First of all, we must answer the question: how are drugs classified anyways?
Drugs are classified based on their use, characteristics, chemical effects, dangers, and others. By classifyiung drugs, medical professionals will have an easier time prescribing medicine to their patient due to the simple fact that it is already listed in a neat, but long list.
And since they're somewhat related to each other, some medical professionals will also be able to distinguish which medicine to apply in a situation where medical and medicinal supplies are scarce.
