orphan drugsA drug used to treat a rare disease and for which the market is so small that manufacturers have little incentive to go to the expense of producing them. In1983 US legislation provided financial incentives, in the form of tax credits and 7 year exclusive rights, to firms willing to produce such drugs. This has been effective and, by mid-2003, 229 orphan drugs were available.
