The others are still under development or awaiting authorisation.
Before a drug can be marketed and be available for the patients in a specific country in Europe, however, it may also require additional administrative clearance by the country's authorities (setting of price and public health insurance reimbursement tariffs, for example).
The Enterprise DG list does not provide in-depth details on the drug. However, it provides a trade name for the drug, which you can then use to find in-depth information about the product on the website of the EMA (European Medicines Agency) www.ema.europa.eu. The EMA listing covers all drugs, not just orphan drugs. Information is available in all EU languages.
