FORMULATION AND EVALUATION OF MOISTURIZING CREAM CONTAINING SUNFLOWER WAX

Objective: The main objective of the present investigation was to design, prepare and evaluate moisturizing cream using sunflower wax.Methods: In the present work 32 full factorial design was applied to study the effect of varying concentration of independent variables stearic acid (X1) and sunflower wax (X2) on dependent variables viscosity and spreadability. All of the prepared formulations of moisturizing cream were evaluated for its physicochemical parameters. Further, the optimized formulation and selected commercial moisturizer compared and evaluated for its physicochemical parameters like pH, particle size, spreadability, viscosity and in vitro occlusivity test.Results: Nine different formulations of the moisturizing cream were prepared and all the findings obtained were within the prescribed limit. When compared to the prototype formulation of cream, the formulation MF5 showed good viscosity, in vitro occlusivity and spreadability. From the nine different formulations, MF5 containing 2 % stearic acid and 2 % sunflower was chosen as the optimized formula. Optimization was done on the basis of in vitro occlusivity studies and physicochemical parameters.Conclusion: The results obtained in this research work clearly showed a promising potential of moisturizing cream containing a specific ratio of stearic acid and sunflower wax as emulsifiers. Thus it can be concluded that sunflower wax is incorporated in the moisturizing cream, to avail of its cosmetic benefits

FORMULATION AND EVALUATION OF OINTMENT CONTAINING SUNFLOWER WAX

Objective: The objective of the present work was to formulate and evaluate ointment using sunflower wax. Methods: In the present work, ointment formulations were prepared using sunflower wax by fusion technique. Sunflower wax base was compared with standard base for its pH, appearance, strength, spreadability, water number, and washability. Further, the optimized formulation was prepared with 2% salicylic acid and evaluated for its physicochemical parameters, compatibility study, drug content, in vitro drug diffusion, ex vivo permeability, and skin irritation test using rat skin. Results: All of the prepared formulations of ointments were evaluated for its physicochemical parameters and all the findings obtained were within the prescribed limit. As compared to the ointment prepared by prototype formulae as per USP and IP, the formulation F3 containing 97% white petrolatum and 3% of sunflower wax showed good viscosity, strength, and spreadability. Based on viscosity, strength, and spreadability, formulation F3 was chosen as an optimized formulation. Conclusion: The ointment consisting of white petroleum base 97% and 3% sunflower wax can be used for topical and systemic delivery of active ingredient salicylic acid. The results showed that sunflower wax can be used in ointment base as far as its pharmaceutical properties are concerned. It can effectively replace comparatively costlier available ointment bases

FORMULATION AND IN VITRO EVALUATION OF FAST DISSOLVING TABLET OF VERAPAMIL HYDROCHLORIDE

Objective: The main objective of this research work was to formulate and evaluate fast dissolving tablet of verapamil hydrochloride for the treatment of hypertension.Methods: In this study, fast dissolving tablet were prepared by wet granulation method by using croscarmellose sodium and sodium starch glycolate as superdisintegrants in the concentration of 2%, 4%, and 6%. Polyvinyl pyrollidone K30 is used as a binder. The designed tablets were subjected to various assessment parameters like friability test, hardness test, disintegration test, wetting time, in vitro drug release and drug content.Results: All the prepared formulations were subjected to various assessment parameters, and the findings obtain within the prescribed limit. The calibration curve of pure drug using various solvents like distilled water, phosphate buffer pH 6.8 was plotted. F1-F9 containing croscarmellose sodium and sodium starch glycolate in various concentration demonstrate the minimum disintegration time. Among all these formulations F8 shows disintegration time upto 19±0.06 seconds due to the high concentration of superdisintegrants. In vitro drug release was tested in phosphate buffer pH 6.8 at a time interval of 0, 1, 3,6,9,12,15 min. The F8 shows drug release 98.5±0.567%. Accelerated stability study of optimized formulation (F8) up to 2 mo showed there was no change in disintegration time and percentage drug release.Conclusion: The results obtained in the research work clearly showed a promising potential of fast dissolving tablets containing a specific ratio of crosscarmellose sodium and sodium starch glycolate as superdisintegrants for the effective treatment of hypertension.Â

Formulation and Evaluation of Mucoadhesive Buccal Tablet of Repaglinide

The aim of present investigation was formulation and evaluation of mucoadhesive buccal tablet of Repaglinide to study the effect of different polymers on release profile of drug for prolonged release. In this study mucoadhesive buccal tablet were prepared by direct compression method. Various rheological characteristics of the powder bed like bulk density, compressibility index, and angle of repose were evaluated and studied. Mucoadhesive buccal tablets were compressed on a 8 station mini press using 10 mm flat faced punches and were all assessed for weight variation, hardness, thickness, percent swelling index, mucoadhesive strength and in vitro release of the drug by using USP TDT 08L dissolution testing apparatus method II using a paddle at 50 rpm. Data was optimized by using 32 full factorial design by using software named as design expert and with the help of kinetic study. The stability studies showed that there is no decrease in the drug content of all formulations for the period of 2 months. Keywords: Buccal tablet, Repaglinide, HPMC K100M, Xanthan gum
