If health authorities such as the European Medicines Agency (EMA) approve the study medicine for use by patients with a specific condition, doctors and pharmacists will become aware that it can be prescribed. Pfizer typically releases public statements when its new medicines are approved, and we list our approved medicines on Pfizer.com. We also commonly create websites and other materials to inform doctors about our medicines.
Keep in mind that study medicines typically go through a series of clinical trials before they are submitted to health authorities for approval. For a study medicine to be considered for approval, those clinical trials must collectively show that the study medicine is safe and effective. Since clinical trials at the PCRU in Brussels are typically phase 1 trials, approval may be years away or may never come.
