How a medicine is created
From lab experiments to three phases of clinical trials in people — why development takes so long.
the journey of a medicine: from the lab to the pharmacy
The journey of a medicine: from the lab to the pharmacy
A tablet or vial at the pharmacy is the last stop on a long road. Before a medicine reaches a patient, it is studied for years, tested on volunteers, reviewed by government experts, and then manufactured and transported under strict rules. We explain how that journey works and help you avoid detours to random sellers.
A medicine is valuable not only for what it contains but for the whole history of checks behind it. A package that came from who knows where has no such history, even if it looks exactly like the real thing.
Four stages of the journey
Registration and registers
What government registration means, who keeps the register of medicines and how to find an entry in it yourself.
Originator and generic
Why one active substance can come in several packages from different manufacturers, and what confirms they are equivalent.
Where to buy safely
How to tell a licensed pharmacy from a "supplier" website, and why a medicine bought from a stranger can be dangerous.

Checking an online pharmacy in five steps
Company details and licence
A real pharmacy's website shows the organisation's legal name, its address and licence details. If all you see is an order form and a messenger number, that is a reason to stop.
Check the register
In Russia, look the organisation up in Roszdravnadzor's public registers, and check the medicine itself in the State Register of Medicines kept by the Russian Ministry of Health. Other countries have their own regulators — use the official one where you live.
Prescription means prescription
A legitimate seller will not dispense a prescription-only medicine without a prescription. An offer to "skip the paperwork" is not a sign of care — it shows the rules are not followed here.
Receipt and delivery
A reputable pharmacy gives you a receipt and explains how storage conditions are maintained on the way to you. Shipping in a plain envelope or a hand-off at a metro station should raise suspicion.
A "miracle substitute"
Talk of a product that "works the same but costs far less", or of a secret channel from abroad, is a warning sign. Only a doctor decides on any change to prescribed treatment.
The essentials in brief
Are you a pharmacy or a manufacturer?
No. We sell nothing, take no orders and represent no company. Tongmengpharm is a reference that explains how the journey of a medicine works and how to check a seller.
Can you suggest an alternative or a price?
No. We do not suggest substitutes, compare packages or publish prices. Whether one medicine can be swapped for another is up to your doctor, and a pharmacist can tell you about the options available within your prescription.
Can I order a medicine from a "supplier" abroad?
Such purchases are risky: nobody has checked authenticity or storage conditions, and returning or verifying the product is almost impossible. If the treatment you need is hard to find, ask your doctor which legal routes exist in your situation; the procedure is set by law.
How do I get into a clinical trial?
Only through your doctor. They know your condition, can find out about suitable trials and explain what taking part offers and what the risks are. Do not trust websites that promise a "place in a programme" for money.
About the project
This domain used to host an online storefront that sold medicines, and later its old addresses were used for advertising links. The current reference has no connection to it: it has different authors and different aims, and it neither sells nor recommends medicines.
We write about the journey itself — research, registration, manufacturing, storage and legal sale. Medicine names, regimens and prices are deliberately absent: those questions are for a doctor and pharmacist who know the individual person.

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.
