Low-dose and high-dose variations of the test exist. [4] The test is given at low (usually 1–2 mg) and high (8 mg) doses of dexamethasone, and the levels of cortisol are measured to obtain the results. [5] A low dose of dexamethasone suppresses cortisol in individuals with no pathology in endogenous cortisol production.
Dexamethasone is a fluorinated glucocorticoid medication [10] used to treat rheumatic problems, a number of skin diseases, severe allergies, asthma, chronic obstructive pulmonary disease (COPD), croup, brain swelling, eye pain following eye surgery, superior vena cava syndrome (a complication of some forms of cancer), [11] and along with antibiotics in tuberculosis.

Croup is usually treated with a single dose of steroids by mouth. [2] [7] In more severe cases inhaled epinephrine may also be used. [2] [8] Hospitalization is required in one to five percent of cases. [9] Croup is a relatively common condition that affects about 15% of children at some point. [4]
Dexamethasone – a synthetic glucocorticoid binds more powerfully to the glucocorticoid receptor than cortisol does. Dexamethasone is based on the cortisol structure but differs at three positions (extra double bond in the A-ring between carbons 1 and 2 and addition of a 9-α-fluoro group and a 16-α-methyl substituent).
A newer drug palonosetron is a pharmacologically distinct and highly selective, second generation 5-HT 3 receptor antagonist. [44] Palonosetron has two stereogenic centers and exists as four stereoisomers. [44] Palonosetron has longer half-life (40h) and greater receptor binding affinity (>30 fold; when compared to first generation antagonists ...

Infant respiratory distress syndrome (IRDS), also known as surfactant deficiency disorder (SDD), [2] and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs.
