Preparation H
Preparation H is an American brand of medications that is made by Pfizer, used in the treatment of hemorrhoids. Hemorrhoids are caused at least in part by inflamed blood vessels, and most versions of Preparation H work by reducing inflammation in blood vessels. The company that makes this product incorporated in 1926 as American Home Products (AHP) and "one of AHP's earliest prizes was the acquisition of a sunburn oil in 1935 that the company transformed into Preparation H, which became one of the world's best-selling hemorrhoid treatments." AHP changed its name to Wyeth in 2002, and was then bought by Pfizer in 2009, which was reported to have paid $68 billion. Formulations Several formulations have been produced. Some are in a water-based gel while others are petroleum jelly-based, and the suppositories use a base of cocoa butter. It also comes as a medicated wipe. The active ingredients range from simple caffeine moisturizers with witch-hazel astringent to preparations contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yeast Extract
Yeast extracts consist of the cell contents of yeast without the cell walls; they are used as food additives or flavorings, or as nutrients for bacterial culture Growing media, media. They are often used to create savoury flavors and umami taste sensations and can be found in a large variety of packaged foods including frozen meals, crackers, snack foods, gravy, stock and more. They are rich in B vitamins (but not Vitamin B12, B12). Yeast extracts and Fermentation in food processing, fermented foods contain glutamic acid (free glutamates), an amino acid which adds an umami flavor. Glutamic acid is found in meat, cheese, fungi (mushrooms and yeast) and vegetables—such as broccoli and tomatoes. A number of other substances found in yeast extract provide aromas, some meat-like, when allowed to react under heat. The heat-autolytic process to make yeast extract of the autolysate type was invented in the 19th century by Justus von Liebig. Yeast cells are heated until they rupture, t ...

Drugs Developed By Pfizer
A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect. Consumption of drugs can be via inhalation, injection, smoking, ingestion, absorption via a patch on the skin, suppository, or dissolution under the tongue. In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders. Classification Pharmaceutical drugs are often classified into drug classes—groups of related drugs that have sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mass Fraction (chemistry)
In chemistry, the mass fraction of a substance within a mixture is the ratio w_i (alternatively denoted Y_i) of the mass m_i of that substance to the total mass m_\text of the mixture. Expressed as a formula, the mass fraction is: : w_i = \frac . Because the individual masses of the ingredients of a mixture sum to m_\text, their mass fractions sum to unity: : \sum_^ w_i = 1. Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called ''percentage by weight'', abbreviated ''wt.%'' or ''% w/w''; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size; mole fraction (percentage by moles, mol%) and volume fraction ( percentage by volume, vol%) are others. When the prevalences of interest are those of individual chemical elements, rather than of compounds or other substances, the term ''mass fraction'' can also refer to the ratio of the mass of an element to the tot ...

George Sperti
George Speri Sperti (January 17, 1900, Covington, Kentucky – April 29, 1991, Cincinnati, Ohio) was an Italian-American who invented Preparation H hemorrhoid medication. He also invented the Sperti Ultraviolet Lamp, Aspercreme for pain relief, and KVa Power Meter. Sperti graduated from the University of Cincinnati in 1923. Shortly afterwards he was named Director of its Research Laboratory. His invention of an ultraviolet lamp to irradiate milk and add Vitamin D without changing the flavor was sold to General Foods for US$300,000. Sperti donated the entire amount to the University to continue basic research, and went on to develop a successful business line of ultraviolet sunlamps. He also invented the first practical technique for freeze-drying orange juice concentrate. He donated most of the money he received from 127 patents to the University of Cincinnati and the Institutum Divi Thomae, which he co-founded in 1935 in collaboration with the Archdiocese of Cincinnati, with ...

Hemorrhoid
Hemorrhoids (or haemorrhoids), also known as piles, are vascular structures in the anal canal. In their normal state, they are cushions that help with stool control. They become a disease when swollen or inflamed; the unqualified term ''hemorrhoid'' is often used to refer to the disease. The signs and symptoms of hemorrhoids depend on the type present. Internal hemorrhoids often result in painless, bright red rectal bleeding when defecating. External hemorrhoids often result in pain and swelling in the area of the anus. If bleeding occurs, it is usually darker. Symptoms frequently get better after a few days. A skin tag may remain after the healing of an external hemorrhoid. While the exact cause of hemorrhoids remains unknown, a number of factors that increase pressure in the abdomen are believed to be involved. This may include constipation, diarrhea, and sitting on the toilet for long periods. Hemorrhoids are also more common during pregnancy. Diagnosis is made by lo ...

Hydrocortisone
Hydrocortisone is the name for the hormone cortisol when supplied as a medication. It is a corticosteroid and works as an anti-inflammatory and by immune suppression. Uses include conditions such as adrenocortical insufficiency, adrenogenital syndrome, high blood calcium, thyroiditis, rheumatoid arthritis, dermatitis, asthma, and COPD. It is the treatment of choice for adrenocortical insufficiency. It can be given by mouth, topically, rectally or by injection. Stopping treatment after long-term use should be done slowly. Common side effects may include mood changes, increased appetite, hyperglycemia, hypertension, and edema (swelling). With long-term use, common side effects include osteoporosis, adrenal insufficiency, upset stomach, physical weakness, easy bruising, and candidiasis (yeast infections). It is unclear if it is safe for use during pregnancy. Hydrocortisone was patented in 1936 and approved for medical use in 1941. It is on the World Health Orga ...

Pramoxine
Pramocaine (INN and BAN, also known as pramoxine or pramoxine HCl) is a topical anesthetic discovered at Abbott Laboratories in 1953 and used as an antipruritic. During research and development, pramocaine hydrochloride stood out among a series of alkoxy aryl alkamine ethers as an especially good topical local anesthetic agent. Pharmacologic study revealed it to be potent and of low acute and subacute toxicity, well tolerated by most mucous membranes and of a low sensitizing index in humans. Like other local anesthetics, pramocaine decreases the permeability of neuronal membranes to sodium ions, blocking both initiation and conduction of nerve impulses. Depolarization and repolarization of excitable neural membranes is thus inhibited, leading to numbness. Use Topical anesthetics are used to relieve pain and itching caused by conditions such as sunburn or other minor burns, insect bites or stings, poison ivy, poison oak, poison sumac, and minor cuts and scratches.
