Janssen Pharmaceutica
Janssen Pharmaceuticals is a pharmaceutical company headquartered in Beerse, Belgium, and wholly-owned by Johnson & Johnson. It was founded in 1953 by Paul Janssen. In 1961, Janssen Pharmaceuticals was purchased by New Jersey-based American corporation Johnson & Johnson, and became part of Johnson & Johnson Pharmaceutical Research and Development (J&J PRD), now renamed to Janssen Research and Development (JRD), which conducts research and development activities related to a wide range of human medical disorders, including mental illness, neurological disorders, anesthesia and analgesia, gastrointestinal disorders, fungal infection, HIV/AIDS, allergies and cancer. Janssen and Ortho-McNeil Pharmaceutical have been placed in the Ortho-McNeil-Janssen group within Johnson & Johnson Company.

Paul Janssen
Paul Adriaan Jan, Baron Janssen (12 September 1926 - 11 November 2003) was a Belgian physician. He was the founder of Janssen Pharmaceutica, a pharmaceutical company with over 20,000 employees which is now a subsidiary of Johnson & Johnson. Early life and education Paul Janssen was the son of Constant Janssen and Margriet Fleerackers. He attended secondary school at the Jesuit St Jozef college in Turnhout, Belgium after which he decided to follow in his father's footsteps and become a physician. During World War II Janssen studied physics, biology and chemistry at the Facultés universitaires Notre-Dame de la Paix (FUNDP) in Namur. He then studied medicine at the Catholic University of Leuven and Ghent University. In 1951, Janssen received his medical degree ''magna cum laude'' from Ghent University. He graduated with a postdoctoral degree in pharmacology at the same university in 1956, and studied at the Institute of Pharmacology of the University of Cologne. On 16 April 19 ...

Antispasmodic
An antispasmodic (synonym: spasmolytic) is a pharmaceutical drug or other agent that suppresses muscle spasms. Smooth muscle spasm One type of antispasmodics is used for smooth muscle relaxation, especially in tubular organs of the gastrointestinal tract. The effect is to prevent spasms of the stomach, intestine or urinary bladder. Both dicyclomine and hyoscyamine are antispasmodic due to their anticholinergic action. Both of these drugs have general side effects and can worsen gastroesophageal reflux disease. Mebeverine is a musculotropic spasmolytic with a strong and selective action on the smooth muscle spasm of the gastrointestinal tract, particularly of the colon. It does not have the acetylcholine side effect commonly seen in an anticholinergic antispasmodic. Papaverine is an opium alkaloid used to treat visceral spasms, erectile dysfunction and investigated as antipsychotic drug due to its potency to inhibit phosphodiesterase PDE10A. Peppermint oil has been traditio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menstrual Pain
Dysmenorrhea, also known as period pain, painful periods or menstrual cramps, is pain during menstruation. Its usual onset occurs around the time that menstruation begins. Symptoms typically last less than three days. The pain is usually in the pelvis or lower abdomen. Other symptoms may include back pain, diarrhea or nausea. Dysmenorrhea can occur without an underlying problem. Underlying issues that can cause dysmenorrhea include uterine fibroids, adenomyosis, and most commonly, endometriosis. It is more common among those with heavy periods, irregular periods, those whose periods started before twelve years of age and those who have a low body weight. A pelvic exam and ultrasound in individuals who are sexually active may be useful for diagnosis. Conditions that should be ruled out include ectopic pregnancy, pelvic inflammatory disease, interstitial cystitis and chronic pelvic pain. Dysmenorrhea occurs less often in those who exercise regularly and those who have ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acetamides
Acetamide (systematic name: ethanamide) is an organic compound with the formula CH3CONH2. It is the simplest amide derived from acetic acid. It finds some use as a plasticizer and as an industrial solvent. The related compound ''N'',''N''-dimethylacetamide (DMA) is more widely used, but it is not prepared from acetamide. Acetamide can be considered an intermediate between acetone, which has two methyl (CH3) groups either side of the carbonyl (CO), and urea which has two amide (NH2) groups in those locations. Acetamide is also a naturally occurring mineral with the IMA symbol: Ace. Production Laboratory scale Acetamide can be produced in the laboratory from ammonium acetate by dehydration: : H4CH3CO2] → CH3C(O)NH2 + H2O Alternatively acetamide can be obtained in excellent yield via ammonolysis of acetylacetone under conditions commonly used in reductive amination. It can also be made from anhydrous acetic acid, acetonitrile and very well dried hydrogen chloride gas, usin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenol Ethers
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at ...
