Corticosteroids mechanism of action psoriasis

Direct intravenous injection:
Use only methylprednisolone sodium succinate.
Reconstitute with provided diluent or add 2 ml of bacteriostatic water (with benzyl alcohol) for injection.
May be administered undiluted.
Administer directly into a vein over 3—15 minutes. Doses >= 2 mg/kg or 250 mg should be given by intermittent infusion (see below), unless the potential benefits of direct IV injection outweigh the potential risks (., life-threatening shock).
 
Intermittent intravenous infusion:
Use only methylprednisolone sodium succinate.
Dilute in D5W, % Sodium Chloride (NS), or D5NS injection. Haze may form upon dilution.
Infuse over 15—60 minutes. Large doses (., >= 500 mg) should be administered over at least 30—60 minutes.

Current use in High-Resource Settings
Corticosteroids are not currently labeled for use in preterm labor in the US; however, coricosteroids are commonly used for preterm delivery. Given the relatively low cost and ease of administration, increased penetration is limited by the ability to quickly diagnose an at-risk fetus. Cost savings associated with the avoidance of surfactant and respiratory support are substantial.

Application in Low-Resource Settings
Where surfactant and ventilation are less likely to be available, corticosteroid use has the potential to save lives. In facility settings and among skilled attendants, intramuscular injection is feasible. There are ongoing efforts to pre-load betamethasone into the Uniject device in order to further reduce the skill required for administration. This could expand the base of end users, but is not yet commercially available. Corticosteroid therapy is not advised for women who have systemic infections such as tuberculosis. Caregivers in regions with high prevalence of infectious disease must be more cautious before administration of this drug.

Lung disease: People with this condition often develop emphysema, with symptoms of a hacking cough, barrel-shaped chest, and difficulty breathing. If you have this condition and smoke or are exposed to tobacco smoke, it accelerates the appearance of emphysema symptoms and lung damage.

Liver disease: Alpha-1 antitrypsin deficiency also cause liver disease in some people with the condition, that include liver cancer, cirrhosis of the liver, an abnormally large liver (hepatomegaly), liver failure, and hepatitis. Liver damage from alpha-1 antitrypsin deficiency causes symptom of a swollen abdomen, swollen legs or feet, and jaundice.

Treatment of AATD depends upon the severity of symptoms. FDA approved drug for AATD is an orphan product called alpha-1-proteinase inhibitor (human), sold under the brand name "Prolastin."

Because of these side effects, doctors frequently choose safer medications, such as the 5-ASA drugs and antibiotics, as initial therapy. But there are a number of ways to reduce the risk of developing side effects. These include rapid but careful tapering off of steroids; alternate-day dosing; rectally applied corticosteroids; and rapidly metabolized corticosteroids such as budesonide (described above). To help prevent osteoporosis, many doctors routinely prescribe calcium supplements as well as multivitamins that contain vitamin D. Another option is the use of bisphosphonates, such as risedronate (Actonel®) and alendronate (Fosamax®). These compounds, which have been shown to help avert bone loss, are effective in treating and preventing steroid-induced osteoporosis.
