STABILIZED PHARMACEUTICAL COMPOSITIONS OF HALOFUGINONE AND OTHER QUINAZOLINONE DERIVATIVES

摘要

The present invention relates to acid stabilized compositions containing as an active ingredient a quinazolinone derivative, preferably halofuginone or a pharmaceutically acceptable salt of halofuginone. More particularly the present invention relates to use of an acid for improving the stability of a topical, parenteral or oral composition containing quinazolinone derivatives as an active ingredient, preferably halofuginone. Surprisingly, even dry solid tablet dosage forms showed improved stability by addition of an acidic component.
