International drug better than drugs produced in Thailand or not.

International drug better than drugs produced in Thailand or not. Currently, the number of patients is not less popular to buy or use only drugs manufactured overseas rather than domestically produced drugs.
 First of all, I do understand that the first drug produced from two different countries, meaning the drug master (original), a drug development pharmaceutical company in a foreign country for use in medical treatment. And drug production from foreign countries without the underlying drug.
Even in the U.S., UK or Japan have produced drugs that are not in their original medication.
So said the drugs produced by foreign effective than drugs manufactured in Thailand are not always accurate. Thai drug itself and the standard of production is the same with other countries and international standards than in many countries.
However, the underlying drug is a drug developed by pharmaceutical companies through foreign investment and markets both directly and indirectly result in a distribution and it's causing a belief that medication is necessary to use more existing medicines and better medicines from Thailand Especially the claim that raw materials from abroad.
Important issues underlying these drugs will make the patent on all countries to develop a formula for the district to drug production and disposal.
Drug treatment requires multiple patents expire. It is made to each company to continue production and raw materials often come from the same source.
However, these drugs produce the Office of the Food and Drug Administration requirements to multiple drugs to give consumers the confidence to test the biological effectiveness of a drug that is not different from the original drug refers to the same dose group. sample healthy volunteer drug effective in the treatment did not differ.
It may be true that what the drugs, some may be process-specific, which may be medicine for the treatment or absorbed faster, but the final amount of drug in plasma with action, not significantly different within the time prescribed.
Therefore say that if drugs were not different biological effectiveness of the treatment will not differ.
However, the practice is patients with chronic use of drugs that can control the symptoms usually do not change back and forth based pharmaceutical company.
