Physicochemical investigation and in vivo activity of anti-malarial drugs co-loaded in Tween 80 niosomes.

Drugs used for the treatment and prevention of malaria are often plagued by the problem of development of resistance. This has hampered their therapeutic efficiency and rendered them ineffective for monotherapy. However, if re-packaged and combined properly, many of these neglected anti-malarial drugs can possibly find their way back into the treatment regime. The present study evaluates the use of curcumin (CC) and primaquine (PRI) as an anti-malarial combination, packaged within niosomes, in comparison to their respective monotherapy options. It was observed that in Plasmodium berghei-infected mice, mice treated with a combination of 35 mg/kg of CC along with either 5 mg/kg or 1 mg/kg body weight of PRI demonstrated 100% anti-malarial activity and survivability beyond 20 days. The niosome-based PRI-CC combination therapy provided increased protection and survival rate that was associated with prevention in recrudescence. The findings of the study suggest that niosome-based PRI-CC combination therapy may be a promising approach in the treatment of malaria.
