Phytochemical screening and anti-inflammatory actions of Alangium salviifolium root extract.

Alangium salviifolium root was screened for phytochemical and anti-inflammatory properties. The percentage inhibition of carrageenan induced paw oedema was studied in rats. Alangium salvifolium gave maximum extractive values with Ethanol and the Loss on Drying value, total ash value and acid-insoluble ash and water soluble ash values were within limits. The extract gave positive tests for phytosterols, triterpenes, flavonoids, carbohydrates and alkaloids. The extract was free from glycosides, saponins, tannins, proteins and amino acids. In acute toxicity studies, Alangium salviifolium root extract was found to be safe up to 3000 mg kg⁻¹, p.o. in the albino rats. The Alangium salviifolium root gave significant per cent inhibition of the maximal paw oedema and very highly significant per cent inhibition of total paw oedema during 6 h. This study revealed that Alangium salviifolium root has good anti-inflammatory actions when compared with Diclofenac sodium.

Preparation of Fluconazole ß-Cyclodextrin Complex Ocuserts: In Vitro and In Vivo Evaluation.

The main purpose of the present study was to develop ocuserts of Fluconazole ß-CD (beta-cyclodextrin) complex and to evaluate both in vitro and in vivo. Fluconazole was made complex with ß-CD, and the release rate was controlled by HPMC K(4)M and ethyl cellulose polymers using dibutyl Phthalate as permeability enhancer. Drug-polymer interactions were studied by Fourier transform infrared spectroscopic studies. The formulated ocuserts were tested for physicochemical parameters of in vitro release and in vivo permeation in rabbits. The optimized formulations (F-5 and F-8) were subjected to stability studies. The formulated ocuserts were found to have good physical characters, thickness, diameter, uniformity in weight, folding endurance, less moisture absorption, and controlled release of drug both in vitro and in vivo. The optimized formulations retained their characteristics even after stability studies. The study clearly showed that this technique was an effective way of formulating ocuserts for retaining the drug concentration at the intended site of action for a sufficient period of time and to elicit the desired pharmacological response.
