Discussion: The ethical conscience of a pharmaceutical company is held by its medical director. Pharmaceutical physicians, therefore, hold an obligation to ensure that evidence on which medicine availability is made is publicised. The outcome of all clinical trials conducted on a medicine should be intended for publication and made freely available. Data which exists "on file" should be of the same quality as published data, with the application of the same scientific criteria. Prescribing doctors wishing to use medicines for unlicensed indications or dosage regimes, but on which a company has relevant scientific data, should have that data made available to them on request.
