Abstract: The mouse lung concentration of methotrexate (MTX) following the intravenous administration of MTX solution and MTX bovine serum albumin (BSA) microspheres was investigated. The therapeutic effects of the two MTX preparations on lung-bearing sarcomal-80 in mice were also studied. It was found that the AUC of the MTX microspheres group was about 7 times as much as that of the MTX solution group, and the MTX microspheres had better effects on lung-bearing sarcoma-180 than the MTX solution did.
