Biopharmaceuticals pose a challenge in the naming of non-proprietary products because, unlike smaller molecules produced by total synthesis or semi-synthesis, there is less certainty for complete fungibility between products from different manufacturers. Just as wine can vary depending on the yeast strain and the year of harvest, each can be subtly different as living organisms are an integral part of production. The WHO MedNet community is continuously working to expand its biopharmaceutical system to ensure that nonproprietary name objectives continue to be met. [6] In recent years, the development of the biological qualification system has been an example. [6] If one were to break down the name of the drug solanezumab, it would be divided into two parts as follows: Solane-Zumab. -Zumab is the suffix for humanized monoclonal antibodies. [9] By definition, monoclonal antibodies contain only one antibody clone and have binding specificity for a given epitope. [15] In the case of solanezumab, the antibody is designed to bind to amyloid β peptides that make up the protein plaques on the neurons of people with Alzheimer`s disease. If a new drug is discovered, the company that discovered it would ask for permeability to prevent other companies from manufacturing and selling the drug. This consistency can last up to 20 years and during this time, the company will produce and sell the drug under a brand name to recoup its investment and make a profit. Over time, this name becomes synonymous with the drug. But after the patrol expires, other companies are allowed to make a similar drug.
This is what has led to brand and generic names in drugs. Today, national nonproprietary names are generally the same as those of the INN. Generic names usually indicate via their strains to which class of active ingredients the drug belongs. [4] For example, acyclovir can be said to be an antiviral drug because its name ends with the suffix -vir. In 1953, WHO created the System of International Nonproprietary Names (INN), which produces INNs in various languages, including Latin, English, French, Spanish, Russian, Chinese and Arabic. Several countries also have systems at the national level for creating generic names, including the British Approved Name (BAN) system, the Australian Approved Name (AAN) system, the USA Adopted Name (USAN) system (which is largely identical to the United States Pharmacopoeia (USP) system), and the Japanese Accepted Name System (JAN). At least some of these national systems of approved names/aliases/accepted names were not created until the 1960s, after the INN system had already existed. In the 21st century, increasing globalization favors maximum rationalization of new generic names for drugs, and it is increasingly expected that the new USAN, BAN and JAN will not differ from the new INNs without special justification. Valid exceptions to the general pattern occur when a common name begins a sentence (and therefore takes a capital letter), when a common name has a headdress (e.g., GoLYTELY, MiraLAX), or when big man letters are used in common names to avoid confusion between similar names (e.g., predniSONE and predniSOLONE). If your prescription is for a brand name, but your doctor allows generic substitution, the drug label will list the active ingredient. Despite the differences between brand names and generics, the active ingredients are effectively the same.
However, talking to your doctor before filling out your medication list will ensure that you get the right medication. You shouldn`t assume that a drug is the same just by looking; It takes an understanding of the composition of the drug to decide. Chemical names are scientific names, based on the molecular structure of the drug. There are different systems of chemical nomenclature and therefore different chemical names for a substance. The most important is the name IUPAC. Chemical names are usually very long and too complex to be commonly used in relation to a drug in speech or prose materials. [1] For example, „1-(isopropylamino)-3-(1-naphthalenyloxy)propan-2-ol” is a chemical name for propranolol. Sometimes a company developing a drug may give the drug a company code[3] that is used to identify the drug during its development. For example, CDP870 was UCB`s corporate code for certolizumab Pegol; UCB then chose „Cimzia” as its trade name.
