Current guidelines recommend vancomycin trough concentrations 15 to 20 µg/mL in complicated infections and all trough concentrations above 10 µg/mL. ⋯ The divided-load vancomycin dosing strategy achieved measured trough concentrations 15 to 20 µg/mL for most critically ill patients within 24 hours of initial dosing, without allowing doses given during supratherapeutic concentrations.

To evaluate daptomycin use for the treatment of infections with methicillin-resistant Staphylococcus aureus (MRSA) isolates having vancomycin minimum inhibitory concentrations (MICs) of 1.5 to 2 µg/mL. ⋯ Current published evidence indicates daptomycin may be an acceptable alternative to vancomycin for MRSA infections, especially bacteremia, involving isolates with vancomycin MIC values of 1.5 to 2 µg/mL. Additional evidence is needed to fully elucidate daptomycin utility in this area.

To review clinical trials and main characteristics of bosutinib, a second-generation tyrosine kinase inhibitor (TKI) for treatment of chronic myelogenous leukemia (CML). ⋯ Currently available clinical trials suggest that bosutinib is generally a safe and effective treatment option for patients with CML who have failed first-line TKIs and who do not express the T315I mutation; however, tolerability may be problematic for some patients.
-
To review currently available literature on the oral multikinase inhibitor regorafenib and its role in the treatment of metastatic colorectal cancer (mCRC), and imatinib- and sunitinib-resistant gastrointestinal stromal tumors (GISTs). ⋯ Regorafenib is a novel oral multikinase inhibitor that has shown promising results for patients with advanced, unresectable or metastatic treatment-refractory CRCs or imatinib- and sunitinib-resistant GISTs.
