Bone cements have been widely used to fill the dead space of bone tissues in orthopaedic surgeries.Loaded with antibiotics,these materials are also administered for the prevention and treatment of infections,infectious osteomyelitis for example.We made polymethylmethacrylate cement preparations of five commercial vancomycin (VCM) products and compared the in vitro dissolution profiles of the VCM in them and mechanical strengths of the cements.When immersed in phosphate buffer (PB) for 30 days,dissolved amounts of VCM ranged between just 5 and 19% of the calculated contents and after immersion in PB for 40 days mechanical strengths were significantly decreased (50-75% of the control without VCM).Further,on testing a cement preparation containing pharmaceutical additives as well as VCM,the amount of antibiotic released was significantly larger than that for other preparations and the release was more rapid as well.This cement preparation also had the lowest strength among those studied.By doing this,we showed that pharmaceutical additives could have marked effect on the dissolution of the antibiotic and mechanical strength for antibiotic-laden bone cements for the first time,though these were in vitro findings.The present study clearly demonstrated that the antibiotic products used can cause functional differences in antibioticladen bone cements and also suggested that pharmaceutical additives influence cement functions.It is therefore necessary to pay attention to both the antibiotic content of commercial VCM products and types of pharmaceutical additive in the preparation of such cements.

To elucidate the current status of the dosage regimen of vancomycin, we reviewed its therapeutic drug monitoring (TDM) data obtained from 99 patients undergoing vancomycin treatment at the Chugoku Rousai Hospital. The plasma concentrations of vancomycin at one dosage under 750 mg deviated from its therapeutic ranges (the level at one hour after the end of infusion : 25-40 μg/mL, trough level :≦10μg/mL). Therefore, the dosing interval at a uniform dosage of 1000 mg was calculated from a vancomycin nomogram reported by Moellering et al., and the utility of the dosing interval at the uniform dosage of 1000 mg combined with a creatinine clearance nomogram reported by Nielsen et al. was examined. As a result, the plasma levels of 66 percent of the subjects were controlled within the accepted therapeutic ranges in the early stage. Accordingly, the nomogram of vancomycin prepared as an indication in the early stage in our hospital was thus concluded to be clinically acceptable.
