Product description

ZEMDRI contains plazomicin sulfate, a semi-synthetic aminoglycoside antibacterial derived from sisomicin. The chemical name of plazomicin sulfate is (2"R,3"R,4"R,5"R)2"[(1S,2S,3R,4S,6R)-4-amino-6-[(2'"S)-4'“-amino-2'”-hydroxybutanamido)amino]3[(2'S,3'R)-3'-amino-6'-((2-hydroxyethylamino)methyl)-3',4'-dihydro-2H-pyran-2'-yloxy]-2-hydroxycyclohexyloxy]-5'‘-methyl-4’‘-(methylamino)tetrahydro-2H-pyran-3’‘,5’'-diol sulfate. Plazomicin sulfate contains a theoretical 2.5 molar equivalents of sulfate relative to the freebase, based on complete protonation. The molecular weight of plazomicin sulfate is calculated based on 1:2.5 stoichiometry. The corresponding empirical formula is C25H48N6O10∙2.5 H2SO4 (plazomicin sulfate) and the molecular weight of the plazomicin sulfate salt is 837.89 g/mol and the molecular weight of the freebase is 592.69 g/mol.

Figure 1. Chemical Structure of Plazomicin Sulfate:

ZEMDRI injection 500 mg/10 mL is a sterile, clear, colorless-to-yellow liquid for intravenous administration supplied in 10-mL single-dose Type 1 glass vials. Each vial contains plazomicin sulfate equivalent to 500 mg plazomicin freebase at a concentration of 50 mg/mL adjusted to pH 6.5. Each vial also contains Water for Injection and sodium hydroxide for pH adjustment. This sterile, nonpyrogenic solution is formulated without preservatives.

Dosage Forms and Strengths

ZEMDRI injection 500 mg/10 mL (50 mg/mL) is a sterile, clear, colorless to yellow solution supplied in a single-dose vial. Each single-dose vial contains plazomicin sulfate equivalent to 500 mg plazomicin freebase.

How Supplied

ZEMDRI injection 500 mg/10 mL (50 mg/mL) is supplied in single-dose, 10-mL vials fitted with flip-off seals with royal blue polypropylene buttons as a clear, colorless to yellow, sterile solution. Each vial contains plazomicin sulfate equivalent to 500 mg plazomicin freebase at a concentration of 50 mg/mL plazomicin in Water for Injection. Each vial contains sodium hydroxide for pH adjustment to 6.5. The solution may become yellow in color; this does not indicate a decrease in potency.
