Curcuma turmeric oil enhanced anti-dermatophytic drug activity against Candida albicans and Trichophyton mentagrophytes

Background: As per the World Health Organization survey, it has been found that dermatophyte infections are affecting around one-fourth of the world population. The dermatophytes are commonly keratinophilic in nature which can multiply and invade the keratinized tissues and affect various parts of the human body like nails, skin, and hair. The luliconazole is an antifungal drug utilized against dermatophytes which causes athlete's foot and ringworm etc. fungal infections of the skin or nails caused by Candida albicans (C.P. Robin) Berkhout and Trichophyton mentagrophytes (Robin) Blanchard. Objective: The study aimed to develop the luliconazole topical cream with turmeric oil and penetration enhancer to improve permeability and enhance antifungal activity. Methods: To prepare the luliconazole topical cream, various compositions of formulation were melted and mixed with varying concentrations of turmeric oil. The oil, drug, and aqueous phases were prepared separately and mixed stepwise in a vessel under continuous stirring at control conditions. Result: The optimized LC2 cream was showed pH 6.45±0.12, which is considered suitable to avoid irritation upon topical application. The LC2 cream formulation also showed significantly (p<0.05) more permeability with a permeation flux (0.347 mg/cm2/h) against an aqueous suspension of the drug (0.215 mg/cm2/h). The LC2 cream was followed the Higuchi model and showed the drug release from cream via a diffusion mechanism with super case II transport mechanism. Furthermore, the antifungal activity of optimized cream was found good than marketed cream. Conclusion: It is concluded that the prepared luliconazole cream can be an effective anti-fungal treatment with enhanced drug delivery into the skin to treat athlete's foot and ringworm etc. caused by dermatophytes namely C. albicans and Trichophyton spp.

Effect of Topical Products Extracted from Essential Oils of Capsicum, Apium graveolens and Mentha Plants on the Pain Intensity in Patients with Inflammatory Pain

Background: Inflammatory pain is the spontaneous hypersensitivity to pain that occurs in response to tissue damage and inflammation. Recently herbal remedies have been considered for less complications. The two topical products of Capsicum (Capex Topical cream) Apium graveolens and Mentha (CM lotion) can reduce the inflammatory. Since Capex Topical cream causes skin irritation, it seems that its composition with the other product could probably reduce this complication. Methods: This experimental study was performed on 60 patients referred to orthopedic clinic of Shahid Yahyanejad Hospital, Babol in 2018. Patients were randomly divided into three treatment groups. Data collection was done by a researcher-made questionnaire, which included two parts of individual characteristics and the severity of pain. The severity of pain was measured by visual analogue scale (VAS) before intervention and two and four weeks after the intervention. Data were analyzed using SPSS-16 software and P < 0.05 was considered as significant. Results: The results showed that the intensity of pain after use of each of the products decreased in all three groups. In addition, our results demonstrated that application of Capex Topical Cream was more effective that use of CM lotion in decreasing the pain intensity (P < 0.05). Moreover, the intensity of pain after topical application of the combined lotion of CM and Capex Topical cream significantly decreased (P < 0.05), however the decrease in pain intensity using combined solution was not significant compared to application of Capex Topical cream or CM lotion alone. Conclusions: The present study showed that the use of all topical products reduces the severity of pain and due to the less side effects and complications such as skin irritation in application of combined solution and better acceptance by patients, it could be suggested the use of combined solution as a better alternative to reduce inflammatory pains.

In vitro Evaluationof the Antimi- crobial Activity of a Topical Skin Preparation Containing 0.1% Polyhexanide vs a Topical Skin Prepa-ration Containing 1% Silver Sulfadiazine

Aim: The effective in vitro antibacterial activity on Staphylococcus aureus (S.aureus), Pseudomonas aeruginosa (P.aeruginosa), Klebsiella pneumoniae (K.pneumoniae),Escherichia coli (E.Coli) and the combination of S.aureus and K. pneumonia of a topical cream based on 0.1% polyhexanidewas compared to a topical cream based on 1% silver sulfadiazine.A topical cream containing 0,1% gentamicin was used as a positive control and a white blank topical cream was used as negative control. Materials and Methods: The in vitro antibacterial activities were determined by agar well-diffusion assay. Two-way Analysis of Variance (ANOVA) was used to test, by calculation of P-values, for significant antiseptic activity in bacteria treated with 0.1% polyhexanide topical cream compared to 1% silver sulfadiazine and to the negative and positive controls. Results: Among the derivatives tested, all the active topical creams analyzed were able to reduce microbial strains. The topical cream based on 0.1% polyhexanide showed a significantly higher antibacterial efficacy in comparison to the topical cream based on 1% silver sulfadiazine on S. aureus and K. pneumonia and on the combination of S. aureus and K. pneumoniae,while no significant difference was detected between the antibacterial activity of the two topical creams against P. aeruginosa and E. coli. Conclusion: These results provide a further insight into the antibacterial activity of polyhexanide and its non-inferiority compared to silver sulfadiazine towards certain bacterial strains (P. aeruginosa and E. coli) and superiority towards other (S. aureus and K. pneumoniae)and support the use of 0.1% Polyhexanide topical preparation for the treatment of wounds that are infected or at risk of infection.

Optimization And Evaluation Of Polyherbal Topical Cream

Herbal plants and their combination report therapeutic as a well synergistic effect that has been recognized in medicine. So, taking into account this factor, the polyherbal topical cream formulation was prepared by using plant extracts to improve patient compliance, enhance antimicrobial spectrum and enhance aesthetic properties. The study focused on the topical polyherbal cream formulation for delivery of the active constituents present in plants to improve skin diseases. The plant extracts of Ocimum sanctum (OS), Rubia cordifolia (RC), Glycyrrhiza glabra (GG) were utilized for the preparation of cream. The formulated cream was subjected to different evaluation parameters and the results depicted that the spreadability of the formulation was low (17.80 ± 1.10g. cm/sec) and that indicates trouble-free spreading, free from grittiness. In rheological properties all the cream formulations also exhibited the same non-Newtonian behaviour. Polyherbal topical cream showed potential antimicrobial activity against all selected microorganisms. Polyherbal topical cream (PHC-5) was ideal in terms of viscosity than other formulations and showed good drug release. Thus, the formulated polyherbal cream was found to be stable in terms of all physicochemical properties.
