What is the relationship among drugs, drugs, pharmaceutical preparations and pharmaceutical dosage forms?

Drugs are officially approved by the state, with the approval number, and can be marketed; Drugs are the names of drugs before national approval. For example, when we do clinical trials, they are all called "drug clinical trials", not drug clinical trials. When we write the plan, we all call it drugs, experimental drugs, control drugs, drug sources, drug storage and drug distribution.

Any drug must be made into a safe, effective and stable dosage form suitable for patients before clinical trials, that is, drug dosage form. Specific drugs in various dosage forms are called pharmaceutical preparations.
