered to the lung may depend on patient factors, such as the coordination between the actuation of the inhaler and inspiration through the delivery system. The duration of inspiration should be at least as long as the spray duration (1.5 seconds). Chemical Structure Chemical Structure
