Background. The combined ointment with isohydrafural and fluocinolone acetonide contributes to the diversification of the treatment of dermatitis and psoriasis associated with infections. Complex stability studies were performed to ensure the quality of it during the shelf life. Objective of the study. Stability study and determination of shelf life of the combined ointment containing isohydrafural and fluocinolone acetonide. Material and Methods. Three series of ointment were tested by the real-time method (temperature 25± 2°C; relative humidity 60 ± 5%) over a period of 30 months, periodically determining the appearance, homogeneity, pH, viscosity, identity, purity and assay. It was used: OHAUS DV215 CD electronic balance, Shimadzu LC-20 A HPLC, Consort C861 pH meter and Fungilab rheometer. Results. At 24 months after storage, the three series of the ointment proved to be homogeneous, with a pH between 5.76 and 5.53. The rheograms showed a pseudoplastic behavior, with a slight thixotropy, with a viscosity between 73.1 and 71.1 cP. The active substances were detected at the characteristic retention times: isohydrafural-3 minutes, fluocinolone acetonide-5.9 minutes and no additional peaks occurred. The content of active substances was within the permitted limits: 0.0980.11% (m/m) for isohydrafural and 0.0248-0.025% (m/m) for fluocinolone acetonide. Conclusion. The combined ointment containing isohydrafural and fluocinolone acetonide was found to be stable under the storage conditions stipulated in the quality specification. The established shelf life is 24 months. |
