  • CASPOFUNGIN FORMULATIONS
    Publication number: 20130028940
    Abstract: The present invention relates to pharmaceutical compositions comprising a pharmaceutically acceptable salt of caspofungin as active ingredient being useful for the prevention and/or treatment of fungal infections. Said compositions additionally comprise specific bulking agents and small amounts or no amounts of an additional pH modifier and may be in a liquid or solid form, e.g. may be lyophilized compositions. Said compositions show good stability and reduced amounts of sub-visible particulate matter formed in solutions which are reconstituted from the lyophilized product.
