[Determination of the content of dexamethasone acetate in stomatology ulcer pasta].
OBJECTIVE
To provide content-measuring evidences for establishing the quality criteria of dexamethasone acetate ulcer pasta.


METHODS
Content of dexamethasone acetate was assayed by the isonicotinyl hydrazine (INH) colorimetry.


RESULTS
The good linear range was 6-16 microg/mL (r = 0.999 1). The average recovery of dexamethasone acetate was 98.9%, and relative standard deviation was low than 1% (n = 5).


CONCLUSIONS
It is easy, convenient, accurate and dependable for INH colorimetry to determine the content of dexamethasone acetate.
