curcumin and Acne-Vulgaris

The combination of herbal drugs with a topical antibacterial for managing a chronic disease like acne vulgaris has emerged lately to settle side effects and bacterial multidrug resistance. Mixed micelles (MMs) incorporated into nanogel were explored for hybrid delivery of curcumin (Cur) and fusidic acid (FA) combination presenting a multi-strategic treatment. Curcumin-fusidic acid-loaded mixed micelles (Cur-FA-MMs) were assessed for size, surface charge, compatibility, in vitro release, and encapsulation. The selected formula was further loaded into nanogel and investigated for viscosity, ex vivo permeation, and in vivo potential. Cur-FA-MMs exhibited uniform nanosized spherical morphology, and negative surface charge affording high encapsulation for both drugs with a biphasic in vitro release over a period of 48h and good colloidal stability. The attained Cur-FA-MM-loaded nanogel had optimum viscosity with remarkable permeation coefficient values nearly 2-fold that related to plain nanogel. The pharmacodynamic effect of Cur on FA was pronounced by the significant improvement of the skin's degree of inflammation, epidermal hypertrophy, and congestion in animals treated with Cur-FA-MM-loaded nanogel. In conclusion, micellar nanogel could enable the progressive effect of Cur (an antioxidant with reported antibiotic activity) on FA (antibiotic) and decrease the risk of emerging antibiotic resistance by enhancing the solubility and permeation of Cur.

Propionibacterium acnes acts a critical role in the development of inflammatory acne when it overgrows in pilosebaceous units. The spread of multiple drug resistance bacteria indicates a growing need for new antimicrobial agents. The objective of this study is to develop lipid vehicles to deliver curcumin and inhibit P. acnes in the skin. The inhibitory activities of the curcumin containing vehicles against P. acnes were studied by the bioluminescence assay. Curcumin accumulation patterns in neonate pig skin were studied using Franz diffusion cells and confocal laser scanning microscopy. The physicochemical properties of the curcumin containing vehicles including interfacial tension, size distribution and viscosity were analyzed. Significant curcumin accumulation (362±8 µg/g skin) was observed with the lipid vehicles developed herein. Curcumin (0.43 µg/mL) in the vehicles significantly inhibited the growth of P. acnes. Confocal laser scanning microscopy confirmed the formation of curcumin reservoir in the skin by the curcumin-loaded vehicles. Curcumin-loaded vehicles could efficiently accumulate in the skin and inhibit P. acnes in vitro. Our results highlight the potential of using vehicles containing lauric acid and curcumin as an alternative treatment for acne vulgaris.

Rauvolfia serpentina (L). Benth. ex Kurz. (Apocynaceae) possessing antibacterial properties are widely used in modern herbal medicines. Curcuma longa L. (Zingiberaceae), a readily available antiseptic, possess antioxidant, antibacterial, blood purifying and antiinflammatory properties and used in various skin creams. Azadirachta indica A. Juss. (Meliaceae) possess astringent, antiviral, discutient, stimulant and antibacterial properties and works excellently well against acne and keeps the skin healthy.. Acne is the common skin problem that 85% of the teenagers face today. In this study, poly herbal anti-acne face wash gels were prepared using two polymers Carbopol and hydroxy propyl methyl cellulose (HPMC) along with the extracts of plants Rawvolfia serpentina, Curcuma longa, and Azadiracta indica.. The gel formulations were prepared in four different concentrations of 50, 100, 200 mg/ml as Gel-CRB 100, Gel-HPMC 50, Gel-HPMC 100, Gel-HPMC 200, respectively. The formulations were tested for the anti-acne activity by turbidimetric method.. RESULTS showed that the gels were non-irritant, stable and posses anti-acne activity. The efficacy when tested with a standard was almost same to that of Clindamycin gel.. From this study, Gel-HPMC 100 was proved to be stable and considered as an effective herbal formulation for acne treatment.
