Research Abstract |
Hydrosyapatite(HAp) has excellent compatibility wity human sissues and is used in percutameous devices. as well as in orthopedic and dental procedures. Thedrug carrier HAp particle has ores 23-59 mu m in diameter with surface area of 2.5m^2/g. The drug delivery system carboplatin-loaded Hap particles (HAp-CBDCA) was contained 200mg HAp and 4mg CBDCA.The efficacy of intraperitoneal administration of HAp-CBDCA was wxplored using a Donryu rat model of tumor cell AH-130 carcinomatous peritonitis. The pharmacokinetics of CBDCA following intraperitoneal administration of HAp-CBDCA was studied. Serum levels of CBDCA were higher in HAp-CBDCA group wity the free CBDCA group from post-drug administration hour 6 unil hour 24. We found that intraperitoneal administration of HAp-CBDCA was effective in prolongation of rats bearing AH-130 in peritoneal cavity. These results demonstrate the effecacy of HAp particles as carrier for anticancer drugs, with ultimate improvement in overall survival.
