Glucocorticosteroids drugs

There is also data showing that antibiotics are helpful during preterm labor for women who carry bacteria called group B streptococcus (GBS). About one in five women will carry GBS, and babies who get infected during labor and delivery can become very sick. Antibiotics can treat GBS and reduce complications of a subsequent infection in the newborn, but carry risks for the mother ( Ohlssen & Shah, 2009 ). Most care providers test women for the bacteria about a month before their due date. The test involves taking swab samples from the lower vagina and rectum. Because it can take two or three days for test results to be returned, the general practice is to go ahead and begin treating a woman for GBS before confirmation of infection if a woman is in preterm labor. Most doctors think that this presumptive treatment is justified because as many as one in four women test positive for GBS. Ampicillin and penicillin are the antibiotics most commonly used for treatment.

A slightly increased number of basophilic hepatic foci were observed in chronic rat studies with budesonide and in carcinogenicity studies an increased incidence of primary hepatocellular neoplasms, astrocytomas (in male rats) and mammary tumours (female rats) were observed. These tumours are probably due to the specific steroid receptor action, increased metabolic burden on the liver and anabolic effects, effects which are also known from other glucocorticosteroids in rat studies and therefore represent a class effect. No similar effects have ever been observed in man for budesonide, neither in clinical trials nor from spontaneous reports.

    Glucocorticoids are potent anti-inflammatories, regardless of the inflammation's cause; their primary anti-inflammatory mechanism is lipocortin-1 (annexin-1) synthesis. Lipocortin-1 both suppresses phospholipase A2 , thereby blocking eicosanoid production, and inhibits various leukocyte inflammatory events ( epithelial adhesion , emigration , chemotaxis , phagocytosis , respiratory burst , etc.). In other words, glucocorticoids not only suppress immune response, but also inhibit the two main products of inflammation, prostaglandins and leukotrienes . They inhibit prostaglandin synthesis at the level of phospholipase A2 as well as at the level of cyclooxygenase /PGE isomerase (COX-1 and COX-2), [29] the latter effect being much like that of NSAIDs , potentiating the anti-inflammatory effect.

    Athletic drug testing is done to detect banned substances or performance enhancing agents in competitive-level athletes. In the , drug testing may occur in Olympic-level sports, National Collegiate Athletic Association sports (NCAA), and professional sports. The . Anti-Doping Agency (USADA) is the national anti-doping organization for the Olympic movement in the United States. With the USADA, as noted in the WADA code, testing may occur in competition or out of competition and can occur at any time and at any location. Testing can result in disqualifications, sanctions, and stripping of medals and world titles, as seen with professional cyclist Lance Armstrong.
