Preclinical stage
The substance is studied in the lab to get a first idea of how it works and how safe it is. Only then can research move on to people.
How it works
Methods and approaches
Behind every package is a chain of stages, and at each one someone is responsible for their part: researchers for the data, experts for the registration decision, the manufacturer for quality, the pharmacy for proper storage and dispensing. Here those stages are described in order, without product names or medical detail.
No stage can stand in for another. Good trial results mean nothing if the packages then spent a month in a hot truck with no monitoring.
How this section works: we explain the general sequence by which a medicine is created, checked and brought to the patient, relying only on verified information. We do not discuss timelines, dosing regimens or treatment decisions — that is the doctor's job.
Development
Before a medicine is approved for use, it is studied step by step — first without people, then with them.
Registration and oversight
The government authorises a medicine's circulation and oversees how it is made and sold.
The State Register
Medicines registered in Russia are listed in the State Register of Medicines kept by the Russian Ministry of Health, and you can look up an entry yourself. Other countries have their own registers.
Market oversight
In Russia, Roszdravnadzor oversees the circulation of medicines and inspects pharmacies. Its public registers help confirm that a seller is entitled to trade.
Package leaflet
The official instructions for medical use are an official document, but they are meant to be read together with your doctor's prescription, not instead of it.
Manufacturing and storage
Quality is built in at the factory and preserved in the warehouse, in transit and at the pharmacy.
Batch release
Medicines are made in batches; the batch number on the package lets you trace when and where it was produced.
Storage conditions
For many medicines, temperature, humidity and protection from light matter. Breaking these conditions in transit can spoil even a genuine product.
Labelling
The information on a package helps trace its origin. A package without clear labelling, or with text covered up, is a reason to ask a pharmacist.
The stages of the journey in one table
| Stage | Key question | Who is responsible |
|---|---|---|
| Preclinical research | Is it worth moving on to trials in people? | Researchers and laboratories |
| Phase I–III clinical trials | Is the medicine safe, and does it work? | Research centres, doctors, ethics committees |
| Registration | Can it be authorised for use in the country? | Government experts (in Russia, the Ministry of Health) |
| Manufacturing and transport | Does every batch meet the requirements? | Manufacturer and distributor |
| Pharmacy and monitoring | Is it stored and dispensed correctly, and how does it behave in practice? | Pharmacy, doctors, the regulator (in Russia, Roszdravnadzor) |

Information is current as of the preparation date. Rules for registering medicines and selling them at a distance change from time to time, so check the official registers — in Russia, those of the Ministry of Health and Roszdravnadzor; elsewhere, your national medicines regulator — and ask a doctor or pharmacist about treatment.
