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

• Bacteremia
• Skin and Subcutaneous Tissue Bacterial Infections
• Right-sided Infective pericarditis

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 destabilization
ULipoteichoic acid synthesis	inhibitor	Gram 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%)

Taxonomy

Description

This compound belongs to the class of organic compounds known as cyclic depsipeptides. These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually α-amino and α-hydroxy acids) connected in a ring. The residues are commonly but not necessarily regularly alternating.
