Corticosteroids mechanism of action immunosuppression

Use of QVAR with a spacer device in children less than 5 years of age is not recommended. In vitro dose characterization studies were performed with QVAR 40 mcg/actuation with the OptiChamber and AeroChamber Plus ® spacer utilizing inspiratory flows representative of children under 5 years old. These studies indicated that the amount of medication delivered through the spacing device decreased rapidly with increasing wait times of 5 to 10 seconds as shown in Table 2. If QVAR is used with a spacer device, it is important to inhale immediately.

Desonate was approved by the FDA following two major clinical trials in 2006. Each randomized, double-blind, placebo-controlled study enrolled 582 pediatric patients (between the ages of 3 months and 18 years). [9] The patient was topically administered the drug or placebo two times a day for four weeks. Using the Investigator’s Global Severity Score (IGSS), the treatment was considered successful if at Week 4 there was at least a two (2) point decrease from the patient’s baseline IGSS. In clinical trial 1, 44% of patients succeeded successful treatment of Desonate versus 14% treated with the placebo. In clinical trial 2, 28% of patients succeeded successful treatment of Desonate versus 6% treated with the placebo.

Corticosteroids, including prednisone, are a class of powerful drugs that reduce inflammation and suppress the immune system. They are prescribed for a wide variety of conditions, including rheumatoid arthritis (RA) and lupus, as well as multiple sclerosis, some types of cancer, asthma and skin rashes – including those caused by poison ivy. They can be prescribed short-term – until a rash clears up or until another drug can take effect, for example – or they may be used long-term. Corticosteroids come in skin creams, injections and inhaled forms; however, this study examined only people who took them orally.

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.
