Abstract

Aim: Using appropriate wound dressings is crucial when treating burn wounds to promote accelerated healing.Materials & methods: Sodium alginate (SA)-based gels containing Carboxymethyl cellulose (CMC) and Pluronic F127 were prepared. The formulations. SA/CMC/Carbopol and SA/CMC/PluronicF127 were loaded with aqueous root extract of Capparis sepiaria. The formulations were characterized using appropriate techniques.Results: The gels' viscosity was in the range of 676.33 ± 121.76 to 20.00 ± 9.78 cP and in vitro whole blood kinetics showed their capability to induce a faster clotting rate. They also supported high cell viability of 80% with cellular migration and proliferation. Their antibacterial activity was significant against most bacteria strains used in the study.Conclusion: The gels' distinct features reveal their potential application as wound dressings for burn wounds.

Keywords: Capparis Sepiaria; burn wounds; sodium alginate; topical gels; wound dressings; wound healing.

Plain language summary

Burn wounds are difficult to treat when invaded by microbes. Capparis sepiaria plant extract was loaded into gels. The gel formulations were non-toxic, with good antibacterial effects. These features are useful for the treatment of burn wounds.
