The life of a patent is 17 years in the United States.
The drug will not be able to be patented again. Once the patent runs out, other companies can manufacture it without paying licensing rights.
When a drug company files for patent protection, it must disclose the formula. Once the patent expires, other companies can use the patent disclosure to obtain the formula to produce a generic version of the drug. Most companies that produce generic drugs are specialists in improving the process for manufacturing the drug to make it as cheap as possible. This requires different kinds of research and business skills than manufacturing and obtaining approval for a completely new drug.
Pharmaceutical companies, when designing a drug, obtain a patent so that no other company can manufacture the same drug. This patent typically lasts 17-20 years. After the patent has expired, any other company can manufacture the same drug. This is where generic drugs come in. They are the same active ingredient, dose, dosage form, route of administration, and are tested and shown to be bioequivalent. Thus, drugs that were once on patent can have a generic equivalent that is much less expensive to the consumer but work the same as the brand name drug.
the current patent holder is ASTRA

Patents protect inventors from having their work copied by others. The work to be protected must be original, useful, and not obvious. An example of this is the popular drug Zocor. It was under patent until June, 2006, so no other company could make and sell that drug. The patent expired and now other companies can sell the drug labeled with its generic name, Simvastatin. Once issued, a patent can be used to prevent others from making, using, selling or importing any product or service that infringes any valid claim in the issued patent, but only in countries where the patent is issued and valid.
