Approved Drug Molecules Screensaver
The Approved Drug Molecules screensaver shows real molecules that reached phase 4 — approved for use — from the EBI's key-less ChEMBL database, with the year each was first approved, its type and molecular weight. It's free, runs in your browser, and ESC exits.

How the Approved Drug Molecules screensaver works
The saver reads the EBI's ChEMBL database directly in your browser — no key and no account.

ChEMBL and what phase 4 means
ChEMBL is an openly available database from EMBL's European Bioinformatics Institute, which describes it as a manually curated database of bioactive molecules with drug-like properties. It links chemical structures to bioactivity and target information and is widely used in drug discovery research.
In ChEMBL's vocabulary, max phase 4 means the compound is a marketed drug, approved for at least one indication in a given region. This is different from a clinical trial phase 4, which describes studies carried out after approval. The year shown is the first approval ChEMBL records, so a drug sold today may carry a date decades old, and that first approval may have been in a different country than the one you live in.
The molecule type separates familiar small-molecule drugs from antibodies, proteins and other larger kinds. Molecular weight, in daltons, is a size measure: small-molecule drugs are typically a few hundred, while antibodies and proteins weigh far more, so a very large figure usually signals a biologic. The display is a window onto a research database, not prescribing information; it is no substitute for advice from a doctor or pharmacist.

Frequently asked questions
- Is this real data?
- Yes — it comes from the EBI's ChEMBL database and is refreshed on a schedule.
- Is this medical advice?
- No. It is a chemistry database view for interest only. Nothing here is medical advice — talk to a clinician about any medicine.
- Is a key needed?
- No. This source is fully key-less.
- Is it free?
- Yes — free, no download, in your browser.
- What is a dalton?
- It is the unit of molecular mass, roughly the mass of one hydrogen atom. Small-molecule drugs are in the hundreds, while antibodies run to well over a hundred thousand.
- Is every drug that has been approved listed?
- Not necessarily. ChEMBL draws approved-drug information from sources such as the FDA, EMA and WHO ATC, so some products, older formulations or regional approvals may be missing or recorded differently.
- Does an approval year mean the drug is still used?
- No. It records the first approval only, and a drug may have been replaced or withdrawn since.
