DAPTOMYCIN MODE OF ACTION
Daptomycin is a cyclic lipopeptide natural product that is active against Gram positive bacteria only.
The mechanism of action involves binding (in the presence of calcium ions) to bacterial membranes of both growing and stationary phase cells causing depolarisation and leading to a rapid inhibition of protein, DNA, and RNA synthesis. This results in bacterial cell death with negligible cell lysis.
INDICATIONS
Daptomycin is indicated for the treatment of the following infections:.
– Adult and paediatric (1 to 17 years of age) patients with complicated skin and soft-tissue infections (cSSTI).
– Adult patients with right-sided infective endocarditis (RIE) due to Staphylococcus aureus. It is recommended that the decision to use daptomycin should take into account the antibacterial susceptibility of the organism and should be based on expert advice.
– Adult and paediatric (1 to 17 years of age) patients with Staphylococcus aureus bacteraemia (SAB). In adults, use in bacteraemia should be associated with RIE or with cSSTI, while in paediatric patients, use in bacteraemia should be associated with cSSTI.
Daptomycin is active against Gram positive bacteria only . In mixed infections where Gram negative and/or certain types of anaerobic bacteria are suspected, Daptomycin should be co-administered with appropriate antibacterial agent(s).
DOSAGE AND ADMINISTRATION:
– cSSTI without concurrent SAB: Daptomycin 4 mg/kg is administered once every 24 hours for 7-14 days or until the infection is resolved
– cSSTI with concurrent SAB: Daptomycin 6 mg/kg is administered once every 24 hours. The duration of therapy may need to be longer than 14 days in accordance with the perceived risk of complications in the individual patient.
– Known or suspected RIE due to Staphylococcus aureus: Daptomycin 6 mg/kg is administered once every 24 hours. The duration of therapy should be in accordance with available official recommendations.
Daptomycin is administered intravenously in 0.9% sodium chloride . Daptomycin should not be used more frequently than once a day.
CONTRAINDICATIONS:
Daptomycin is contraindicated in patients with known hypersensitivity to it.
DRUG INTERACTIONS:
Daptomycin undergoes little to no Cytochrome P450 (CYP450)-mediated metabolism. It is unlikely that daptomycin will inhibit or induce the metabolism of medicinal products metabolised by the P450 system.
Inhibitors of HMG-CoA reductase may cause myopathy, which is manifested as muscle pain or weakness associated with elevated levels of creatine phosphokinase (CPK).
Caution is warranted when Daptomycin is co-administered with tobramycin.

Reporting of suspected adverse reactions:
The PPB Department of Pharmacovigilance was set up with a vision to develop, implement and continuously upgrade an appropriate system for detecting, reporting, and monitoring adverse drug reactions (ADRs) and other relevant problems with medicines in Kenya. The department strives to ensure the safety and efficacy of pharmaceutical products in Kenya.
Reporting suspected adverse reactions after authorization of the medicinal product are important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals/ Patients are encouraged to report any suspected adverse reactions via Pharmacovigilance Yellow Form, pv@pharmacyboardkenya.org or clicking below button:
