If the drug development and patent protection it is engaged in a large pharmaceutical company, the drug called original.The substance in this case is allocated to it for the first time before this drug no issues.Development of all stages of the drug lasts about 10 years, many clinical trials to test the efficacy and safety.
Doing this kind of work, the company is developing its patent protection period expires after a certain time.Chemical formula becomes aware of competitors that are now legally able to develop it.Details of the process are different each time, and is characterized by the quality of raw materials. leader for the production of analog drugs now - India.
low cost analogue or generics, formed in part because of the fact that it is not wasted time and money on development and research.Can we assume that
the effect of the drug is definitely worse copies of analog?

Analogs jodomarin

analogues of this drug a lot.Here are the most famous of them:
- «Potassium iodide";
- «antistrumin-Darnitsa";

How to choose generics

What else besides the price analogues differ from the original formulation and from each other?Can the effect of different drugs if the chemical formula is identical?

Besides the chemical and pharmaceutical identity, there is also the concept of bioequivalence.This means that all preparations for provision of similar effects on the body should be of similar bioavailability.

called bioavailability relative amount of the substance has got into the blood and the rate of blood flow in getting.Not all of us want to spend time and money to test therapeutic equivalence of drugs.It, unlike pharmaceutical equivalence is not required.That people did not buy so "pig in a poke", the United States set up a special organization dedicated to test therapeutic equivalence of generics.In Russia, nothing like yet, and therefore remains to rely on the experience of others when choosing products. If the patient's condition is critical, it is not necessary to experiment to find the cheapest drugs.
Doctors writing the prescription, are forced to write their recipes according to their own experience and colleagues.It brings in the issue of confusion and constant advertising sales representatives.
