Non-halogenated topical corticosteroids

The low systemic exposure of des-ciclesonide following ciclesonide nasal aerosol administration was confirmed in a crossover trial in 29 healthy adults. The median C max of des-ciclesonide was 59 pg/mL following a single dose of ciclesonide nasal aerosol (296 mcg) compared to 602 pg/mL following a single dose of orally inhaled ciclesonide (320 mcg) and 12 pg/mL following a single dose of ciclesonide aqueous nasal spray (300 mcg). The pharmacokinetics of intranasally administered ciclesonide have been assessed in perennial allergic rhinitis patients resulting in similar exposure compared to healthy subjects.

The acute toxicity of budesonide is low and of the same order of magnitude and type as that of the reference glucocorticoids studied (beclomethasone dipropionate, flucinolone acetonide). Results from subacute and chronic toxicity studies show that the systemic effects of budesonide are less severe than or similar to those observed after administration of the other glucocorticosteroids . decreased body weight gain and atrophy of lymphoid tissues and adrenal cortex. An increased incidence of brain gliomas in male rats in a carcinogenicity study could not be verified in a repeat study, in which the incidence of gliomas did not differ between any of the groups on active treatment (budesonide, prednisolone, triamcinolone acetonide) and the control groups. Liver changes (primary hepatocellular neoplasms) found in male rats in the original carcinogenicity study were noted again in the repeat study with budesonide, as well as with the reference glucocorticosteroids. These effects are most probably related to a receptor effect and thus represent a class effect.

Weaker topical steroids are utilized for thin- skinned and sensitive areas, especially areas under occlusion, such as the armpit, groin, buttock crease, breast folds. Weaker steroids are used on the face, eyelids, diaper area, perianal skin, and intertrigo of the groin or body folds. Moderate steroids are used for atopic dermatitis , nummular eczema , xerotic eczema , lichen sclerosis et atrophicus of the vulva , scabies (after scabiecide) and severe dermatitis . Strong steroids are used for psoriasis , lichen planus , discoid lupus , chapped feet, lichen simplex chronicus , severe poison ivy exposure, alopecia areata , nummular eczema, and severe atopic dermatitis in adults.
