Hydroxyapatite carriers as drug eluting agents-An In Vitro analysis.

Introduction Hydroxyapatite based drug carriers offer a customized alternative to the delivery of pharmacologic agents in the osseous skeleton. They have an added advantage of being biocompatible and osteoconductive. This in vitro study aims to quantify the drug eluting properties of HA granules by spectrophotometry. Materials and Methods HA and HASi beads were loaded with gentamicin/ amoxycillin- clavulanate/ vancomycin and grouped into 5. Drug elution was evaluated by means of UV spectrophotometry. Results Drug eluent levels were well above bactericidal levels in all 5 groups. Conclusion HA and HASi are viable options for clinicians for targeted drug delivery.
