What is the difference between generic and patent medicine?
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.

Where did manufacturers get the formula of patent drug to produce generic durg?
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.
Why is it taking so excessively long for Viagra to become a generic drug?
I believe that with any drug, the company that did all the research and development (usually 10 or so years) to make the drug wants to recoup their investment. Thus they have a patent for a lengthy period of time so that only that one company can manufacture the drug. Once the patent expires then one of two things happens: they can revise the drug and get another patent, or release the drug so that any company can make it. Since all the research and development is already done, those companies can make it much cheaper - they just can't make or market it by its original name (in this case Viagra) - it has to be marketed under its generic name. When you see the symbol "R" enclosed in a circle after the name, that is an indication that is the original trade name. Generics do not have that symbol.
