Generic medicines are preferred by some people because they are usually less expensive, yet they have the same ingredients as brand name medicines. If the generic medicine has the same ingredients, this means that the medicine should have the same effect on the person as the brand name medicine. If the ingredients in the generic and the brand name medicines are a little different, then the generic type cannot claim to be the same as the brand name medicine.
Generic medicines are almost always cheaper than brand name medicines. Why is this? Making any kind of medicine takes a lot of money and a lot of time. This is because a company has to pay doctors and scientists to study an illness and to find some kind of medicine to fight this illness. Then, it takes more money and more time for the company to test the medicine to make sure it is safe and that it works. Once a company is ready to sell its product to people, the company usually sets the price of the medicine very high. The company charges a lot of money in order to get back all of the money that it spent making the medicine. Generic medicine makers, on the other hand, copy some kind of medicine that has already been developed and tested. For this reason, they do not have to spend as much money to develop the medicine.
