New User Registration (Why Registration?)

The Safety and Toxicity of Excipients for Paediatrics ("STEP") Database, including all of its features and content is hosted by the University College London ("UCL"), and may be used solely under the following terms and conditions ("Terms of Use").

These Terms of Use (together with the documents referred to in it) inform you the terms of use for accessing and utilising the STEP Database (the "Database"), whether as a guest or a registered user. Use of the Database includes accessing, browsing, or registering to use the Database.

About the Database: The STEP Database is an user-designed resource that compiles the safety and toxicity data of excipients that is scattered over various sources (whether in public, private or informal sectors) and presents it in one freely accessible source.It holds high level specific safety and toxicity data on target age groups, route of administration, treatment duration, concentration, maximum daily excipient intake and exposure.The focus of the STEP database is to provide clinical and non-clinical adverse effects and tolerability data for each excipient. It is fully searchable and allows filtering the data for paediatrics and adults use. This dual nature of the database, in which safety and toxicity data can be searched in both directions, makes it unique from existing databases.

The critical appraisal of the references is out of scope of the STEP database and so the database will not provide any interpretive comments. Hence, a user will be encouraged to access such information at the source/link provided. Also, the responsibility of using this information appropriately will always remain with the end user using it.
