A green, simple, and stability-indicating RP-HPLC method was developed for simultaneous determination of permethrin isomers in pharmaceutical preparations. The separation was based on a C18analytical column (150 × 4.6 mm, i.d., 5 μm). The mobile phase consisted of ethanol: phosphoric acid solution (pH = 3) (67 : 33, v/v). The elution was carried out at 30°C temperature with a flow rate of 1.0 mL/min. Quantitation was achieved with UV detection at 215 nm.
