The following corticosteroids are used as immune system suppressants in treatment of ulcerative colitis: Cortisone; Prednisone; Hydrocortisone; Methylprednisolone; Budesonide, also known as Entocort, available for oral use or as an enema. Budesonide is metabolized faster than traditional steroids and appears to produce fewer systemic side effects.
Due to raised levels of inflammatory cytokines which lead to the increased expression of hepcidin, parenteral iron is the preferred treatment option as it bypasses the gastrointestinal system, has lower incidence of adverse events and enables quicker treatment. Hepcidin itself is also an anti-inflammatory agent.
Prednisone is absorbed in the gastrointestinal tract and has a half-life of 2–3 hours. [37] it has a volume of distribution of 0.4–1 L/kg. [39] The drug is cleared by hepatic metabolism using cytochrome P450 enzymes. Metabolites are excreted in the bile and urine. [39]
Synthetic pharmaceutical drugs with corticosteroid-like effects are used in a variety of conditions, ranging from hematological neoplasms [3] to brain tumors or skin diseases. Dexamethasone and its derivatives are almost pure glucocorticoids, while prednisone and its derivatives have some mineralocorticoid action in addition to the ...
Gastrointestinal system effects: swelling of the stomach lining, reversible increase in liver enzymes, and risk of stomach ulcers; Muscular and skeletal abnormalities, such as muscle weakness/muscle loss, osteoporosis (see steroid-induced osteoporosis), long bone fractures, tendon rupture, and back fractures
Glucocorticoids, however, not only reduce T cell proliferation, but also lead to another well known effect - glucocorticoid-induced apoptosis. The effect is more prominent in immature T cells still inside in the thymus, but peripheral T cells are also affected. The exact mechanism regulating this glucocorticoid sensitivity lies in the Bcl-2 ...
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus , stomach , and intestines .
Gastrointestinal physiology is the branch of human physiology that addresses the physical function of the gastrointestinal (GI) tract. The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products. The GI tract is composed of the alimentary canal, that runs from the mouth ...
