Orange B is a food dye from the azo dye group. It is approved by the United States Food and Drug Administration (FDA) for use only in hot dog and sausage casings or surfaces, only up to 150 parts per million of the finished food weight. [1] It is typically prepared as a disodium salt. [1]
Orange B was first listed as an approved food dye by the FDA in 1966. In 1978, the FDA proposed removing it from the list due to concerns about the presence of carcinogenic contaminants (specifically 2-naphthylamine). The only supplier in the United States, the William J. Stange Company, subsequently stopped manufacturing it but it was not removed from the list. [2]
The United States Food and Drug Administration is a federal agency of the Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, caffeine products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, animal foods & feed and veterinary products.
Food coloring, or color additive, is any dye, pigment, or substance that imparts color when it is added to food or drink. They be supplied as liquids, powders, gels, or pastes. Food coloring is used in both commercial food production and domestic cooking. Food colorants are also used in a variety of non-food applications, including cosmetics, pharmaceuticals, home craft projects, and medical devices. Colorings may be natural or artificial/synthetic.
A generic drug is a pharmaceutical drug that contains the same chemical substance as a 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.
The pregnancy category of a medication is an assessment of the risk of fetal injury due to the pharmaceutical, if it is used as directed by the mother during pregnancy. It does not include any risks conferred by pharmaceutical agents or their metabolites in breast milk.
Tegaserod is a 5-HT4 agonist manufactured by Novartis and sold under the names Zelnorm and Zelmac for the management of irritable bowel syndrome and constipation. Approved by the FDA in 2002, it was subsequently removed from the market in 2007 due to FDA concerns about possible adverse cardiovascular effects. Before then, it was the only drug approved by the United States Food and Drug Administration to help relieve the abdominal discomfort, bloating, and constipation associated with irritable bowel syndrome. Its use was also approved to treat chronic idiopathic constipation.
Cefixime, sold under the brand name Suprax among others, is an antibiotic medication used to treat a number of bacterial infections. These infections include otitis media, strep throat, pneumonia, urinary tract infections, gonorrhea, and Lyme disease. For gonorrhea typically only one dose is required. In the United States it is a second-line treatment to ceftriaxone for gonorrhea. It is taken by mouth.
Erythrosine, also known as Red No. 3, is an organoiodine compound, specifically a derivative of fluorone. It is a pink dye which is primarily used for food coloring. It is the disodium salt of 2,4,5,7-tetraiodofluorescein. Its maximum absorbance is at 530 nm in an aqueous solution, and it is subject to photodegradation.
Allura Red AC is a red azo dye that goes by several names, including FD&C Red 40. It is used as a food dye and has the E number E129.
Citrus Red 2, Citrus Red No. 2, C.I. Solvent Red 80, or C.I. 12156 is an artificial dye. As a food dye, it has been permitted by the US Food and Drug Administration (FDA) since 1956 to color the skin of oranges. Citrus Red 2 is listed by the International Agency for Research on Cancer (IARC) as a group 2B carcinogen, a substance "possibly carcinogenic to humans".
Amaranth, FD&C Red No. 2, E123, C.I. Food Red 9, Acid Red 27, Azorubin S, or C.I. 16185 is a modified red azo dye used as a food dye and to color cosmetics. The name was taken from amaranth grain, a plant distinguished by its red color and edible protein-rich seeds.
The Drug Price Competition and Patent Term Restoration Act, informally known as the Hatch-Waxman Act, is a 1984 United States federal law that established the modern system of generic drug regulation in the United States. The Act's two main goals are to facilitate entry of generic drugs into the market and to compensate the original drug developers for regulatory delays by the Food and Drug Administration. It is generally believed that the Act accomplished both goals: encouraging development of new medications and accelerating market entry of generics.
In the field of pharmacy, compounding is preparation of custom medications to fit unique needs of patients that cannot be met with mass-produced products. This may be done, for example, to provide medication in a form easier for a given patient to ingest, or to avoid a non-active ingredient a patient is allergic to, or to provide an exact dose that isn't otherwise available. This kind of patient-specific compounding, according to a prescriber's specifications, is referred to as "traditional" compounding. The nature of patient need for such customization can range from absolute necessity to individual optimality to even preference.
