A simple and rapid HPLC method for the determination of ciclopirox, oc
topirox, and pyrithiones in pharmaceutical or antidandruff formulation
s has been developed. HPLC was carried out on a Purospher(R) RP-18 end
capped column using acetonitrile-water containing 0.02 M ortophosphori
c acid and 0.5 mM EDTA. disodium salt, (68:32, v/v) as the mobile phas
e and UV detection at 305 or 340 Mn. The extraction procedure has been
validated analysing samples spiked with known amounts of the active p
rinciples. The recoveries were greater than 94% and the reproducibilit
y was within 3%.
