Generic drug
A generic drug is a pharmaceutical drug that contains the same chemical substance as a proprietary drug that was originally protected by chemical patents. Generic drugs are allowed for sale after the patents on the original drugs expire. Because the active chemical substance is the same, the medical profile of generics is equivalent in performance compared to their performance at the time when they were patented drugs. A generic drug has the same active pharmaceutical ingredient (API) as the original, but it may differ in some characteristics such as the manufacturing process, formulation, excipients, color, taste, and packaging.
Although they may not be associated with a particular company, generic drugs are usually subject to government regulations in the countries in which they are dispensed. They are labeled with the name of the manufacturer and a generic non-proprietary name such as the United States Adopted Name (USAN) or International Nonproprietary Name (INN) of the drug. A generic drug must contain the same active ingredients as the original brand-name formulation. The U.S. Food and Drug Administration (FDA) requires generics to be identical to or within an acceptable bioequivalent range of their brand-name counterparts, with respect to pharmacokinetic and pharmacodynamic properties.
Biopharmaceuticals, such as monoclonal antibodies, differ biologically from small-molecule drugs. Biosimilars have active pharmaceutical ingredients that are almost identical to the original product and are typically regulated under an extended set of rules, but they are not the same as generic drugs as the active ingredients are not the same as those of their reference products. In most cases, generic products become available after the patent protections afforded to the drug's original developer expire. Once generic drugs enter the market, competition often leads to substantially lower prices for both the original brand-name product and its generic equivalents. In most countries, patents give 20 years of protection. However, many countries and regions, such as the European Union and the United States, may grant up to five years of additional protection ("patent term restoration") if manufacturers meet specific goals, such as conducting clinical trials for pediatric patients.
Manufacturers, wholesalers, insurers, and drugstores can all increase prices at various stages of production and distribution. In 2014, according to an analysis by the Generic Pharmaceutical Association, generic drugs accounted for 88 percent of the 4.3 billion prescriptions filled in the United States. "Branded generics" on the other hand are defined by the FDA and National Health Service as "products that are (a) either novel dosage forms of off-patent products produced by a manufacturer that is not the originator of the molecule, or (b) a molecule copy of an off-patent product with a trade name." Since the company making branded generics can spend little on research and development, it is able to spend on marketing alone, thus earning higher profits and driving costs down. For example, the largest revenues of Ranbaxy, now owned by Sun Pharma, came from branded generics.
Generic drug names are constructed using standardized affixes that distinguish drugs between and within classes and suggest their action.[citation needed]
When a pharmaceutical company first markets a drug, it is usually under a patent that, until it expires, the company can use to exclude competitors by suing them for patent infringement. Pharmaceutical companies that develop new drugs generally only invest in drug candidates with strong patent protection as a strategy to recoup their costs of drug development (including the costs of the drug candidates that fail) and to make a profit. The average cost to a brand-name company of discovering, testing, and obtaining regulatory approval for a new drug, with a new chemical entity, was estimated to be as much as US$800 million in 2003 and US$2.6 billion in 2014. Drug companies that bring new products have several product line extension strategies they use to extend their exclusivity, some of which are seen as gaming the system and labeled "evergreening" by critics, but at some point there is no patent protection available. For as long as a drug patent lasts, a brand-name company enjoys a period of market exclusivity, or monopoly, in which the company is able to set the price of the drug at a level that maximizes profit. This profit often greatly exceeds the development and production costs of the drug, allowing the company to offset the cost of research and development of other drugs that are not profitable or do not pass clinical trials. The impact of loss of patent exclusivity on pharmaceutical products varies significantly across different product classes (e.g., biologics vs. small molecules), largely due to regulatory, legal and manufacturing hurdles associated with such products. Indeed, the greater degree of 'brand-brand' competitive dynamics seen in the biologics and complex generics space allows manufacturers of originators to better protect market share following loss of patent exclusivity.
Large pharmaceutical companies often spend millions protecting their patents from generic competition. Apart from litigation, they may reformulate a drug or license a subsidiary (or another company) to sell generics under the original patent. Generics sold under license from the patent holder are known as authorized generics. Generic drugs are usually sold for significantly lower prices than their branded equivalents and at lower profit margins. One reason for this is that competition increases among producers when a drug is no longer protected by patents. Generic companies incur fewer costs in creating generic drugs—only the cost of manufacturing, without the costs of drug discovery and drug development—and are therefore able to maintain profitability at a lower price. The prices are often low enough for users in less-prosperous countries to afford them.[citation needed] Generic drug companies may also receive the benefit of the previous marketing efforts of the brand-name company, including advertising, presentations by drug representatives, and distribution of free samples. Many drugs introduced by generic manufacturers have already been on the market for a decade or more and may already be well known to patients and providers, although often under their branded name.[citation needed]
India is a leading country in the world's generic drugs market, exporting US$20.0 billion worth of drugs in the 2019–20 (April–March) year. India exports generic drugs to the United States and the European Union. Also according to the market research community the Global Generic Drugs Market was evaluated US$465.96 million in 2021 and is expected to rise with a CAGR of 5.5% from 2022–2028 during the forecast period. In the United Kingdom, generic drug pricing is controlled by the government's reimbursement rate. The price paid by pharmacists and doctors is determined mainly by the number of license holders, the sales value of the original brand, and the ease of manufacture. A typical price decay graph will show a "scalloped" curve, which usually starts at the brand-name price on the day of generic launch and then falls as competition intensifies. After some years, the graph typically flattens out at approximately 20% of the original brand price. In about 20% of cases, the price "bounces": Some license holders withdraw from the market when the selling price dips below their cost of goods, and the price then rises for a while until the license holders re-enter the market with new stock. The NHS spent about £4.3 billion on generic medicines in 2016–17. In 2012, 84 percent of prescriptions in the US were filled with generic drugs, and in 2014, the use of generic drugs in the United States led to US$254 billion in health care savings.
