- Description
Daptomycin 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. Daptomycin 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
- Indication
For the treatment of complicated skin and skin structure infections caused by susceptible strains of Gram-positive microorganisms.
- Associated Conditions
- Pharmacodynamics
Daptomycin is a 13 member amino acid cyclic 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. Daptomycin is derived from the fermentation product of Streptomyces roseosporus.
- Mechanism of action
Daptomycin appears to bind or insert into the outer membrane of gram positive bacteria. The binding and integration of daptomycin into the cell membrane is calcium dependent. Calcium ions cause a conformational change in daptomycin, augmenting its amphipathicity (hydrophilic head group and hydrophobic tail group), leading to incorporation into the cell membrane. This binding causes 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.
Target Actions Organism ABacterial outer membrane incorporation into and destabilizationULipoteichoic acid synthesis inhibitorGram positive bacteria - Absorption
Generally exhibits linear and time-independent pharmacokinetics at a dosage of 4–12 mg/kg IV once every 24 hours. Steady-state trough serum concentrations are achieved by the third daily dose.
- Volume of distribution
- 0.1 L/Kg [healthy adult subjects]
- Protein binding
Daptomycin is reversibly bound to human plasma proteins, primarily to serum albumin, in a concentration-independent manner. The overall mean binding ranged from 90 to 93%.
- Metabolism
Minor amounts of three oxidative metabolites and one unidentified compound have been detected in urine. The site of metabolism has not been identified.
- Route of elimination
Daptomycin is excreted primarily by the kidney. In a mass balance study of 5 healthy subjects using radiolabeled daptomycin, approximately 78% of the administered dose was recovered from urine based on total radioactivity (approximately 52% of the dose based on microbiologically active concentrations) and 5.7% of the dose was recovered from feces (collected for up to 9 days) based on total radioactivity. Because renal excretion is the primary route of elimination, dosage adjustment is necessary in patients with severe renal insufficiency (CLCR <30 mL/min)
- Half life
Half-life elimination: 8-9 hours (up to 28 hours in renal impairment)
- Clearance
Excreted primarily in the urine as unchanged drug (78%) and in the feces (6%)

Drug Interaction (R)-warfarin The risk or severity of bleeding can be increased when Daptomycin is combined with (R)-warfarin. (S)-Warfarin The risk or severity of bleeding can be increased when Daptomycin is combined with (S)-Warfarin. 4-hydroxycoumarin The risk or severity of bleeding can be increased when Daptomycin is combined with 4-hydroxycoumarin. Abacavir Daptomycin may decrease the excretion rate of Abacavir which could result in a higher serum level. Acarbose Daptomycin may decrease the excretion rate of Acarbose which could result in a higher serum level. Aceclofenac Aceclofenac may decrease the excretion rate of Daptomycin which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Daptomycin which could result in a higher serum level. Acenocoumarol The risk or severity of bleeding can be increased when Daptomycin is combined with Acenocoumarol. Acetaminophen Daptomycin may decrease the excretion rate of Acetaminophen which could result in a higher serum level. Acetazolamide Acetazolamide may increase the excretion rate of Daptomycin which could result in a lower serum level and potentially a reduction in efficacy. - Food Interactions
