Abstract:
OBJECTIVETo provide content-measuring evidences for establishing the quality criteria of dexamethasone acetate ulcer pasta.
METHODSContent of dexamethasone acetate was assayed by the isonicotinyl hydrazine (INH) colorimetry.
RESULTSThe 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).
CONCLUSIONIt is easy, convenient, accurate and dependable for INH colorimetry to determine the content of dexamethasone acetate.
