6 publicationsFormulation and Evaluation of Methimazole-Loaded Emulgel for the Treatment of Melasma
Melasma is a common acquired hyperpigmentation disorder characterized by the development of irregular, symmetrical, and brownish facial patches, which can significantly affect the appearance and quality of life of affected individuals. Methimazole, an antithyroid drug, has been investigated for its potential topical depigmenting activity due to its ability to interfere with melanogenesis. The present study was undertaken to develop and evaluate a methimazole-loaded emulgel intended for topical application in the management of melasma. Pre-formulation studies were carried out to determine the solubility, melting point, ultraviolet absorption maximum, and drug–excipient compatibility. The prepared formulations were evaluated for their physical appearance, homogeneity, pH, viscosity, spreadability, drug content, and in-vitro drug release characteristics. Drug–excipient compatibility was assessed using Fourier-transform infrared spectroscopy, while differential scanning calorimetry was employed to investigate the thermal characteristics of the formulation. The developed emulgels exhibited satisfactory physical characteristics with acceptable pH, viscosity, spreadability, and drug content, indicating their suitability for topical administration. In-vitro drug release studies demonstrated sustained release of methimazole from the emulgel formulations over the studied period. The release data were further analysed to understand the mechanism of drug release. Short-term stability studies were also performed to assess the physical and chemical stability of the prepared formulations. Overall, the study demonstrated the successful development of a methimazole-loaded emulgel with desirable physicochemical properties and controlled drug-release characteristics, suggesting its potential as a topical formulation for further investigation in the management of melasma. Emulgel have several merits like greaseless, easily spreadable, easily removable, emollient and transparency.
Development and Evaluation of Solid Lipid Nanoparticle-Loaded Polymeric Hydrogels Containing Dapsone.
Dapsone is a synthetic sulfone with antimicrobial and anti-inflammatory activity, but conventional topical formulations may provide limited skin penetration and short local retention. This study aimed to develop, optimize, and characterize a dapsone-loaded solid lipid nanoparticle (DDP-SLN) polymeric hydrogel for controlled dermal delivery. DDP-SLNs were prepared by hot homogenization followed by probe ultrasonication using glyceryl monostearate (GMS), soya lecithin, and Tween 80. A three-factor, three-level Box–Behnken design using Design-Expert® Version 13 was employed to optimize the formulation based on particle size, entrapment efficiency, and 12-h cumulative drug release. The optimized DDP-SLN dispersion was incorporated into Carbopol 934 hydrogel and evaluated for physicochemical, rheological, drug-release, and stability characteristics. The optimized DDP-SLN showed a particle size of 140.38 nm, PDI of 0.287, zeta potential of −35.0 mV, and entrapment efficiency of 87.93%. The hydrogel exhibited homogeneous texture, pH of 6.23 ± 0.08, viscosity of 8486.67 ± 70.95 cP, and spreadability of 18.42 g·cm/s. Cumulative drug release reached 87.90% over 12 h and followed the Higuchi model (R² = 0.9910), while the Korsmeyer–Peppas exponent (n = 0.612) indicated anomalous transport. The formulation remained stable under the evaluated storage conditions, demonstrating its potential as a topical delivery system for dapsone. The system was designed to enhance drug localization while providing sustained release and hydrogel performance. These findings demonstrate the suitability of combining SLN technology with a hydrogel to improve topical dapsone delivery and maintain formulation quality.

From Seeds to Sheild: Design and Evaluation of Herbal Nail Lacquer- A Natural Antifungal Approach Against Onychomycosis
Onychomycosis also referred to as dermatophytic onychomycosis or Tinea unguium, is a fungal nail infection primarily caused by dermatophytes (like Trichophyton rubrum), yeasts (like Candida albicans), and non-dermatophytic moulds. In this study, an effort was made to develop a herbal medicated antifungal nail lacquer using Caesalpinia bonducella seeds. The objective was to enhance clinical efficacy while improving patient compliance. Authenticated C. bonducella seeds were extracted and formulated into nail lacquers using suitable excipients, including film-forming agents, plasticizers, solvents, penetration enhancers, and resins. The prepared formulations were evaluated for various physicochemical and biological parameters such as smoothness, glossiness, non-volatile content, drug content, adhesion, diffusion, and antifungal activity (zone of inhibition). FTIR analysis confirmed drug–excipient compatibility by retaining characteristic peaks. Among the formulations, F5 was identified as the optimized batch and subjected to accelerated stability testing under ICH guidelines at 37 ± 2 °C for one month. The results showed no significant changes in its initial characteristics, while the formulation maintained excellent antifungal activity. Overall, the developed antifungal nail lacquer demonstrated safety, stability, and effectiveness, suggesting its potential as a novel dosage form for the treatment of dermatophytic nail infections such as onychomycosis. Its use may significantly improve therapeutic outcomes and patient adherence compared to conventional therapies.

1 publicationA Novel Approach To The Bilayer Floating Drug Delivery System: A Review
Gastro retentive drug delivery system (GRDDS), these dosage forms are designed to achieve prolonged gastric residence time in controlled release manner. The floating drug delivery system (FDDS) also comes under the gastro retentive drug delivery system. These type of formulations helps to improve the solubility of poorly soluble drugs and enhances the bioavailability of the drug. In gastrointestinal tract the absorption of dosage form or drug molecule is a highly variable process. To overcome all these physiological problems Novel Drug Delivery System (NDDS) plays an important role. FDDS works on the principle of buoyancy (the tendency of an object or a molecule float in a fluid or the upward force that a fluid exerts on an object) which allows the drug to remain in the gastric environment for a prolonged period of time without rapid passing into the intestine. Floatation of a drug is due to bulk density less than gastric fluids and so, remain buoyant in the stomach for a prolonged period of time. Releasing the drug slowly at the desired rate and increase the bioavailability of narrow absorption window drugs. This review helps to know the floating drug delivery system principle, advantages and disadvantages, need for floating bilayer tablets, challenges in bi-layer tablet manufacturing and characterization and evaluation methods for bilayer floating tablets.
