  3. E coll, K.pneumoniae, P. aeruginosa, Bacteroides caccae, B. fragilis, B. thetaiotaomicron, B uniformis, B. vulgatus, S. intermedius, S. constellatus and Peptostreptococcus micros
  4. E col including cases with concurrent bacteremia, K. pneumoniae, P. mirabilis, P. aeruginosa and A. baumannii

Daptomycin should be administered intravenously either by injection over a 2 minute period or by infusion over a 30 minute period.

Reconstitution & Dilution:
  • Constitutes the vial with 10 mL of sterile water for injection or 0.9% NaCl and gently shake to form a suspension". The resultant concentration is 50 mg/mL
  • Withdraw the suspension using a syringe and add it to an infusion bag containing 100 mL of normal saline or 5% dextrose; gently shake until clear. The final infusion solution concentration is 4.5 mg/mL.
  • Doripenem has a broad spectrum of activity against Gram-positive, Gram-negative and anaerobic bacteria including MDR strains, most notably the ESBL and Amp-C B-lactamase producing Gram-negative organisms.
  • Doripenem is the higher activity against P. aeruginosa than the rest of Carbapenems, so it is especially useful for severe infections caused by MDR P. aeruginosa.
  • Doripenem has less seizure potential as it has the lowest GABA receptor binding affinity among the Carbapenems.
  • Doripenem has longer stability in solution than Imipenem or Meropenem; this allows the drug to be administered for extended infusion durations (4 hours), thus optimizing pharmacokinetic/ pharmacodynamic parameters to target less susceptible pathogens.
  • Among Carbapenems, Doripenem is more potent against P. aeruginosa than Imipenem and Meropenem, and it exhibits lesser propensity for development of resistant strains.
