Pharmacology: Pharmacodynamics: Dexamethasone is a synthetic adrenocortical steroid and exerts anti-inflammatory effects by the same mechanism of action as naturally occurring glucocorticoids, but the mineralocorticoid action of dexamethasone is weaker than those of naturally occurring glucocorticoids.
Clinical Application: The results of clinical trials of Dexaltin Oral Paste including double-blind controlled trials on a total of 49 patients mostly with radiation stomatitis at 8 medical institutions in Japan are given in summary form as follows. (See Tables 1, 2 and 3.)

Pharmacokinetics: Dexamethasone is readily absorbed from the gastro-intestinal tract. Its biological half-life in plasma is about 190 minutes. Binding of dexamethasone to plasma proteins is about 77%, which is less than for most other corticosteroids. Up to 65% of a dose is excreted in urine within 24 hours. Clearance in premature neonates is reported to be proportional to gestational age, with a reduced elimination rate in the most premature. It readily crosses the placenta with minimal inactivation.

Intractable stomatitis or glossitis associated with erosion or ulceration.

Usually apply an adequate amount of Dexaltin Oral Paste to the affected area 1 to several times daily. The dose may be increased or decreased depending on the condition of the patient.

If a patient presents with symptoms such as blurred vision or other visual disturbances, the patient should be considered for referral to an ophthalmologist for evaluation of possible causes which may include cataract, glaucoma or rare diseases such as central serous chorioretinopathy (CSCR) which have been reported after use of systemic and topical corticosteroids.

Function of the pituitary-adrenocortical system: The prolonged use of Dexaltin Oral Paste may be associated with hypofunction of the pituitary-adrenocortical system.
