What is medicine or drug

When we get sick we take medicine to get well soon. Commonly we call it medicine, and technical peoples call it drug. What is this drug or medicine?

A drug is any substance that causes a change in an organism's physiology or psychology when consumed. In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being.

Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders.

A medication or medicine is a drug taken to cure any symptoms of an illness or medical condition. The use may also be as preventive medicine that has future benefits but does not treat any existing or pre-existing diseases or symptoms. Dispensing of medication is often regulated by governments into three categories- “over the counter” medications, which are available in pharmacies and supermarkets without special restrictions; “behind the counter” medicines, which are dispensed by a pharmacist without needing a doctor's prescription, and “prescription only medicines”, which must be prescribed by a licensed medical professional, usually a physician.

There are many precautions to be taken with medicines. It is important to make sure you take your medicines correctly. Always be guided by your pharmacist or doctor when you are taking any medicine.
