Regulatory procedures for obtaining marketing authorization of medicines in the European Union are described. There are several types of authorization procedures including the centralised procedure, mutual recognition procedure, and decentralized procedure. Conditional approval may be granted if the risk-benefit balance is positive, comprehensive data will likely be provided, and unmet medical needs will be fulfilled. Accelerated assessment can be requested for products that are major therapeutic innovations or of major public health interest. Compassionate use programs make products available for named patients or cohorts when a product has not yet received full authorization.
