None, several medicnes are poisons, it is all a question of dosis

In pharmacy drug are also called medicine and are used for bringing or sustaining well-being of a person either by curing, preventions like prophylaxis, diagnosis like barium meal, elevating pains like analgesics and placebo too. A drug may or may not be helpful like in the case of illicit drugs. Pharmaceutically all medicines are drugs. But clinically not all drugs are medicines. Drugs, most of which would be medications that are illegal to produce, own use or sell. Drug is the main chemical component in a medicine. That is why a placebo can not be a drug. When a drug is mixed with other pharmaceutical ingredients, medicine is obtained as a final product.

Thanks you all for such nice information. I have used Sorafenib to cure my animals in my PhD Research, should a write sorafenib as medicine or drug.

Dear Shazia Kanwal Malik

In your case you can use a term "drug", because it is already formulated biologically active substance.

In fact, the terms “drug” and “medicine” are often mistakenly used as two similar terms. However, in the strictest sense, the two have different meanings or definitions, and they can serve different purposes. http://www.differencebetween.net/language/words-language/difference-between-drug-and-medicine/#ixzz5Cuesnwfj

Thank you sir.

The previous answers are quite clear. If you still have any doubts I suggest you read the following article:

Article Clarification of Terminology in Drug Safety

not much only the vision of use.

I think Tanwir Athar

Medicine is a substance or preparation used in treating disease, while drug is any chemical compound either synthesized in laboratory or of plant, animal or marine origin which is intended to bring change in normal physiological functions of body. All medicines are drugs but all drugs are not medicines.

Medicines generally are not addictive in nature, unlike drugs. Medicines are made for the treatment of a particular disease, while drug is often considered as narcotic, a stimulant or hallucinogen. Medicines never cause stupefaction while drugs do. However, excessive use of medicines are harmful and can cause negative affects like drugs.
