The chemical name of ceftolozane sulfate is 1 H -Pyrazolium, 5-amino-4-[[[(2-aminoethyl)amino]carbonyl]amino]-2-[[(6 R ,7 R )-7-[[(2 Z )-2-(5-amino-1,2,4-thiadiazol-3-yl)-2-[(1-carboxy-1-methylethoxy)imino]acetyl]amino]-2-carboxy-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-en-3-yl]methyl]-1-methyl-,sulfate (1:1). The molecular formula is C 23 H 31 N 12 O 8 S 2 + ∙HSO 4 - and the molecular weight is 764.77. Figure 1: Chemical structure of ceftolozane sulfate Tazobactam sodium, a derivative of the penicillin nucleus, is a penicillanic acid sulfone. Its chemical name is sodium (2S,3S,5R)-3-methyl-7-oxo-3-(1H-1,2,3-triazol-1-ylmethyl)-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylate-4,4-dioxide. The chemical formula is C 10 H 11 N 4 NaO 5 S and the molecular weight is 322.3. Figure 2: Chemical structure of tazobactam sodium ZERBAXA 1.5 g (ceftolozane and tazobactam) for injection is a white to yellow sterile powder for reconstitution consisting of ceftolozane 1 g (equivalent to 1.147 g of ceftolozane sulfate) and tazobactam 0.5 g (equivalent to 0.537 g of tazobactam sodium) per vial, packaged in single-dose glass vials. The product contains sodium chloride (487 mg/vial) as a stabilizing agent, citric acid (21 mg/vial), and L-arginine (approximately 600 mg/vial) as excipients. Figure 1 Figure 2

Bezlotoxumab is a human monoclonal antibody that binds to C. difficile toxin B and neutralizes its effects. Bezlotoxumab is an IgG 1 immunoglobulin with an approximate molecular weight of 148.2 kDa. ZINPLAVA (bezlotoxumab) Injection is a sterile, preservative-free, clear to moderately opalescent, colorless to pale yellow solution that requires dilution for intravenous infusion. The product is provided in a 50 mL vial that contains 1000 mg of bezlotoxumab in 40 mL of solution. Each mL of solution contains bezlotoxumab (25 mg), citric acid monohydrate (0.8 mg), diethylenetriaminepentaacetic acid (0.0078 mg), polysorbate 80 (0.25 mg), sodium chloride (8.77 mg), sodium citrate dihydrate (4.75 mg), and Water for Injection, USP. The vial may contain sodium hydroxide to adjust the pH to 6.0.

ZOLINZA contains vorinostat, which is described chemically as N- hydroxy- N'- phenyloctanediamide. The empirical formula is C 14 H 20 N 2 O 3 . The molecular weight is 264.32 and the structural formula is: Vorinostat is a white to light orange powder. It is very slightly soluble in water, slightly soluble in ethanol, isopropanol and acetone, freely soluble in dimethyl sulfoxide and insoluble in methylene chloride. It has no chiral centers and is non-hygroscopic. The differential scanning calorimetry ranged from 161.7 (endotherm) to 163.9°C. The pH of saturated water solutions of vorinostat drug substance was 6.6. The pKa of vorinostat was determined to be 9.2. Each 100 mg ZOLINZA capsule for oral administration contains 100 mg vorinostat and the following inactive ingredients: microcrystalline cellulose, sodium croscarmellose and magnesium stearate. The capsule shell excipients are titanium dioxide, gelatin and sodium lauryl sulfate. Chemical Structure
