DiscussionObjective:Protoscolex plays an important role in the development and recurrence of
hydatid cyst. Albendazole is one of the
most effectual protoscolicidal agents for prophylaxis and relapse this disease,
nonetheless its low solubility and its
low intestinal absorption necessitates the presence of a drug carrier to
enhance its efficacy. In this study, the effect of
albendazole and its Nano form on
protoscolices In vitro and In vivo was evaluated.
Materials and Methods: Microemulsion method was used to prepare the Solid lipid
Nanoparticles (SLNs) containing albendazole. The protoscolices extracted from
hydatid cysts were maintained in RPMI 1640 for one week, and their survival
under the influence of albendazole and albendazole loaded SLNs on days 3 and 7
at concentrations of 250 and 500 µg/ml was examined. The live protoscolices
exposed on day 3 at a concentration of 250 ml were injected to mice for
evaluation of pathogenicity. Three months later, after the autopsy of the mice,
the pathogenicity was assessed.
Results: Protoscolicidal efficacy was highest in both
concentrations on day 7 for albendazole and on day 5 for nano-albendazole.
Following the autopsy of the mice for studying the growth of protoscolex
injected into these animals, cyst growth was reported in all mice, and only two
mice from the albandazole loaded SLNs group did not have any cyst.
Conclusion: Albandazole loaded SLNs showed a higher
protoscolicidal property than the free form of this drug; therefore, the use of
nano-formulation of this drug is recommended to prevent the onset of this
