The aim of this work was to develop and evaluate a minoxidil foamable emu oil emulsion with the purpose of improving minoxidil permeation into the skin, increasing hair growth, reducing skin irritation, and increasing consumer compliance. Minoxidil was dissolved in a solvent system comprising ethanol: glycerin: lactic acid: water (10:20:5:65). The foamable emulsion was prepared by mixing the oil phase with minoxidil solution using different amount of various emulsifiers. Seventeen formulations were prepared and the most stable foamable emulsion was selected and evaluated for various pharmaceutical parameters such as homogeneity, pH, stability to centrifugal stress, freeze-thaw and foamability. The adopted formulation showed good pharmaceutical characteristics. In vitro release rate of the formulations were evaluated using Franz diffusion cell using phosphate buffer pH 7.4 and ethanol as the receiver medium at sink condition. The release rate of formulations was found to obey Higuchi kinetic model. Experimental animal study was performed to evaluate hair growth potential of the formulation. Different cyclic phases of hair follicles, like anagen, and telogen phases, were determined at one month period. Histological study after treatment with adopted formulation exhibited greater number of hair follicles in anagenic phase (96%) which were higher as compared to marketed 5% minoxidil solution (Pakdaru® 70%) and the control group (42%). From animal study it was concluded that the selected formulation exhibited a significant potency in promoting hair growth in comparison with marketed 5% minoxidil solution Pakdaru®.
Background:People strive to maintain the best look and have a youthful appearance. The skin around the eye is an area without many oil glands and collagen in comparison to the body rest, so it is more prone to fine lines and dehydration, which makes it look dull. The aim of this research is to develop and evaluate in vivo efficacy of an anti-wrinkle and dark circle eye pad consisting of 3% w/w caffeine and 1% vitamin K in a convenient, healthy, and cosmeceutical base.Materials and Methods:Pre-emulsions containing selected ingredients in a specified effective concentration were prepared. The selected formulation, based upon pharmaceutical parameters, was coated on a nonwoven fabric in an eye counter shape, and stored in a jar. Then in vivo trial was carried out for investigation of its anti-wrinkling efficacy on 11 healthy women. In a single blind trial, the sample pad was applied under the right eye and the placebo pad, consisting of water, was placed under the left eye simultaneously. The efficacy and safety of the formulation was evaluated visually and with a multi skin test MC 900 instrument.Result:After four weeks, the skin around the right eye of all the subjects experienced a reduction in the depth of wrinkles and dark circles, and from a subjective point of view, the appearance and elasticity of the skin were improved.Conclusions:The caffeine pad containing vitamin K in an Emu oil base shows an improvement in eye counter appearance with anti-dark circle capacity and as an emollient.
Gracilaria algae is red macro algae which has demonstrated considerable antiinflammatory effects. Our objective was to compare the efficacy of Gracilaria algae topical cream 3% vs Clobetasol cream 0.05% in treatment of plaque-type psoriasis. Thirty adult patients with baseline modified Psoriasis Area and Severity Index (PASI) score ≤12 were randomized to receive either Clobetasol or Gracilaria algae cream on right or left-sided symmetric plaques once daily for 8 weeks and follow-up of 4 weeks. Modified PASI score, patient's satisfaction using VAS and global physician assessment score were assessed to evaluate clinical response. Thirty patients with 94 symmetrical psoriasis plaques were enrolled in this trial. The mean baseline modified PASI score of both sides was similar; however, at the end of trial, modified PASI score was reduced more on the sides treated with Gracilaria algae cream (0.80 ± 0.19% vs 0.63 ± 0.25%, P < .05). No significant difference was found regarding mean physician global assessment score between the two groups (P > .05). Patients' satisfaction was significantly higher in favor of algae cream only at week 8 of the intervention (P < .05). Gracilaria algae cream can be an effective and safe alternative of Clobetasol in the treatment of plaque type psoriasis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
