OBJECTIVES: The aim of this study was to determine the influence of vehicles and penetration enhancers on the penetration and permeation of cinnarizine (CNZ) through the skin.
MATERIALS AND METHODS: Topical formulations based on hydrogel, o/w emulsion and oleaginous cream were prepared. After determination of physical properties of formulations, the penetration and permeation of CNZ through the stratum corneum and full-thickness skin was investigated by an ex vivo study.
RESULTS: The cumulative amount of CNZ permeated from the base hydrogel formulation was about 5 times higher than the base o/w emulsion and base oleaginous cream formulations. The incorporation of penetration enhancers to the base hydrogel and o/w emulsion formulations generally increased CNZ penetration through the skin. Transcutol® was confirmed to provide the highest penetration in the hydrogel formulation. Propylene glycol was found to be the most suitable penetration enhancer for CNZ in the oleaginous cream. Glycerol and oleic acid displayed the highest effect in the o/w emulsion.
CONCLUSION: It was concluded that the hydrogel containing Transcutol® provided the highest penetration through the skin among all formulations and this formulation could be an alternative to the oral route in the treatment of Ménière's disease and motion sickness. Thus, the risk of systemic side effects caused by oral medication can be reduced or eliminated.
