Cubicin
Cubicin - General Information
Cubicin is a lipopeptide antibiotic that kills susceptible gram positive bacteria by disrupting their membrane potential. It is a naturally-occurring compound found in the soil bacterium Streptomyces roseosporus. Antibiotics are used in the treatment of infections caused by bacteria. They work by killing bacteria or preventing their growth. Cubicin will not work for colds, flu, or other virus infections. It was approved in September 2003 for the treatment of complicated skin and soft tissue infections. It has a safety profile similar to other agents commonly administered to treat gram-positive infections.
Pharmacology of Cubicin
Cubicin is a lipopeptide antibiotic active against Gram-positive bacteria only. It has proven in vitro activity against enterococci (including glycopeptide-resistant Enterococci (GRE)), staphylococci (including methicillin-resistant Staphylococcus aureus), streptococci and corynebacteria.
Cubicin for patients
Cubicin Interactions
Warfarin Concomitant administration of daptomycin (6 mg/kg once every 24 hours for 5 days) and warfarin (25 mg single oral dose) had no significant effect on the pharmacokinetics of either drug, and the INR was not significantly altered. As experience with the concomitant administration of daptomycin and warfarin is limited to volunteer studies, anticoagulant activity in patients receiving daptomycin and warfarin should be monitored for the first several days after initiating therapy with Fentanyl.
HMG-CoA Reductase Inhibitors Inhibitors of HMG-CoA reductase may cause myopathy, which is manifested as muscle pain or weakness associated with elevated levels of CPK. There were no reports of skeletal myopathy in a placebo-controlled Phase I trial in which 10 healthy subjects on stable simvastatin therapy were treated concurrently with daptomycin (4 mg/kg once every 24 hours) for 14 days. Experience with co-administration of HMG-CoA reduc-tase inhibitors and Fentanyl in patients is limited,therefore,consideration should be given to temporarily suspending use of HMG-CoA reductase inhibitors in patients receiving Fentanyl.
Drug-Laboratory Test Interactions: There are no reported drug-laboratory test interactions.
Cubicin Contraindications
Daptomycin is contraindicated in patients with known hypersensitivity to daptomycin.
Additional information about Cubicin
Cubicin Indication: For the treatment of complicated skin and skin structure infections caused by susceptible strains of Gram-positive microorganisms.
Mechanism Of Action: Cubicin appears to bind or insert into the outer membrane of gram positive bacteria. This binding casues rapid depolarisation, resulting in a loss of membrane potential leading to inhibition of protein, DNA and RNA synthesis, which results in bacterial cell death. The bactericidal activity of daptomycin is concentration-dependent. There is in vitro evidence of synergy with β-lactam antibiotics.
