Daptomycin is not specifically indicated for post-stroke patients as it is an antibiotic used to treat bacterial infections, not stroke-related conditions. It is primarily used for complicated skin and skin structure infections, bloodstream infections, and right-sided endocarditis caused by susceptible gram-positive bacteria, particularly methicillin-resistant Staphylococcus aureus (MRSA) 1. In post-stroke patients, daptomycin would only be prescribed if they develop a specific bacterial infection that warrants its use, such as healthcare-associated pneumonia, urinary tract infections, or bloodstream infections with susceptible organisms. The typical dosage is 4-6 mg/kg administered intravenously once daily for skin infections and 6-8 mg/kg for bacteremia or endocarditis, with treatment duration typically 7-14 days depending on the infection site and severity 2. Daptomycin works by disrupting multiple aspects of bacterial cell membrane function without penetrating the cytoplasm. It's essential to monitor creatine phosphokinase (CPK) levels weekly during therapy as daptomycin can cause myopathy, and the drug should be used cautiously in patients with renal impairment with appropriate dose adjustments 3. Some studies have explored the use of high-dose daptomycin (>6 mg/kg) for difficult-to-treat Gram-positive infections, but its use in post-stroke patients would still be guided by the presence of a specific bacterial infection requiring such treatment 4, 5. Key considerations in the use of daptomycin include its effectiveness against MRSA and vancomycin-resistant Enterococcus, its once-daily dosing, and the need for careful monitoring of potential side effects, especially in patients with pre-existing renal impairment or muscle disease. Given the potential for resistance development, it is crucial to use daptomycin judiciously and only when clearly indicated by the clinical scenario. In the context of post-stroke care, the focus should remain on preventing infections through good hygiene practices, appropriate use of prophylactic antibiotics when necessary, and prompt treatment of any infections that do occur, with daptomycin being one of the options for gram-positive infections when other treatments are not suitable.
