The generic medicines & The brand-name medicines
Drugs sold in different countries have different trade names, also known as brand names, but the names of their active ingredients are the same. They are usually identified by”INN”.
Generic name（or Common name）, also known as international non patent name (INN), is a name recommended by the World Health Organization (WHO).
INN usually refers to the active drug substance, rather than the final drug. A drug has only one generic name, which is more conducive to the communication of professional nursing staff than the trade name.
The generic name of a drug is a name proposed by a new drug developer to the World Health Organization in the process of new drug application. It is approved by the WHO Expert Committee and published in who drug information magazine regularly.
The generic name of a drug is not subject to patent and administrative protection. It is the name of the active ingredient indicated in all documents, materials, teaching materials and drug instructions. The determination of generic names of drugs should follow the principles of who, and should not be the same as existing names or similar to trade names.
Original drug Or brand-name medicines usually refers to the first sales name when the drug was invented.
When a company invents a new drug, it can apply for patent protection.
The patent protection period of a drug is usually 20 years. After deducting the time of drug research and development, animal test and clinical trial, when the drug is officially put on the market for large-scale application, the patent period is usually only 10 years. During this period, the patent holder can monopolize the drug market.
Any generic medicine must perform the same in the body as the brand-name medicine. It must be the same as a brand-name medicine in dosage, form and route of administration, safety, effectiveness, strength, and labeling (with certain limited exceptions). It must also meet the same high standards of quality and manufacturing as the brand-name product, and it must be and quality, taken and used in the same way as well. This standard applies to all generic medicines.
Generic medicines use the same active ingredients as brand-name medicines and work the same way, so they have the same risks and benefits as the brand-name medicines. The DA Generic Drugs Program conducts a rigorous review to ensure generic medicines meet these standards, in addition to conducting inspections of manufacturing plants and monitoring drug safety after the generic medicine has been approved and brought to market.
A generic drug may have certain minor differences from the brand-name product, such as different inactive ingredients.
It is important to note that there will always be a slight, but not medically significant, level of expected variability—just as there is for one batch of brand-name medicine compared with the next batch of brand-name product. This variability can and does occur during manufacturing, for both brand-name and generic medicines. When a medicine, generic or brand-name, is mass produced, very small variations in purity, size, strength, and other parameters are permitted. FDA limits how much variability is acceptable.
For example, a very large research study1 comparing generics with brand-name medicines, found that there were very small differences (approximately 3.5%) in absorption into the body between generic and brand-name medicines. Some generics were absorbed slightly more, some slightly less. This amount of difference is expected and clinically acceptable, whether for one batch of brand-name medicine tested against another batch of the same brand, or for a generic tested against a brand-name medicine.
Generic drugs are approved only after a rigorous review by Drug Administration（DA）per country and after a set period of time that the brand product has been on the market exclusively. This is because new drugs, like other new products, are usually protected by patents that prohibit others from making and selling copies of the same drug.
Generic drugs tend to cost less than their brand-name counterparts because generic drug applicants do not have to repeat animal and clinical (human) studies that were required of the brand-name medicines to demonstrate safety and effectiveness. This abbreviated pathway is why the application is called an “abbreviated new drug application.”
The reduction in upfront research costs means that, although generic medicines have the same therapeutic effect as their branded counterparts, they are typically sold at substantial discounts, an estimated 80 to 85% less, compared with the price of the brand-name medicine（the Original medicines）

If you are unable to locate a generic of your brand-name medicine, it may be that the brand-name medicine is still within the period of time when it has exclusive rights to the marketplace, which allows drug companies to recoup their costs for the initial research and marketing of the brand-name or innovator drug.
Whether you can purchase drugs sold overseas through the Internet for your own use mainly depends on the import laws of your country.
Individuals are usually allowed to import, but limited to a certain amount.
In some cases, when the purchase price on the import application exceeds the allowance, the customer who purchases the goods may have to pay duties or other fees. Customs and tariff rules vary from country to country. For more information, please contact the local customs in your country / region.
Please note that you are responsible for the imported products. Import is the customer’s responsibility. In case of being unable to go through the customs, it needs to be handled by itself.
