Drug repurposing, also known as drug repositioning, is a drug development strategy predicated on the reuse of existing licensed drugs for new medical indications.



+ Drugs taken from libraries containing products known to react with pathways critical e.g. for neurological disorders.

+ Less Chemistry Manufacturing and Controls (CMC) work to be done (formulation study only).

+ About 3 year faster market entry, since approval could refer to existing publications and approval data from originator.

+ No or limited preclinical Tox/Safety to be conducted.

+ No or limited clinical phase I needs to be done in US.

+ Costs less.

+ Significantly lower development risk (safety in humans already shown).
