Clotrimazole

To develop a simple, precise, accurate, and stability indicating a UV-method for estimation of Clotrimazole. In bulk and formulated dosage form. The method was under subjected to stress degradation at different conditions recommended by the International Conference on Harmonization (ICH). The drug samples are generated and used for the degradation studies. The λmax of the Clotrimazole was found to be 220 nm. The linearity of calibration curve (Absorbance Vs Concentration) in pure solution was checked over the concentration ranges of about 5-30μg/ml for Clotrimazole respectively, with the correlation coefficient higher than 0.999. The regression equation of the curve was Y = 0.0168x + 0.0041. The % RSD was found to be within the limit as per ICH guidelines. The obtained percentage recovery of Clotrimazole was found to be within the limit 100% ± SD. The proposed method can be successfully applied for the method development, validation and stress degradation studies of Clotrimazole. The percentage degradation limit should be 5-20%. The drug Clotrimazole was found to be within the limit.

Ferulic acid (4-hydroxy-3-methoxy cinnamic acid) isolated from the aerial parts of Cansjera rheedii J.Gmelin (Opiliaceae) has been tested for its antimicrobial activity The antimicrobial activity have been studied with ferulic acid  against Stapylococcus aureus, Bacillus substilis, Escherichia coli, Salmonilla paratyphi, Candida albicans, Aspergillus fumigates which gave significant results of activity against Ciprofloxacin & Clotrimazole as standards. 

The purpose of this research was to develop a desired topical formulation containing clotrimazole for treatment of fungal infections like eczema, itching, pruritis etc. Topical formulation enriched with SLN of clotrimazole were prepared. The solid lipid nanoparticulate dispersion of clotrimazole was prepared by hot homogenization technique using polymers like Carbopol 934, mannitol and PEG 6000. The nanoparticulate dispersion was evaluated for various parameters such as physical evaluations, particle size, diffusion studies, DSC, SEM, stability studies. The solid lipid nanoparticulate dispersion showed mean particle size less than 1000 nm. Differential scanning Calorimetry studies revealed no drug excipient incompatibility. Diffusion studies release profile of clotrimazole from nanoparticulate dispersion showed prolonged drug release. And all other evaluations were found to be complied the limits. Thus it can be concluded that formulation of SLN containing clotrimazole can be successfully formulated to localize the drug in the skin for to treat topical fungal infections.
