Drugs often have two names: a generic name and a brand name. While this is a common practice, many people may not understand why drugs have two names and why it matters. In this article, we will explore the science behind why drugs have two names and why it is important to understand the difference between them.

Why Are Drugs Given Two Names?

Drugs have two names for a variety of reasons. The first name is usually the chemical name, or the name given to the drug by the manufacturer. This name is typically used in a scientific context and is not necessarily easy to remember or pronounce. The second name is the common name, or the name given to the drug by the public. This name is often used by physicians and pharmacists when prescribing or dispensing the drug.

The two names of a drug can also be used to differentiate between two similar drugs. For example, two drugs used to treat the same condition may have similar chemical names, but different common names. This can help to ensure that the right drug is prescribed and dispensed to the patient.

The two names of a drug can also be used to distinguish between different forms of the drug. For example, a drug may be available in both oral and injectable forms, and each form may have a different name. This helps to ensure that the correct form of the drug is prescribed and dispensed.

The Benefits of Using Two Names for Drugs

Using two names for drugs can be beneficial for both physicians and patients. The chemical name allows for a clear understanding of the drug’s chemical makeup and properties, which can help to ensure that the correct drug is prescribed and dispensed. The common name allows for easy communication between health care professionals and patients, which can help to ensure that the correct drug is prescribed and dispensed.

Using two names for drugs can also help to ensure that the correct dosage is prescribed and dispensed. For example, one drug may have different doses available, and each dose may have a different name. This can help to ensure that the right dose is prescribed and dispensed.

The Disadvantages of Using Two Names for Drugs

Using two names for drugs can be confusing for both physicians and patients. It is difficult to remember both the chemical and common names of a drug, and it can be confusing to try to keep track of multiple drugs with similar names.

Using two names for drugs can also lead to errors if the wrong name is used. For example, if a physician presribes a drug by its common name but the pharmacist dispenses it by its chemical name, the wrong drug may be dispensed. This can lead to serious medical consequences.

Are There Regulations for Drug Naming?

The International Nonproprietary Name (INN) system is a system of regulations that sets standards for drug naming. This system sets out guidelines for naming new drugs and also provides a list of existing drugs, along with their chemical and common names. The INN system is overseen by the World Health Organization and is used to ensure that drugs are named consistently throughout the world.

What Are the Benefits of the INN System?

The INN system provides several benefits. First, it helps to ensure that drugs are named consistently throughout the world. This helps to ensure that the same drug is prescribed and dispensed regardless of where it is purchased. Second, it helps to reduce confusion by providing a standardized list of drugs, along with their chemical and common names. Finally, it helps to reduce errors by ensuring that the right drug is prescribed and dispensed.

What Are the Disadvantages of the INN System?

The INN system does have some drawbacks. First, it is difficult to keep up with the rapidly changing field of medicine, and the list of drugs provided by the INN system may not always be up to date. Second, some countries may not adhere to the INN system, and drugs may be given different names in different countries. Finally, the INN system does not cover all drugs, and some drugs may not have an official common name.

Generic names are the scientific name given to drugs, while brand names are the names given by companies who manufacture drugs.
