he drugs; one which is called the Anatomical Therapeutic Chemical Classification System or ATC. In this system, there are five different classifications used.
At the beginning Marc Staal Womens Jersey , the drugs are divided into classifications that are based on the parts of the body that these focus on. An example for this is that Code A drugs are meant for metabolism and the alimentary tract while the drugs that focus on the blood as well as the organs related to it is classified as Code B. On the other hand, Code C drugs are those that make an effect on the cardiovascular system as well as the respiratory and nervous systems and also the sensory organs.
At the second level, a two-digit code is added to the letter to identify the main therapeutic group. The third level adds another letter to indicate the therapeutic subgroup. The fourth level adds yet another level to show another subgroup and finally the fifth level, which is another two-digit code, identifies the chemical substance used in the specific drug. So a doctor or pharmacist could look at this code and know for what this drug is meant to be used.
