Abstract

In current senario, various plant have been studied for their diverse applications as excipients like binders, granulating agents, disintegrants, emulsifiers, suspending agents, gelling agents, mucoadhesive agents, matrix-formers, release retardants, enteric resistants, etc., in various pharmaceutical dosage forms. Among these polysaccharide okra mucilage is an emerging excipient, which is being used and investigated for the preparation of various dosage forms like suspensions, emulsions, tablets, gels, creams, beads, spheroids, microparticles, nanoparticles, ophthalmic preparations, and buccal patches, etc. The major objective of the present investigation was to extract a natural polymer (okra gum) with its characterization as pharmaceutical binder and to formulate, develop, and evaluate the compression-coated tablet using okra as binder along with synthetic hydrophilic polymer. A novel extraction method was carried out using fresh unripe pods of okra (ladies finger) with the aid of organic solvents and its characterization was done. The core tablets were prepared by direct compression method which was compression coated with okra gum after the extraction of the okra gum was carried out, the yield of mucilage obtained was 10%. It is considered as a proof for the purity of the mucilage extract. The above study reveals that the polymers were subjected to the Fourier transform infrared and differential scanning calorimetry thermogram had no significant interactions between the drug and the polymers. In the present aspect of the study was to evaluate the efficacy of okra gum that has been used as a tablet binder. It is easily available and inexpensive. Okra gum as a binder produces tablet formulations with sustained release formulations. The current chapter deals with a comprehensive and useful discussion on extraction & isolation, chemical composition and properties of polysaccharide okra mucilage.
