GUTIERREZ URBON, J. M.ª; LINARES MONDEJAR, P.  and  MARTIN HERRANZ, I.. Daptomycin dosing greater than 6 mg/kg/day depending on pharmacokinetic and pharmacodynamic parameters infections by Staphylococcus aureus. Farm Hosp. [online]. 2013, vol.37, n.6, pp.534-538.

Daptomycin is a cyclic lipopeptide antibiotic whose approved dose is 4 to 6 mg/kg/day. Today it is a matter of controversy the use of higher doses of daptomycin in a range of 8-12 mg/kg/ day, for the treatment of Staphylococcus aureus infections, justified by its concentration-dependent action and its tolerability and safety profile, but the available studies are inconclusive. Stratification is performed by groups of patients, on the recommendation of using doses above 6 mg/kg/day based on the PK/PD parameters predictive of efficacy and safety. We conclude that doses of 8-12 mg/kg/day may be beneficial in patients with severe sepsis, patients with hypoalbuminemia and infections involving potentially high bacterial load or where there is a bacterial kidnapping. However it is not suitable exceed the dose of 6 mg/kg/day in patients with obesity and/or creatinine clearance less than 50 ml/min.
