Neuroactive steroids are also called as neurosteroids . They are endogenous steroids that rapidly alter neuronal excitability through interaction with ligand-gated ion channels and other cell surface receptors. Neuroactive steroid refers to steroids that are synthesized by an endocrine gland that reach the brain through the bloodstream and have effects on brain function. Neurosteroids have a wide range of potential clinical applications from sedation to treatment of epilepsy and traumatic brain injury. Ganaxolone is a synthetic analog of the endogenous neurosteroid. Allopregnanolone is under investigation for the treatment of epilepsy.
It is important to use the correct amount of topical steroid for your eczema, as instructed by your healthcare professional. Topical steroids should be applied with clean hands so that the skin just glistens.

These are based on the Finger Tip Unit (FTU), and explained in detail in our fact sheet which you can download as a pdf from the related documents to the right of this page.
Oral steroids enter the bloodstream to get to the lungs, so they can cause these and other systemic effects, particularly if used frequently or for long periods of time. Other effects include cataracts, increased blood sugar, lack of blood supply to some bones and suppression of the body's own production of steroids needed during stress. Since inhaled steroids reduce the amount of oral steroids that may be needed for asthma, they may be safer than just using as needed mediation in all but the mildest forms of asthma. If your child is given many courses of oral steroids, careful monitoring for some of these side effects may be necessary.
