Mometasone furoate (MF) is a glucocorticoid prodrug that faces the problem of poor aqueous solubility. Nanoemulsion-based topical gel of MF was formulated to enhance its solubility and potential of treating skin conditions. The selection of oil, surfactant and co-surfactant was done based on their solubility with the drug. The nanoemulsion was prepared using rose oil as the oil phase. Tween 80 and Transcutol P were used as surfactant and co-surfactant and they were blended in different ratios (1:0, 1:1, 2:1 and 3:1 w/w). The pseudo ternary diagrams were developed using these excipients and formulations exhibiting considerable nanoemulsion region were selected. The formulations were optimized by using Design Expert software for the globule size and cumulative percent release. The nanoemulsion formulations were characterized for in vitro release and stability study. The optimized nanoemulsions consisting of 2 % w/w oil, 30 % w/w Smix (Surfactant: Co-surfactant) and 67.9 % w/w water were consolidated into Carbopol 940 gelling agent to prepare three nanoemulsion-based gel formulations or nanoemulgels (NEG1-NEG3). Nanoemulgels were evaluated for their stability and ex vivo permeation of MF. The outcomes suggested that skin permeation of MF from all the nanoemulgel formulations was significantly enhanced as compared to the marketed mometasone furoate topical formulation.

Background: Oral inflammatory ulcers are one of the common complaints of patients attending out-patient clinics. Previous in vivo studies had shown that an Aqueous M. citrifolia Fruit Extract (AMFE) possessed anti-inflammatory and ulcer healing activities. Therefore, a standardized topical bioadhesive gel containing AMFE-phytosome was developed and determined for its oral ulcer healing efficacy in a rabbit model. Methods: The AMFE phytosome (AMFE-P) was prepared by a complexation method with the required amount of AMFE: Phosphatidylcholine: Tween 80 to weigh ratio of 2:1:0.2. Poloxamer 407 was used as a gelling agent. The oral ulcer was induced in male New Zealand white rabbits by topical application of acetic acid. Each test compound was applied to the ulcer for 10 days beginning on the second day after the ulcer induction. Complete ulcer healing on the specimen obtained on day 12 was observed histologically using the histological scoring protocol. Results: The optimized gel containing AMFE-P equivalent to AMFE 10%w/w (10%AMFE-P gel) showed the best bioadhesive gel quality, a smooth and homogeneous texture with an optimum viscosity and pH range used in human oral cavity, a good physical and chemical stability and the highest percentage cumulative release of total phenolic and scopoletin content. It was found that a daily application of 10% AMFE-P gel exerted a superior ulcer healing efficacy and a significantly rapid ulcer healing process than a twice daily application of topical gel containing AMFE 10%w/w or chlorhexidine 0.2%. Conclusion: These findings demonstrated that 10% AMFE-P gel has potential as a safe and effective alternative therapeutic agent for oral ulcers.

Abstract Background Pongamia pinnata (Fabaceae) is among those categories of plants mentioned in Ayurveda and traditionally known to use in several types of disease and disorders. The objective of the present work was to investigate the anti-psoriatic activity of Pongamia pinnata leaves extracts in Herbal gel formulation. Results Hydroalcoholic leaves extract of Pongamia pinnata was first subjected to phytochemical screening and quantification of phytoconstituents. Herbal gel was prepared containing Pongamia pinnata extracts using Carbopol 934 as gelling agent. The prepared gel formulations were studied for pH, viscosity, Spreadability and in vitro diffusion studies. The imiquimod-induced psoriatic mouse model, showed a prominent anti-psoriatic activity of the extract as evident through index grading. Treatment with extract confirmed a noteworthy reduction in psoriasis in the treated groups as there was a considerable diminution in the thickness and scaling of skin. Conclusions Lack of proper treatment and disadvantages associated with allopathic medicines pave the way to extensive research in natural products with anti-psoriatic activity. The present research scientifically justified the anti-psoriatic activity of the Hydroalcoholic extracts of Pongamia pinnata leaves.

The aim of the present study was to develop self-emulsifying drug delivery system (SEDDS) of aceclofenac for potential improvement in the in vitro dissolution. The Food and Drug Control Agency (FDCA) has put more stress on the quality, safety and efficacy of the dosage form. The use of design of experiments and quality by Design (QbD) in the development of self emulsifying drug delivery system (SEDDS) containing aceclofenac is demonstrated. The optimum formulation contained Labrafil M 1944 CS, Tween 80 and Transcutol P. The systematic approach enabled us in identifying the design space. The results revealed that while devising the control strategies during manufacturing, more attention should be focused on the ratios of oil to surfactant and surfactant to co-surfactant. The drug was released at a faster rate due to a large surface area. The current approach enabled us to develop a dosage form which is economic, patient-friendly and does not require assistance of a doctor or nurse, especially at remote places at odd hours.

Cocrystallization of drug with conformer is an immense approach used to explore the physicochemical properties of drug. The objective of the present work was to design formulate and evaluate the drug cocrystals of poorly soluble drug apremilast (APR) with saccharin. Methods: Cocrystals of APR were prepared using the solvent evaporation technique. The saturated solubility study and in vitro dissolution study of cocrystals were carried out. The prepared cocrystals were characterized by differential scanning calorimetry (DSC), X-ray diffraction (XRD), and Fourier-transform infrared (FTIR) spectroscopy. The topical gel of APR cocrystals was formulated optimized and evaluated using three-level factorial design. Results: The cocrystals of APR were prepared in 1:1 molar ratio with saccharin. APR cocrystals showed the improvement in solubility and dissolution as compared to pure APR. The formation of cocrystals was confirmed from change in endothermic peak of DSC and from shifting of FTIR spectra of cocrystals. Crystallinity of cocrystal was confirmed from XRD pattern and noteworthy change in 2θ values of the intense peak. The topical gel of APR cocrystals was formulated and optimized using three-level factorial design using Carbapol-940 and hydroxypropyl methylcellulose (HPMC) as a gelling agent. Conclusion: The cocrystals with altered physicochemical properties of APR were prepared with saccharin and formulated as a topical gel to overcome the problems related to oral administration.

Objective: Tween 80 has been used as a solvent for the extraction of phenolic compounds because this surfactant has both hydrophilic and hydrophobicproperties. Solid lipid nanoparticles (SLNs) have been developed to improve penetration through the skin layer. We investigated the efficacy of usingthe microwave-assisted micellar extraction (MAME) approach for extracting oxyresveratrol from Morus alba roots and also to develop an SLN lotion.Methods: The M. alba roots were extracted with Tween 80 in a microwave for 18 min, and the extract was used to develop SLN with differentconcentrations of glyceryl monostearate. The SLNs from M. alba root extracts were prepared by a high-speed homogenization technique (25,000 rpmfor 15 min). The SLNs produced were characterized as per particle size, polydispersity index (PDI), and zeta potential. The SLNs with the bestcharacteristics were used to formulate a lotion using a high-pressure homogenizer.Results: Extraction using MAME showed improved extraction efficiency. The oxyresveratrol concentration from the extract was 2.77%. The SLN with2.5% glyceryl monostearate showed the optimum result, with a particle size of 130.20 nm, a PDI of 0.278, and a zeta potential of −21.8 mV. The SLNlotion exhibited a particle size of 285.9 nm and a PDI of 0.360. The SLN lotion also had good penetration, with a flux of 4.70 μg cm−2/h.Conclusion: MAME is an efficient method for extracting oxyresveratrol from M. alba roots. The SLN with 2.5% glyceryl monostearate exhibited theoptimum characteristics, and the SLN lotion showed good characteristics, including skin penetration.
