Abstract

The objective of this investigation was to develop an intra gastric floating drug delivery system of clarithromycin and also attempts were made to sustain the release of clarithromycin. Multiple-unit floating beads of clarithromycin were prepared from sodium alginate solution containing Hydroxypropylmethylcellulose (K100M) and sunflower oil by using emulsion-gelation method. These beads were evaluated for entrapment efficiency, drug loading, buoyancy and in vitro drug release. All formulations were the floating lag time below two minutes and shows total floating duration more than ten hours. It was observed that entrapment efficiency, drug loading and buoyancy was greater with formulation containing two percent sodium alginate solution and five percent calcium chloride solution along with 500mg HPMC and five ml sunflower oil (i.e.F14) and also the result of in-vitro dissolution studies reveals that the formulation F14 gave sustained release pattern of clarithromycin upto 12 hrs.

Abstract

This study compares the physicochemical properties of cefixime (CFX) solid dispersions prepared by freeze drying method. Solid dispersions of cefixime in poloxamer 188 were prepared and characterized by intrinsic dissolution, powder X-ray diffraction, Fourier transform infrared spectroscopy and Scanning electron microscopy. CFX:Poloxamer 188 solid dispersions showed increased dissolution rate than pure CFX. The Infrared spectroscopic studies showed interaction between CFX and Poloxamer 188 in solid dispersions. The scanning electron microscopy studies showed decrease in particle size of binary system as compared to particle of pure drug. The amorphous state of CFX coupled with presence of interaction between drug and Poloxamer 188. However, the antimicrobial activity of CFX was increased significantly by Poloxamer 188 against S. aureus and E. coli. The solid dispersion technique of CFX:Poloxamer 188 binary system provides a promising way to increase the solubility and dissolution rate of poorly soluble drugs.
