Background/Objective:
The primary treatment for cysts is surgery, including removing the cyst and administering the appropriate chemical drugs. Herbal remedies have gained popularity as a viable and secure alternative to conventional pharmaceuticals. It may be advantageous to use nanocapsules to overcome the bioavailability challenges associated with herbal remedies like curcumin. The present study aims to provide insights into the effectiveness of curcumin nanocapsules in treating hydatid infections.
Methods:
Curcumin-loaded oil-in-water surfactant-based biocompatible nanomicelles were developed from dissolving Curcumin in 1% (w/w) solutions of ethyl butyrate oil by dissolving an amount of fatty acid sodium caprylate (SC, 0.09 g) and F127 (0.009 g), phosphate-buffered saline (PBS at pH 7.4) under vigorous stirring at a fixed ethyl butyrate-to-surfactant molar ratio of 10 and final total volume of 50 mL. The excess of free PHT was eliminated by dialysis for 24 h. Following five months after infection, 45 mice were divided into six groups. Groups 1, 2, and 3 were treated daily with curcumin nanocapsules (0.5, 0.25, 0.125 mg/ml) for one month. Group 4 was treated with curcumin (0.5 mg/ml), group 5 was treated with albendazole (150 mg/kg), and group 6 was the negative control group without treatments (only received saline). A detailed analysis of the cysts' physical characteristics, including their size and weight, has been conducted.
Results:
The mean zeta potential spectrum of the nanocapsules was -33.96 mV. Regarding the total cyst numbers, all three nanocapsule groups had significantly lower total cyst numbers than the curcumin, albendazole, and negative control groups. Regarding the total cyst weight, all three nanocapsule groups had a significantly lower total cyst weight than the curcumin and negative control groups. Regarding the cyst with the maximum size, nanocapsules groups 1 and 2 had a significantly smaller size than the curcumin, albendazole, and negative control groups.
Conclusion:
The current study found that encapsulation positively affects curcumin efficacy as a superior alternative to chemical drugs, offering both biological advantages and environmental benefits.
