Drug

From DrugPedia: A Wikipedia for Drug discovery

A drug, broadly speaking, is any chemical substance that, when absorbed into the body of a living organism, alters normal bodily function. There is no single, precise definition, as there are different meanings in medicine, government regulations, and colloquial usage.

Types of Drugs

• Prescription Drug

A prescription drug is a licensed medicine that is regulated by legislation to require a prescription before it can be obtained. The term is used to distinguish it from over-the-counter drugs which can be obtained without a prescription. Different jurisdictions have different definitions of what constitutes a prescription drug.

• Non-Prescription Drug

A prescription drug is sold legally without a physician's prescription; over-the-counter.

• Lifestyle Drug

A lifestyle drug is a medication designed to improve the patient's quality of life by addressing relatively minor and non-life threatening conditions such as baldness, impotence, wrinkles, and obesity. Antidepressants are also sometimes called lifestyle drugs.
