Teriparatide Injection is a recombinant human parathyroid hormone analog (PTH 1-34). It has an identical sequence to the 34 N-terminal amino acids (the biologically active region) of the 84-amino acid human parathyroid hormone. The molecular formula of Teriparatide is C 181 H 291 N 55 O 51 S 2 and molecular weight is 4117.8 daltons. Its amino acid sequence is shown below: Teriparatide is manufactured using a strain of Escherichia coli modified by recombinant DNA technology. Teriparatide Injection is supplied as a sterile, colorless, clear, isotonic solution in a glass cartridge which is pre-assembled into a single-patient-use delivery device (pen) for subcutaneous injection. Each delivery device (pen) is filled with volume to allow delivery of 2.24 mL. Each mL contains 250 mcg of Teriparatide (as a free base), 0.41 mg of glacial acetic acid, 0.1 mg of sodium acetate (anhydrous), 45.4 mg of mannitol, 3 mg of Metacresol, and Water for Injection. In addition, hydrochloric acid solution 10% and/or sodium hydroxide solution 10% may have been added to adjust the pH to 4. Each prefilled delivery device (pen) delivers 20 mcg of Teriparatide per dose for up to 28 days. Each device contains additional volume to allow troubleshooting of the device 2 times.

Umeclidinium and Vilanterol ELLIPTA is an inhalation powder drug product for delivery of a combination of umeclidinium (an anticholinergic) and vilanterol (a LABA) to patients by oral inhalation. Umeclidinium bromide has the chemical name 1-[2-(benzyloxy)ethyl]-4-(hydroxydiphenylmethyl)-1-azoniabicyclo[2.2.2]octane bromide and the following chemical structure: Umeclidinium bromide is a white powder with a molecular weight of 508.5, and the empirical formula is C 29 H 34 NO 2 •Br (as a quaternary ammonium bromide compound). It is slightly soluble in water. Vilanterol trifenatate has the chemical name triphenylacetic acid-4-{(1 R )-2-[(6-{2-[(2,6-dicholorobenzyl)oxy]ethoxy}hexyl)amino]-1-hydroxyethyl}-2-(hydroxymethyl)phenol (1:1) and the following chemical structure: Vilanterol trifenatate is a white powder with a molecular weight of 774.8, and the empirical formula is C 24 H 33 Cl 2 NO 5 •C 20 H 16 O 2 . It is practically insoluble in water. Umeclidinium and Vilanterol ELLIPTA is a light grey and red plastic inhaler containing 2 foil blister strips. Each blister on one strip contains a white powder blend of micronized umeclidinium bromide (74.2 mcg equivalent to 62.5 mcg of umeclidinium), magnesium stearate (75 mcg), and lactose monohydrate (to 12.5 mg), and each blister on the other strip contains a white powder blend of micronized vilanterol trifenatate (40 mcg equivalent to 25 mcg of vilanterol), magnesium stearate (125 mcg), and lactose monohydrate (to 12.5 mg). The lactose monohydrate contains milk proteins. After the inhaler is activated, the powder within both blisters is exposed and ready for dispersion into the airstream created by the patient inhaling through the mouthpiece. Under standardized in vitro test conditions, Umeclidinium and Vilanterol ELLIPTA delivers 55 mcg of umeclidinium and 22 mcg of vilanterol per dose when tested at a flow rate of 60 L/min for 4 seconds. In adult subjects with obstructive lung disease and severely compromised lung function (COPD with FEV 1 /FVC <70% and FEV 1 <30% predicted or FEV 1 <50% predicted plus chronic respiratory failure), mean peak inspiratory flow through the ELLIPTA inhaler was 66.5 L/min (range: 43.5 to 81.0 L/min). The actual amount of drug delivered to the lung will depend on patient factors, such as inspiratory flow profile. Umeclidinium bromide chemical structure Vilanterol trifenatate chemical structure
