Description

Plazomicin is a novel aminoglycoside antibiotic that binds to the bacterial 30S ribosomal subunit, thus inhibiting protein synthesis in a concentration-dependent manner. Plazomicin displays a broad spectrum of activity against aerobic gram-negative bacteria including extended-spectrum β-lactamase-producing Enterobacteriaceae, carbapenem-resistant Enterobacteriaceae, and organisms with aminoglycoside-modifying enzymes. Plazomicin resistance in Enterobacteriaceae is via modification of the ribosomal binding site due to expression of 16S rRNA methyltransferases. ZEMDRI (plazomicin) injection for intravenous use is indicated for the treatment of patients 18 years of age or older with Complicated Urinary Tract Infections (cUTI) including Pyelonephritis.

Sample Use Guides

In Vivo Use Guide
Administer ZEMDRI 15 mg/kg every 24 hours by intravenous (IV) infusion over 30 minutes to patients 18 years of age or older with creatinine clearance greater than or equal to 90 mL/min.
Route of Administration: Intravenous
In Vitro Use Guide
MIC50/MIC90 values for plazomicin were the lowest of all the drugs tested: 0.5/0.5 mg/L for 96 KPC-producing Klebsiella pneumoniae isolates and 0.5/1 mg/L for all 110 carbapenemase-producing isolates. Plazomicin (ACHN-490) inhibited the growth of AG-resistant Enterobacteriaceae (MIC(90), ≤4 μg/ml), with the exception of Proteus mirabilis and indole-positive Proteae (MIC(90), 8 μg/ml and 16 μg/ml, respectively). ACHN-490 was more active alone in vitro against Pseudomonas aeruginosa and Acinetobacter baumannii isolates with AG-modifying enzymes than against those with altered permeability/efflux. The MIC(90) of ACHN-490 against AG-resistant staphylococci was 2 μg/ml.