[1] Many, but not all, of these codes have prefixes that correspond to the company name. During development, the company will seek regulatory approval of the drug from the relevant national regulatory authority, such as the U.S. Food and Drug Administration (FDA). and it will apply to a generic (non-exclusive) name for that country, such as the name adopted by the United States (USAN) or the Japanese accepted name (JAN). It will also apply for an International Nonproprietary Name (INN) from the World Health Organization (WHO). In the UK, strict quality controls are in place before a product licence is granted for branded (commercial) or generic versions of medicines. This means that a generic or branded version of the same drug is of the same quality and has the same effect. Generic drugs marketed without a brand name are cheaper than brand-name drugs, even though they are chemically identical to brand-name drugs and meet U.S. Food and Drug Administration (FDA) standards for safety, purity and potency. In the first half of the 20th century, generic names of drugs were often invented by grouping chemical names into fewer syllables.
This contraction was partially, unofficially, locally normalized, but it was not universally consistent. In the second half of the 20th century. In the nineteenth century, nomenclatural systems moved away from this contraction to the current system of strains and affixes that show chemical relationships. The first roots of generic drug name standardization began with urban pharmacopoeias such as the pharmacopoeias of London, Edinburgh, Dublin, Hamburg and Berlin. Fundamental advances in chemistry in the 19th century made this era the first time, in which what we now call chemical nomenclature, a vast plethora of names based on atoms, functional groups and molecules, was necessary or conceivable. In the second half of the 19th century and the beginning of the 20th century. In the nineteenth century, city pharmacopoeias were combined into national pharmacopoeias (such as the British Pharmacopoeia, the United States Pharmacopoeia, the Germanic Pharmacopoeia (PhG or PG), the Italian Pharmacopoeia and the Japanese Pharmacopoeia) and national formulas (such as the British National Formulary, the Australian Pharmaceutical Formulary and the National Formulary of India). International pharmacopoeias such as the European Pharmacopoeia and the International Pharmacopoeia of the World Health Organization (WHO) constituted the next level. „Diazepam” is an example of the chemical (generic) name of a sedative.
It is marketed by some companies under its generic name and by other companies under brand names such as Valium or Vazepam. For example, the 2015 publication guidelines of the American Society of Hematology (ASH) state,[5] „Generic (generic/scientific) names should be used and should be lowercase.” [5]. „The first letter of the name of a patented medicine must be capitalized.” [5]. „If necessary, you can insert a brand name in parentheses right after the generic name after its first mention.” [5] For combination drugs – those that have two or more drugs combined in a single dosage form – there are individual common names starting with „co-„, both in the form of the UK Approved Name (BAN) and in a previously retained USP name called the Pharmacy Equivalent Name (PEN). Otherwise, both names are simply given to both, joined by hyphens or slashes. For example, suspensions that combine trimethoprim and sulfamethoxazole are called trimethoprim/sulfamethoxazole or co-trimoxazole. Similarly, co-codamol is codeine paracetamol (acetaminophen) and co-triamtercide is triamterene hydrochlorothiazide. The USP has stopped maintaining the NEPs, but similar prohibitions prefixed „co” are still in place. These differences are noticeable between generics and generics, as well as between generics. This means that you are given different names of drugs with the same active ingredients, and this active ingredient refers to the generic drug. Generic name, drug: The term „generic name” has several meanings when it comes to drugs: Drug nomenclature is the systematic naming of drugs, especially drugs.
In most cases, drugs have 3 types of names: chemical names, the most important of which is the IUPAC name; generic or common names, the most important of which are International Nonproprietary Names (INNs); and trade names, which are brand names. [1] The generic names of today`s drugs are constructed from affixes and strains that divide drugs into different categories and also separate drugs within categories. [2] A marketed drug may also have a company code or a compound code. [3] Some drugs are sold both in generic and branded form. When several companies market a drug, it has several different brand names. Prefixes and infixes have no pharmacological significance and are used to separate the drug from other drugs of the same class. Suffixes or strains can be found in the middle or more commonly at the end of the drug name and usually indicate the effect of the drug. Generic names often have suffixes that define the class of the drug. [2] Some tablets or pills contain a combination of medications.
Combination products are often marketed and sold with a brand name. However, the individual ingredients (individual drugs combined in a tablet or pill) are all listed in small print on the packaging.
