Search for the cheapest drug analogues in the active substance

To save money on the purchase of medicines, it is necessary to clearly understand that it is necessary to search. To do this, you need to understand the terminology and that the doctor writes a prescription.

This is very important because the confusion of terms can lead to the fact that you choose the result is not the drug that you wrote the doctor.

Patients often seek similar expensive cheap drugs without understanding the meaning of the terms "analogue", "synonym", "generic". So before you start looking for a cheap drug, we shall understand terminology.

What doctor writes in a prescription?

Doctors should not prescribe medication by a commercial name, that is, certain producers who could pay physicians for this service. Now, doctors are required to specify in the prescription active ingredient, according to which the patient can choose the drug available in the pharmacy trade names.

International nonproprietary name

International nonproprietary name - a unique name of the active ingredient of the drug. In each drug is bound to have one or more active ingredients and may be a few more additional substances and excipients. It is the main active ingredients have a therapeutic effect on a certain disease. Here is the active ingredient and the physician must indicate in the recipe.

Original (branded) medicine

In addition to developing the formula of the active substance is necessary to determine its efficacy and side effects, starting with tests on cells, mice and ending with volunteers to develop the technology of its production, to carry out a costly advertising campaign. The average term of a patent is about 25 years, and the remaining 10-15 years, the manufacturer has to recoup their development costs and time to market of the original drugs and make a profit, so the cost of patented drugs is very high, but the quality is guaranteed.


This term may apply with respect to physicians generics. Therefore, everything that is written about generic applies to aliases. If your doctor told you to use the term "synonymous", ask him whether he has in mind in this case the generic or investing in the term "synonymous with" some other meaning.

Analog or similar medicines

Since this term is most often associated confusion in concepts. Sometimes this term is incorrectly used to refer to generics, and this is a serious mistake. Similar to the original medicine - is often not generic. A similar drug (analog) often contains completely different active ingredient. Usually refers to analogs medicines that belong to one group, for example, antihistamines, and this is completely different in the active substance medications and the patient they have not quite the same effect.
