Проведены сравнительные биологические исследования различных лекарственных форм митоксантрона in vitro и in vivo. Исследования in vitro оказались непоказательными для липосомальной формы митоксантрона, наилучший цитотоксический эффект проявила субстанция. Напротив, проведенные исследования in vivo липосомальной формы митоксантрона в сравнении с субстанцией и митоксантроном-ЛЭНС на экспериментальных перевиваемых опухолях мышей Са-755 и P-388 показали высокий терапевтический эффект. Препараты мышам вводили внутривенно трехкратно с интервалом 96 ч. Показано, что липосомальная лекарственная форма митоксантрона позволяет повысить биодоступность препарата и снизить дозу в 6 раз.
In this study we have examined the activity of various drug formulations of mitoxantrone in vitro and in vivo. Our in vitro data indicated that the liposomal mitoxantrone was not as effective as free form of drug. However, in vivo animal models Ca-755 and P-388 the effect of liposomal form of mitoxantrone was much more promising in compare with free form of drug. The mitoxantrone formulations were injected into mice at a therapeutic dose regimen with a 96 h interval. The overall results of this study suggest that liposomal mitoxantrone increases the bioavailability of a preparation and reduces the dose for about 6-fold.
